we have problem with our Windows XP Clients when they access a file on a Netwareshare.

A user can open a file on a Netwareshare and after some time, when the user want to save the file or open an other file, the Windows XP clients hangs.
You only can power off the Windows XP Client.

These happens on different Clients. We have XP Clients with SP2 or SP3 and Novell Client 4.91 SP3 , SP4 and SP5.

Is there a way to get a logfile from the Netwareserver or has anyone an idear what i can do?

Kind regards
