Get a network trace in ethereal and look for lots of
GetPrinterData() requests. In the packet payload you will
see the string "ChangeID".  If this is your problem, then
isolate that client or two and run (on the client)

	net stop spooler
	net start spooler

Some drivers seem to trigger this behavior and sometimes
it seems to be independent of the driver used.

Are your XP clients running SP2 ?






cheers, jerry
