We are running Enterprise client 8.66 (10) on windows 2000 pro sp2 with IE6. Many of our users are receiving explorer.exe illegal operations when browsing folders on shared drives. We have set windows to use classic view. We have tried pc with sp1 ie6, sp1 ie5, sp2 ie5, and sp2 ie6 without luck. The problem is intermittent we do have a few folders that cannot be opened on any win2k pc and the rest of the network drives it does not happen with any consistency. For example with in a 30 min period 10 people tried to open the same folder and for a 20 min none could open it. This problem even occurs when logged in with an admin id. Any Ideas???
