When you try to log on to Terminal Server, you receive the followingerror message:
User Environment The operating system was unable to load your profile. Please contact your Network Administrator. (203)
The dialog box gives you 30 seconds to read the message. Then, itcloses the connection to the Terminal Server. Selecting the OK button onthe dialog box also disconnects the session to the Terminal Server.
The Application Log on the Terminal Server records an Event ID 1000. Thesource is Userenv. You get the same message that you are shown when you tryto connect.
The Terminal Server's registry quota has been exceeded. As each new userlogs on to the Terminal Server, your ntuser.dat from your profile is loadedinto the Terminal Server's registry. If several users are logged on to theTerminal Server at the same time, it is possible that the default value forthe computer's registry quota can be exceeded.
The System Log in the Terminal Server's event log will show an Event ID 26,which indicates that the system is running low on registry quota.
To remedy this situation, start the System utility in the Control Panel andselect the Virtual Memory button to increase the computer's registry quota.
