On a Windows Vista-based computer, you experience slow performance after you establish a VPN connection. Additionally, it may take several minutes to open a redirected shell folder. This problem occurs if the following conditions are true:

• Offline files are enabled on the computer.
• Some offline files are cached on the local computer.
• You logged on to the computer when you were offline.
• The VPN connection is based on a slow connection.

This problem usually lasts several minutes and then disappears.
