Using Terminal Services client to connect to the NS Server, we need to add the "/console" command line switch to prevent installation failures. No surprise there!
But I had some issues while with a customer (corrupt installation or strange behavior...), so I took a few minutes to make sure it wasn't 'my fault'.
I checked the server Terminal Services Manager Session ID, which should be 0 (zero) when connected in Console, and it wasn't!
Then I did
Start Run mstsc/?
As I'm running Vista, the /console is /admin
Nice try to confuse me ;o)
