When you try to open a file through a network share by using the SMB protocol, the file may take a long time to open. This problem can occur when a Windows XP client also has the file open and owns the oplock to the file. It does not respond to the oplock break request, and because of this, the server waits until the request times out and the other client has to wait for that. Download now to prevent a possible request time out. For More Information - http://support.microsoft.com/support/misc/kblookup.asp?ID=309376 Download
