We installed Novell Client 2 SP2 IR3 on both our Vista and Windows 7 machines, and everything appeared to be running great, but I have come across an odd behavior on our Vista machines. They log on fine initially, and can see the tree, change context etc. If the machine resumes from standby or hibernate, they cannot see the tree even if you wait a minute or so before logging back in. I've even waited 10 minutes, just to see it never will, and rebooting the computer does not always fix the issue. There is no antivirus or firewall on the machines currently. Any help is appreciated.
