Symptoms
A Microsoft Office Communicator client has been given control of a remote Windows-based client computer during a desktop-sharing session. However, when the Communicator client is prompted for the administrator credentials that are required for User Account Control (UAC) security, the operation fails. This issue occurs when the Windows-based client computer is running one of the following operating systems:
- Windows 7
- Windows Vista
The Communicator client cannot obtain the administrator credentials that the UAC feature on the shared client computer requires for administrative access to the protected areas of the Windows-based client operating system.
Workaround
To access the UAC-protected operating system components of a Windows-based client computer, use the Windows Remote Assistance feature.
