xp pro messes up the network

You can try turning off the Browser Service on the other
machines (Right-click on My Computer, and select Manage,
expand Services and Applications, then click on
Services. Right-click on Computer Browser, and click on
Stop and set the startup type to Disabled.

Or you could edit the registry:
HKEY_LOCAL_MACHINE\System\ControlSet001
\Services\Browser\Parameters. Change IsDomainMaster to
FALSE, and MaintainServerList to No.

Repeat for ControlSet002.

Don't know if this will help, but it might be work a try.

Thanks, Jack

Our peer-to-peer network (containing my Win2000Pro
desktop
that shares the dsl internet connection and assigns IP
addresses to the other computers, seven 98SE desktops,
one
ME laptop, and one XP home desktop) works great, until an
additional XP Pro laptop is connected. Then all of a
sudden, the computer listing in the network neighborhood
disappears from every computer. We can still get around
the network either via mapped drives or via searching
for a
specific computer name. The XP pro laptop has no shared
files or folders. Why does it do this to our network?
