When you connect to another computer with Windows XP, it checks for any Scheduled tasks on that computer - a fairly useless task, but one that can add up to 30 seconds of waiting on the other end - not good!

Fortunately, it's fairly easy to disable this process.
First, navigate to:
HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/Current Version/Explorer/RemoteComputer/NameSpace in the Registry.

Below that, there should be a key called {D6277990-4C6A-11CF-8D87-00AA0060F5BF}.

Just delete this, and after a restart, Windows will no longer check for scheduled tasks - mucho performance improvement!
