Thanks Ronald,
You gave me a good clue where to start... I don't have the best infrastructure, I have a Win2000 Professional and a NT Workstation in the same workgroup.
Do I need MTS in both computers? I assume yes...
I turn off authentication for the system application in both computers but when I try to open the remote computer in the Console, I get the permissions error: "you don't have enough permissions, bla, bla
Any idea?
