I am trying to connect with "Administrative Tools>Computer Management" on a remote Vista (Enterprise) machine, the connection is established successfully but when i try to enter on "Device Manager" it fails with the error: Unable to access the computer AVISTA. Make sure that this computer is on the network, has remote administration enabled, and is running the "Plug and Play" and "Remote Registry" services. The error was: Access is Denied. Both services are running, connected with valid credentials. I would gladly appreciate any advice. Thanks.
