WINRM
WINRM is the CLI interface to our WS-MGMT protocol. The neat thing about this is that you can call it from PowerShell to manage remote systems that don't have PowerShell installed on them (including Server Core systems and Raw hardware). I was trying some things out and encountered the following error:
PS> winrm
C:\Windows\System32\winrm.vbs(1034, 1) Microsoft VBScript runtime error: ActiveX component can't create object: 'WSMAN.InternalAutomation'
This is the second time that I've done something that made this problem come up. I'm working on a system that changes constantly so it is probably some side effect of something you'll never encounter. That said, I've run into it twice so I thought I would share the fix. This also documents the fix so if it happens to me again, I'll just use LiveSearch to find the solution J.
Run a PowerShell session with Admin Privs (I'm doing this on Vista):
PS> cd ${env:windir}/system32
PS> Regsvr32 WsmAuto.dll
PS> Regsvr32 WSManMigrationPlugin.dll
Do that and Bob's your Uncle.
BTW - you can do cool stuff with WINRM from PowerShell if you remember 2 things:
- You have to quote native code command switches that use ":"s
-
You can cast XML to [XML] and then party
