I'm attempting to setup a remote session in PowerShell to a server but failing to do so and hit a wall in my troubleshooting.
On the server I want to remote to I have done:
* Enable-PSRemoting
* Restarted and winrm quickconfig to confirm
On my client from where I want to connect to servers I'm attempting to add trusted hosts via:
winrm s winrm/config/client '#{TrustedHosts="servername"}'
This fails with: "WSManFault
Message = The client cannot connect to the destination specified in the request."
Server is standalone and not in a domain, does not have firewall enabled (I can RDP to it just fine.)
Right now I'm simply trying to establish a 1to1 connection to perform some tests so there are no certificates included either so I was under the impression that the HTTPS listener would not be needed if I use trusted hosts?
"Did you enable WinRM on client as well? – PetSerAl "
This was the issue, the client trying to manage the server was not configured with WinRM.
Works well with winrm quickconfig and then say no to setting up a listener!

I am trying to remotely manage a windows server which is Azure AD Domain joined. I have activated winrm on both machines. My user has administrator rights and I am working from an elevated prompt. I have even set the Server as trusted host just in case. No matter what I try I keep getting this error message.
Connecting to remote server xxx failed with the following error message: The WinRM client cannot process the request. If the authentication schme is different from Kerberos, or if the client computer is not joined to a domain, then HTTPS transport must be used or the destination machine must be added to the TrustedHosts configuration setting. Use winrm.cmd to configure TrustedHosts. Note that computers in the TrustedHosts list might not be authenticated. You can get more information about that by running the following command: winrm help config. For more information, see the about_remote_Troubleshooting Help topic.

I am connected via VPN to the company network, I can also ping the server. I also successfully opened a telnet to the server on the port winrm uses normally.
What am I missing?
I successfully enabled PSRemoting on my Server 2008 R2.
I'm able to do a remote-pssession from within the same network using the hostname as target.
I'm failing when I try to use the IP-Address as target from any computer (within the network or from another network (for example via VPN)).
I want to be able to use remoting through my VPN connection where I have to use the IP-Address since the hostname can't be resolved.
I don't want to add names into my hosts-file because there are a few other servers at our clients' that have the same dns-name and I don't want to remove and insert the name-ip-address-association again and again.
I hope someone can tell me how to allow the psremoting-target to be called via IP.
Edit: To be more specific, I want to be able to run this:
Enter-PSSession -Computername 192.168.123.123 -credentials $cred
But I'm only able to run that command if I pass a hostname to "-Computername"
Edit2:
I'm getting following errormessage when I try to login using the ip instead of the hostname (from the internal network):
Enter-PSSession : Connecting to remote server failed with the following error message : The WinRM client cannot process
the request. Default authentication may be used with an IP address under the following conditions: the transport is HT
TPS or the destination is in the TrustedHosts list, and explicit credentials are provided. Use winrm.cmd to configure T
rustedHosts. Note that computers in the TrustedHosts list might not be authenticated. For more information on how to se
t TrustedHosts run the following command: winrm help config. For more information, see the about_Remote_Troubleshooting
Help topic.
Edit3:
I know about the trusted-hosts setting of WSMan, but that doesn't seem to be the problem. It is already set to "*" (I did that right after enabling remoting), but I still can't connect to that server using the ip as target-computername, but I'm able to connect using the hostname as target-computername. Seems like there's something like the binding in IIS that prevents the listener to listen on requests that target the ip-number instead of the hostname. But IIS isn't installed. I don't know where to look for such a setting.
Update 2011-07-12:
Okay, I think that trustedhosts-setting is not the problem because I CAN connect from our DC via hostname but not if I use the ip-address of the destination for the computer-param.
I think, the problem must be the listener. Maybe the listener takes no requests that were targeted to the destination-ip instead of the destination-hostname. But I don't know how to change that.
The error message is giving you most of what you need. This isn't just about the TrustedHosts list; it's saying that in order to use an IP address with the default authentication scheme, you have to ALSO be using HTTPS (which isn't configured by default) and provide explicit credentials. I can tell you're at least not using SSL, because you didn't use the -UseSSL switch.
Note that SSL/HTTPS is not configured by default - that's an extra step you'll have to take. You can't just add -UseSSL.
The default authentication mechanism is Kerberos, and it wants to see real host names as they appear in AD. Not IP addresses, not DNS CNAME nicknames. Some folks will enable Basic authentication, which is less picky - but you should also set up HTTPS since you'd otherwise pass credentials in cleartext. Enable-PSRemoting only sets up HTTP.
Adding names to your hosts file won't work. This isn't an issue of name resolution; it's about how the mutual authentication between computers is carried out.
Additionally, if the two computers involved in this connection aren't in the same AD domain, the default authentication mechanism won't work. Read "help about_remote_troubleshooting" for information on configuring non-domain and cross-domain authentication.

HOW TO USE AN IP ADDRESS IN A REMOTE COMMAND
-----------------------------------------------------
ERROR: The WinRM client cannot process the request. If the
authentication scheme is different from Kerberos, or if the client
computer is not joined to a domain, then HTTPS transport must be used
or the destination machine must be added to the TrustedHosts
configuration setting.
The ComputerName parameters of the New-PSSession, Enter-PSSession and
Invoke-Command cmdlets accept an IP address as a valid value. However,
because Kerberos authentication does not support IP addresses, NTLM
authentication is used by default whenever you specify an IP address.
When using NTLM authentication, the following procedure is required
for remoting.
1. Configure the computer for HTTPS transport or add the IP addresses
of the remote computers to the TrustedHosts list on the local
computer.
For instructions, see "How to Add a Computer to the TrustedHosts
List" below.
2. Use the Credential parameter in all remote commands.
This is required even when you are submitting the credentials
of the current user.
Try doing this:
Set-Item WSMan:\localhost\Client\TrustedHosts -Value "*" -Force
I test your assertion in my infrastructure the IP address is not the problem the following works for me :
PS C:\Users\JPB> hostname
JPBCOMPUTER
PS C:\Users\JPB> Enter-PSSession -ComputerName 192.168.183.100 -Credential $cred
[192.168.183.100]: PS C:\Users\jpb\Documents>
[192.168.183.100]: PS C:\Users\jpb\Documents> hostname

If you try to work accross a VPN you'd better have to have a look to the firewall settings on the way to your server. Installation and Configuration for Windows Remote Management can help you. The TCP port WinRM is waiting on are :
WinRM 1.1 and earlier: The default HTTP port is 80.
WinRM 2.0: The default HTTP port is 5985.
Edited : According to your error can you test this on youclient computer :
Set-Item WSMan:\localhost\Client\TrustedHosts *
The guys have given the simple solution, which will do be you should have a look at the help - it's good, looks like a lot in one go but it's actually quick to read:
get-help about_Remote_Troubleshooting | more
On your machine* run 'Set-Item WSMan:\localhost\Client\TrustedHosts -Value "$ipaddress"
*Machine from where you are running PSSession
On Windows 10 it is important to make sure the WinRM Service is running to invoke the
command
* Set-Item wsman:\localhost\Client\TrustedHosts -value '*' -Force *
For those of you who don't care about following arbitrary restriction imposed by Microsoft you can simply add a host file entry to the IP of the server your attempting to connect to rather then use that instead of the IP to bypass this restriction:
Enter-PSSession -Computername NameOfComputerIveAddedToMyHostFile -credentials $cred
Please try the following on the client:
Run the following command to restore the listener configuration:
winrm invoke Restore winrm/Config
Run the following command to perform a default configuration of the Windows Remote Management service and its listener:
winrm quickconfig
After you configured winrm again, make sure host is trusted:
Set-Item wsman:\localhost\Client\TrustedHosts -value "$ipaddress" -Force
Try remote connect again
Reference
Configure winrm for HTTPS
I spend a great amount of time and finally got the solution. Following are the steps to do fix this -
Go to Control Panel\All Control Panel Items\Network and Sharing Center\Advanced sharing settings in control panel
Make sure machine discovery in domain and guest is ON.
Open powershell in administrator mode on client machine and run winrm quickconfig and winrm set winrm/config/client '#{TrustedHosts="*"}'
As Don touched on this, here is more info
Using the IP is Kerberos authentication problem
If you are on a AD Domain and need a more elegant solution than allowing NTLM and trusted hosts: https://learn.microsoft.com/en-us/windows-server/security/kerberos/configuring-kerberos-over-ip
" Beginning with Windows 10 version 1507 and Windows Server 2016, Kerberos clients can be configured to support IPv4 and IPv6 hostnames in SPNs.
By default Windows will not attempt Kerberos authentication for a host if the hostname is an IP address. It will fall back to other enabled authentication protocols like NTLM. "
Note that there might be GPOs limiting / disabling NTLM in the domain - since this can be a security risk
To check run "RSOP".
GPOs are under: Computer Configuration > Policies > Windows Settings > Security Settings > Local Policies/Security Options > Network Security
Allowing basic auth and allowing "*" in Trusted hosts makes me cringe a bit :)

I'm currently trying to connect to my Virtual Machine with Windows Server 2012 Datacenter and connect to it via Certification Test Tool 1.2 for Azure. And always getting this error:
Connecting to remote server xyz-vm.westeurope.cloudapp.azure.com
failed with the following error message: WinRM cannot complete the
operation. Verify that the specified computer name is valid, that the
computer is accessible over the network, and that a firewall exception
for the WinRM service is enabled and allows access from this computer.
By default, the WinRM firewall exception for public profiles limits
access to remote computers within the same local subnet. For more
information, see the about_Remote_Troubleshooting Help topic.
I guess the tool is using PSRemot so I checked that:
"winrm" is running.
"PS Remoting" is enabled in the firewall.
Port 5985 and 5986 are in the network security group in Azure and at the local VM Firewall allowed.
I tested the connection via Test-WSMan and I got a connection:
screenshot. But the connection with the Certification Test Tool still failed.
Even after turning the Firewall of the VM completely of, it didn't work
Thank you for your Help
Can you please run in cmd on the Virtual Machine netsh winhttp show proxy
If this shows port 8080 could you then run netsh winhttp reset proxy
According to #Shengbao Shui - MSFT
For a existing VM, you also check this blog. You need create a self-certificate and enable https.
I am getting below error message when I try to access one of the AWS Cloud Servers through"Enter-PSSession" cmdlet. I have Admin rights on the server and provide the necessary credential as well but still no gain. Please help to resolve or suggest alternate way to remotely access the Server.

Make sure that the server behind that name has the proper IP address.
You can do that if you ping the host name, and then ping the turned IP with attribute -a
Ping server.com
Ping -a <IP returned by that hostname>
If the second ping return different hostname, thats were you have problem.
If it does not return any hostname, then it might be behind switch or firewall rule that does not allow reverse lookup.
If everything is good, try to see if the WinRM is working with the following command
Test-WSMan <hostname or an IP>
If that is return the ProductVersion then that machine has WindowsRemote Manager enabled.
If that is not working then you dont have windows remote management enabled on that machine, and of course check the firewall.
But if you dont have an issue here then you better check if you have CredSSP enabled/disabled, but for that you would need to read a bit more, here is a nice article about it :
https://4sysops.com/archives/using-credssp-for-second-hop-powershell-remoting/
And if after all that you still have the issue, make sure you know if you are using Certificates to authenticate, if thats the case it really depend on how your PKI is all set.
Make sure the remote host is reachable over you network .
if reachable over network, make make sure remoting is enabled on the derstination server.
if windows firewall service is not running, start it on the destination server .
I'm testing WinRM connection using Command Prompt on my local and remote machine and my question is devided into two parts.
PART I
I tested TCP/IP connectivity by using ping command to ping : IP Address of local computer and remote computer, default gateway and DNS Server and it runs perfectly on both local and remote computer.
But when testing using WinRM commands, I used this command to locate listeners and addresses
winrm e winrm/config/listener
It gives me this output for my local machine
Listener
Address = *
Transport = HTTP
Port = 5985
Hostname
Enabled = true
URLPrefix = wsman
CertificateThumbprint
ListeningOn =<IP Address>,127.0.0.1, ::1,fe80::100:7f:fffe%13,fe80::803:5e43:50ef:c50%11
But the same command when I run on remote machine gives me an output with everything else the same, except
Listener[Source="GPO"]
.
.
.
ListeningOn=null
I want to configure it to make it listen correctly.
PART II
And when I run these commands one by one on my remote machine
winrm id -r:<machine name>
winrm get winrm/config -r:<machine name>
winrm get wmicimv2/Win32_Service?Name = WinRM -r:<machine name>
It gives a WSMan Fault with an error message as :
The client cannot connect to the destination specified in the request. Verify
that the service on the destination is running and is accepting requests.Consult
the logs and documentation for WS-Management service running on the destination,
most commonly IIs or WinRM. If the destination is the WinRM service, run the
following command on the destination to analyse and configure the WinRM service:
"winrm quickconfig".
Whereas, same commands when I run on my local machine run correctly.
winrm id
winrm get winrm/config
winrm get wmicimv2/Win32_Service?Name = WinRM
At most, all the problems I'm facing is on my remote machine.
What is causing this to happen and how can I configure it to listen and connect successfully?
Thank You.
Part II, I am now able to run these on one of my other remote machines with correct output.
I made some changes in this particular remote machine for which I had posted the question and so, it wouldn't run these commands until I fix the part I but besides that if nothing has been altered it will run just like it does on my other remote machines.
I would still appreciate if someone could help me with part I in which I have to get rid of
Listener[Source=GPO]
..
.
ListeningOn=null
when I run the command
winrm e winrm/config/listener
because this is what is causing issues but I'm not sure how to disable/remove Group Policy Settings.
To determine which group policy is configuring your WinRM you can run the following from an administrative command prompt:
gpresult /h result.html & result.html
In the displayed result, locate Windows Components/Windows Remote Management (WinRM)/WinRM Service. The Winning GPO is where you can enable/disable GPO settings. Use GPMC (Group Policy Management Console) to manage the Group Policy.
ListeningOn=null appears when an administrator has incorrectly configured the Group Policy IPv4 filter setting in Allow automatic configuration of listeners usually with an IP or network that does not exist on the affected Server.
To reset IP addresses (ListeningOn), you probably need to re-create the listener (remove the old HTTP listener and create a new one). Please find the example below.
In PowerShell:
Remove-WSManInstance winrm/config/Listener -SelectorSet #{Address="*";Transport="http"}
New-WSManInstance winrm/config/Listener -SelectorSet #{Address="*";Transport="http"}
Here is the syntax for the specific IP address to bind:
New-WSManInstance winrm/config/Listener -SelectorSet #{Address="IP:192.168.100.2";Transport="http"}
In Command Prompt:
winrm delete winrm/config/Listener?Address=*+Transport=HTTP
winrm create winrm/config/Listener?Address=*+Transport=HTTP

Related question: Allow PowerShell remoting only from one address.
I had the same issue and found that when the GPO Setting: Allow remote server management through WinRM had an IPv4 filter set to the IP address of my jumphost the winrm e winrm/config/listener command generated the ListeningOn=null issue.
I solved this by setting the Filter to * and sorting the permissions on firewall level instead.
I solved this changing a GPO, exactly as answered Neossian (sorry, no reputation to just add a comment). But "IPv4 filter" must not be empty, nor accepts CIDR notation (that was my huge mistake). As already said by Craneum, uses "*" for listen on any interface or some range of IP addresses your local network devices are connected (as "192.168.0.1-192.168.0.254" or something like that).
DO NOT USE "192.168.0.0/24" notation. Yes, the help section is very clear on that, yet I used the wrong notation.
The thing is that the IP Range you are entering is not the range that has access to the system but defines the IP range that can be used as the WinRM interface by the system. Means you have to specify a range of IP addresses which includes all the client IPs the GPO is affecting.
Ensure that you have a filter (IPv4 and/or IPv6) defined in the "Allow remote server management through WinRM" under [Computer Configuration]/[Policies]/[Administrative Templates]/[Windows Components]/[Windows Remote Management (WinRM)]/[WinRM Service].
I would suggest a filter of "*" for both IPv4 and IPv6 unless you know what you want to filter.
