I am trying to familiarize myself with the runas command so I can do my IT work more efficiently. I am experimenting at home on my windows xp pro machine that is part of a workgroup. Right now, my issue is that when I try to run control panel or control admintools using the runas command, the cmd window pops up, asks me for my password, says it is attempting to open my choice, but never does. The hourglass shows for a moment, then disappears. I do have the secondary logon service running, it starts automatically, and I verified I can do this in the administrator account to see if my syntax was that far off. I also opened the command prompt using the runas command. I tried the same from within that window, and still control panel or administrative tools will not open. Has anyone encountered this and found the problem? If you could help me identify the problem I would greatly appreciate it.
