Novell 3.12 and Windows 98

We’re using Novell 3.12 on file server and some computer have Windows 95 and Windows 98 OS. My problem starts when i want to share my resources, it says “You cannot view the list of users at this time. Please try again later”.
Upon checking network properties, it says that i have the right server name.
Pls enlighten this issue.

Thank you.
