Remember to check the data / time in the upper right hand corner of the monitor listing.
Sometimes it gets...stuck ? and doesn't update as it should.
There will be times when I need to reboot a server for updates, etc. or what I like to call "mini-maint" that the services could be down for a little bit of time, but now that we've gotten the last real leg of our server move done, there shouldn't be any more issues regarding the Directory services, etc.
