Import-PSSession : Proxy creation has been skipped for '%' command, because PowerShell couldn't verify its name as safe

Question

I have a Sharepoint farm setup and I'm connecting to one of my application/search servers from a Windows 7 machine in the domain using remote powershell. Both the client and application servers have powershell 2 with the execution policy set to unrestricted and psremoting enabled. Additionally, i'm running the cmdlets as a domain administrator account.

I can create a session to the remote server using the following cmdlets:

$Session = New-PSSession -ConfigurationName "Microsoft.PowerShell" -ConnectionUri "http://app01-spl1:5985/wsman/" -Authentication "Kerberos" 
Import-PSSession $Session -AllowClobber

However, When I Import the session I get the following eror:

Import-PSSession : Proxy creation has been skipped for '%' command, because PowerShell couldn't verify its name as safe.
At line:1 char:17
+ Import-PSSession <<<<  $Session -AllowClobber
    + CategoryInfo          : InvalidData: (:) [Import-PSSession], InvalidOperationException

    + CategoryInfo          : OperationTimeout: (:) [Import-PSSession], ArgumentException

Can anyone help solve this error?

Answer 1

I resolved this by simply entering the remote session instead of importing it. I was then able to add the SharePoint snap-in installed on the remote machine and run my script.

$Session = New-PSSession -ConfigurationName "Microsoft.PowerShell" -ConnectionUri "http://app01-spl1:5985/wsman/" -Authentication "Kerberos" 
Enter-PSSession $Session
Add-PSSnapin Microsoft.SharePoint.PowerShell

<Cmdlets or script goes here>

Exit-PSSession
Remove-PSSession -ID $Session.ID
[GC]::Collect()

Another option is to use Invoke-Command cmdlet with the ScriptBlock parameter like so.

$Session = New-PSSession -ConfigurationName Microsoft.PowerShell -ConnectionUri "http://app01-spl1:5985/wsman/" -Authentication Kerberos
Invoke-Command -Session $Session -ScriptBlock { Add-PSSnapin Microsoft.SharePoint.PowerShell }

Invoke-Command -Session $Session -ScriptBlock { <Your cmdlet here.> }

Remove-PSSession -ID $Session.ID
[GC]::Collect()

Answer 2

The error is that you are trying to import the entire set of commands from your remote server. Not quite sure why you are allowing clobber.

Personally, I'd just import the relevant SHarePoint module(s) rather than all of the remote workspace.

Does the import work??
