When trying to view shared files across a network, this process can take up to 30 seconds for Windows to accomplish. The reason for this is; Windows spends this extra time is to search the remote computer for any scheduled tasks. If you would like Windows to bypass this search process, here's how:
Go to Start>> Run. Type in: regedit [Enter] or click OK
Drill down to the following registry entry:
HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/Current Version/Explorer/RemoteComputer/NameSpace
Click once on the "NameSpace" entry and find the following entry in the right pane:
{D6277990-4C6A-11CF-8D87-00AA0060F5BF}
Right click and delete this entry.
Note: Please be sure to export a copy of the Windows registry prior to making any changes to it.
