Groupwise has been working fine and is on a Netware 6.5 sp7 server. We added a new Windows 2008 server (reluctantly) and now some, but not all, users get occasional 8201 Errors when using Groupwise client. Only think I can think of is the IP address for the new Windows server DNS is added to the workstation DNS lists. Would that throw off Groupwise? Any other suggestion?
