By default, Win2000 will attempt to access the remote scheduler service on remote computers such as Win95, Win98, and Novell Netware. This can cause long delays of over 30 seconds while futilely attempting to access the remote service. This was scheduled to be fixed in SP2, but was not. Use the Registry File below to delete this key, which will disable this feature.
