Have you used resources like http://technet.microsoft.com/en-us/library/cc779704(WS.10).aspx or are you hoping to avoid that?
I am running Windows 2003 R2 on a Dell PowerEdge. I have a licence for a 5-user Terminal Services Utility so that remote users on my WAN can access the server. Unfortunately, I have been able to install only 1 user and I want to increase it to 5 users so that I can have a maximum of 5 users at a time. I need help to take me through the steps. Grateful for any help.
