Faster access to network PC's

I found some thing interesting so here it is when you try to access a computer on a network by its name some time it takes a long time to show the shared files
instead if you open
‘\\computername\foldername’,it opens immediately.probably this occurs when a Windows 2000 system tries to access a Windows 98 system. Thesystem tries to read the scheduled tasks of the remote system—a fairly uselessstep. To solve the problem, open the registry and delete the HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\RemoteComputer\
NameSpace\{D6277990-4C6A-11CF-8D8700AA0060F5BF} key.
