SYMPTOMS

When you try to log on to a Windows Vista-based computer or a Windows Server 2008-based computer, the logon process may take a long time because of incremental network traffic.

This problem occurs when you have large number of offline files on the computer.

To determine whether you are experiencing this problem, open a network monitor tool. Then, stop and restart the Windows Search service. If you notice lots of network traffic, you are experiencing this issue.

CAUSE

This problem occurs because, by default, the Windows Search service is configured to index the client-side cache (CSC) in Windows Vista and in Windows Server 2008. During the system logon process, the FindItem and ItemExists methods of the IOfflineFilesCache API request the index of the offline files from the remote server. This behavior causes lots of network traffic.
