I'm using Windows 8.1. and I'm trying to execute commands on another Windows 8.1. by using PowerShell (enter-pssession or invoke-command). I usually have two types of error messages : one telling me that the access is denied and another one telling me that my Firewall does not allow an HTTPS exception. None of the computers is a server. I have already tried executing Set-PSSessionConfiguration -ShowSecurityDescriptorUI -Name Microsoft.PowerShell without any result whatsoever.
I have already tried de-activating my firewall and have already added other computers to my list of trusted hosts.
I always put an IP address after enter-pssession. Could this be the source of the problem?
Thanks in advance :)
P.S. Both computers have winrm, IIS and Apache.
All you need to get started with remoting is available in the help:
PS> Get-Help about_Remote_TroubleShooting -ShowWindow
If you're not in a domain, take a look at this section:
HOW TO CONNECT REMOTELY FROM A WORKGROUP-BASED COMPUTER
-------------------------------------------------------
[..]
When the local computer is not in a domain, the following procedure is required
for remoting.
1. Configure the computer for HTTPS transport or add the names of the
remote computers to the TrustedHosts list on the local computer.

I set up the remote development over SSH from my windows 10 machine to one of our new Windows 2022 servers. This due the fact that I need to use an other account with extra permissions to be able to run the script on the server.
Everything works fine, I can do 'remote development' over SSH with the other account and write & test powershell code on the server.
When I try to contact an external source in my script (like a fileshare or SQL), I noticed the dreaded "Double-hop" problem pops up.
As the first hop is SSH and not a real WinRM session, I thought this wouldn't be a problem?
Can I force VsCode/Powershell to not see the SSH connection as the first hop?
Or is this something Microsoft changed/enforced for security reasons?
By the way, I'm using Powershell 7 on both client and server
Whether SSH or WinRM, it's the OS on the first jump box that knows this is a remote session. If you want to be able to pass credentials off to a second box you'll need to look into enabling CredSSP.
To enable on your Windows server:
Enable-WSManCredSSP -Role server -Force -ErrorAction Stop
This should then allow you to access secondary servers. We do this to support a number of things; example: remoting into box A, and making box A grab some software from box B to do an install.
Always disable CredSSP afterwards:
Disable-WSManCredSSP -Role server -ErrorAction Stop
We have 7 Terminal Servers, and for some reason, I can only use Invoke-Command on those two, when the domain administrator is logged on to the servers.
I will get this error, when I try to use Invoke-Command on them, when the domain administrator isn't logged on to them. The other 5 servers have no issue.
As soon as I log in with the remote administrator, it works flawlessly.
[RDH004] Connecting to remote server RDH004 failed with the following error message : The WSMan service could not launch a host process to process the given request. Make s

I did doublecheck if the service Windows Remote Management (WS-Management) was running. And I did create a GPO (Allow remote server management through WinRM) to allow remote connections.
Did the same thing, on all servers to attempt to enable it. All servers are a clone from the same template in ESXi. And all servers are running Windows Server 2016.
I've searched far and wide for solutions, but none of the solutions seem to be the same problem. Especially not, since it works if the server I'm trying to send a remote command to, has the domain administrator logged in.
The cause of this issue is due to the Windows User Account Control (UAC). The remote account must be a domain account and a member of the remote computer Administrators group. If the account is a local computer member of the Administrators group, then UAC does not allow access to the WinRM service. This error happens even if the account is a Local Administrator and the command line is run with administrator privileges.
To solve the problem, UAC filtering for local accounts must be disabled by creating the following DWORD registry entry and setting its value to 1:
[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System] LocalAccountTokenFilterPolicy

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 quite new to PowerShell and am trying to write a script that connects to our web server from our db server and pulls a file across. Unfortunately I'm hitting hurdles straight out of the gate with the following error when trying to use the Enter-PSSession cmdlet:
http://imgur.com/jzpmV6z
I can confirm that PowerShell on the web server is set up and ready to receive connections:
http://imgur.com/o3g4bxK
I am at a loss as to what to check now. Any help would be greatly appreciated.
EDIT: Just to confirm, I am able to RDP into the web server from the db server fine.
If you are not using domain joined Machines and domain user accounts you will need to add the destination server to your trusted hosts list
Set-Item WSMan:\LocalHost\Client\TrustedHosts\ -Value "192.168.100.234"
You should check if you have machines add first
Get-Item WSMan:\Localhost\Client\TrustedHosts
if you do you will need to append the new ipaddress or the pervious values will be overwritten.
You should also check the network profiles on both machines. Powershell remoting will not work with the network profile set to Public.
EDIT:
You need to run: Enable-PsRemoting not winrm qc to allow powershell remoting
winrm is only half the puzzle.
Hello. dont Have a reputation to post a comment, so read some info
heare. If you have a domain you can try to do this: In the group
policy mmc: Policies/Administrative Templates /Windows
Components/Windows Remote Management (WinRM)/WinRM Service
Allow Remote Server management through WinRM
Set the Policy to Enabled.
Set the IPv4 and IPv6 filters to *
enter link description here
Or you can try to do something like this:
On local host and remote PC
Set-ExecutionPolicy remotesigned -Scope CurrentUser -Force| Out-Null
winrm qc -q| Out-Null
