SYMPTOMS
When you try to open a file through a network share by using the Server Message Block (SMB) protocol, the file may take an unexpectedly long time to open.



CAUSE
This problem may occur if a Windows XP client also has the file open and owns the oplock to the file. In this scenario, the Windows XP client does not respond to the oplock break request. Therefore, the server waits until the request times out, and the other client must wait for this timeout process to complete.



Service Pack Information
