You might stumble on this one. I did.
I just added Powershell V2 on my Server 2008 Test environment at home. I should have EARLIER but again, I don’t typically need to run it on the server.
So I went to run the ENABLE-PSREMOTING command to trigger it off.
But it kept giving me an error, failing out every time. I checked and found the WinRM IIS extension was not added in my features list. So I added it in. No reboot was prompted.
Yet still it persisted. It seemed to have EVERYTHING set right (Firewall Exceptions, Services running)
So I tried the obvious. Even though the server DID NOT prompt for a reboot, I rebooted.
Next reboot ran the ENABLE-PSREMOTING command within Powershell.
Worked the second time about. I guess it DID need a reboot. Just something in case you encounter this.
