Thanks for your response guys.
The scenario was out of the ordinary and not repeatable. I was changing between directories. It behaved strangely where it would block my access to folders that should not have been blocked. If I go up one level and come back down again, it would let me through. This happened several times. Or a simple thing such as going between folders, it would put up an hour glass when normally, that doesn't happen. It was odd and frustrating so I rebooted the server. Everything went back to normal after that. I didn't want to report it as a bug because it was not repeatable. I wanted to get some feedback from the field to see if anyone is having a similar experience. It could simply be the beginning of hardware failure. If this is what others have experienced that lead to imminent hardware failure, I want to prepare myself. Or perhaps there is a maintenance job that I should be aware of that is slowing things down. This happened 8:00pm.
Thanks.
