I want to start a New-PSSession without having to pass credentials in a script. I know you can get the password from a file or have it hardcoded in the script and then convert it to a secure string to start the session. However, I want to start the session using the current user's credentials.
The machine I am trying to remote to is in the same domain.
I tried:
Enter-PSSession -ComputerName machineInDomain
Enter-PSSession : Connecting to remote server failed with the
following error message : WinRM cannot process the request. The
following error occured while using Kerberos authentication: The
network path was not found. Possible causes are:
-The user name or
password specified are invalid.
-Kerberos is used when no
authentication method and no user name are specified.
-Kerberos
accepts domain user names, but not local user names.
-The Service
Principal Name (SPN) for the remote computer name and port does not
exist. -The client and remote computers are in different domains and
there is no trust between the two domains. After checking for the
above issues, try the following:
-Check the Event Viewer for events
related to authentication.
-Change the authentication method; add
the destination computer to the WinRM TrustedHosts configuration
setting or us e HTTPS transport. Note that computers in the
TrustedHosts list might not be authenticated.
-For more information
about WinRM configuration, run the following command: winrm help
config. For more information, see the about_Remote_Troubleshooting

I am trying to run a remote command to a computer which has a ".\".
When I am trying the credentials using get-credentials and storing them to a file, I am not allowed to do.

But when I do a mstsc and use the same credentials it works.
Please let me know the way around.
$env:COMPUTERNAME is your computer name!
Imagine I'm using ComputerA and wantning to connect to ComputerB as a local user on ComputerB.
Your code, as it currently stands is trying to connect as ComputerA\Username, which doesn't exist on ComputerB!
Can you try passing the username in below syntax?
$Username = -join('Localhost','\<user_name>')
I have two Windows 7 Pro systems, one host system and one in a VM one the host system. I am trying to create a New PSSession on the host system to control the guest, both of which run Powershell 4.0.
As we have a DHCP setup in the office the first thing I do is establish the IP adress of each. Then I run the code below on both machines -
Set-Item wsman:\localhost\client\trustedhosts "$relevantIP" -Force
I then test that the systems are ready using WSMan on the host -
Test-WSMan $remoteIP
wsmid : http://schemas.dmtf.org/wbem/wsman/identity/1/wsmanidentity.xsd
ProtocolVersion : http://schemas.dmtf.org/wbem/wsman/1/wsman.xsd
ProductVendor : Microsoft Corporation
ProductVersion : OS: 0.0.0 SP: 0.0 Stack: 3.0
All this works perfectly well. At this point I used to create a new PSSession using the following
$credObject =
$Host.ui.PromptForCredential(
"Need credentials",
"Please enter password for the following IP $remoteIP",
$remoteUsername,
""
)
$remoteSession = New-PSSession -ComputerName $remoteIP -Credential $credObject

I have no idea why it has started doing this when trying to connect to the VM from the host system. I can create a new PSSession on the host machine from within the guest but no longer the other way around.
The error message says that "Default
authentication may be used with an IP address under the following conditions: ... the destination is in the TrustedHosts list and explicit credentials are provided." I have already added the correspoding IP to each WSMan TrustedHosts fields and provide explicit credentials.
Any help would be greatly appreciated as I am scratching my head trying to think of what could be wrong.
Update
After following the suggestion of one commentor I tried using different authentification methods.
$remoteSession = New-PSSession -ComputerName "10.141.114.91" -Credential "Test" -ErrorAction Stop -Authentication Basic
The WinRM client cannot process the request. Unencrypted traffic is currently
disabled in the client configuration. Change the client configuration and try the request again.
So I ran set-item WSMan:\localhost\Client\allowunencrypted $true on both machines. Now trying to get a PSSession gives the error
Get-PSSession -ComputerName "10.141.114.91" -Credential "Test" -Authentication Basic
The WinRM client cannot process the request. If the authentication scheme is
different from Kerberos, or if the client computer is not joined to a domain, then HTTPS transport must be used or the destination machine must be added to the TrustedHosts configuration setting.
** Update 2 **
In case anyone has the same problem and comes across this - my problem turned out to be a combination of a network fault and then with my playing around somehow creating a list of IP addresses for wsman:\localhost\client\trustedhosts which missed a comma between IP's.
I’m trying to run a PowerShell script on SYSTEM1, which executes robocopy on SYSTEM2, copying files to SYSTEM3,4,5,etc.
SYSTEM1 and SYSTEM2 are on the same domain, but SYSTEM2 is not behind a firewall (hence the need to run robocopy from SYSTEM2 and not SYSTEM1).
SYSTEM3,4,5 are on different domains than SYSTEM2, as well as different domains than each other.
I set the script up like this (it uses the net use command to prompt the user for credentials for the different domains):
Foreach($server in $servers) {
$command = {
param($cred, $server);
$error.clear();
# Stored credentials in local variables
$user = $cred.GetNetworkCredential().username
$pass = $cred.GetNetworkCredential().password
#establish connection from SYSTEM2-> $server
net use \\$server\c$\Deployments /delete
net use \\$server\c$\Deployments /USER:$user $pass
# Check to see if C:\Deployments exists on server, and if not create it.
if ((Test-Path \\$server\c$\Deployments) -eq $FALSE) {
$c = {
New-Item \\$server\c$\Deployments -type directory
}
$ws = Invoke-Command -ComputerName $server -Credential $cred -ScriptBlock $c
}
# Copy over the deployment packages
$dest = "\\$server\Deployments\$DeploymentDate\$CurrentDirectoryName"
robocopy $CurrentDirectoryPath $dest /W:20 /R:15 /e /XF CopyPackage.ps1
# Delete connection from SYSTEM2 -> $server
net use \\$server\c$\Deployments /delete
However, the net use command returns an error after the credentials are entered:
The network connection could not be found.

I’ve read this could be a “double-hop” issue (as detailed here), but I’m not sure how to edit the script to use CredSSP instead of Kerberos (or if this is even the problem).
Any ideas?
Posting this solution in case someone is still having an issue with a simple resolution to DoubleHop without using CredSSP.
Try this out:
https://www.powershellgallery.com/packages/Invoke-PSSession
It Invokes a PSSession, then Registers a PSSessionConfiguration with the Credentials that you provided. Basically providing the credentials for that DoubleHop
Then use Invoke-Command with that new PSSession. It should have the required privileges to do what you need.
I am trying to open remote PSSession from one PC to another. Both PCs are in the LAN and reachable, but whenever I try to enter PSSession the following error occurs:
Enter-PSSession : Connecting to remote server pc2 failed with the
following error message : The WinRM client cannot process the request.
Unencrypted traffic is currently disabled in the client configuration.
Change the client configuration and try the request again. For more

ERRORs:
I was receiving the same problem when remoting to a server and found this blog post very helpful - http://jeffgraves.me/2013/10/14/powershell-remoting/
For my specific case I did the following:
On the Local machine
winrm quickconfig (although this was already configured)
winrm s winrm/config/client '#{TrustedHosts="myservername.domain"}'
On the Remote machine
enable-psremoting -force
Set-PSSessionConfiguration -ShowSecurityDescriptorUI -Name Microsoft.PowerShell -Force
I got around this problem by using a fully qualified logon. Instead of "netbiosdomain\accountname", I used fqdn\accountname, as in Microsoft.com\myaccount in the get-credential prompt. May not work for everyone, but it's worth a shot.
This is how I do it. I use this on my scripts.
# This is only done once
Read-Host -AsSecureString | ConvertFrom-SecureString | Out-File
c:\Windows\temp\securepass.txt
# Setup credentials
$SecureString = Get-Content c:\Windows\temp\securepass.txt | ConvertTo-SecureString
$mycredentials = New-Object -TypeName System.Management.Automation.PSCredential
-ArgumentList "yourDomain\userID",$SecureString
# Open remote session:
$MyRSession = New-PSSession -ComputerName Computer1 -Credential $mycredentials
-Authentication default
# Use remote session:
Enter-PSSession $MyRSession
Get rid of -UseSSL. I enabled PSRemoting and had problems with using that. I guess I could look at it later but for now it doesn't matter.
If there is no trust between the client and server computers, you have to enable basic authentication on the server side. Do this by toggling the correct properties on the WSMAN: drive on the server. You'll obviously have to do this interactively on the console or via remote desktop, due to the chicken and egg problem :) Also, this may come into play too:
http://www.nivot.org/blog/post/2009/10/30/PowerShell20EnablingRemotingWithVirtualXPModeOnWindows7
I was getting that same error currently no logon servers available.
The issue was resolved by using instead of Domain\Username as credentials the user UPN or Username#Domain.
I have achieved a remote session with Enter-pssession command, had to follow these exact parameters
$creds = get-credential (the -credential parameter in enter-pssession does not work properly, thus u must previously enter the object at another variable)
Enter-pssession -computername wsustest -authentication Default -credentials $creds
i Also had to set both client and remote server in the trusted hosts wsman: space
another solution which surely wouldve worked but i havent tried, wouldve been setting https: which is harder to do.
thx to all, your comments certainly led to the solution!
