An environmental issue in the McNichols Server Room occured @ 12:20PM, which in turn took out part of the TITANNET Home & Group drive services. We had to rebuild one server which may have affected your connectivity to these shared drives. The domain is back up and stabilized.
If you notice a red X on your shared drive, you should be able to double-click on it and connectivity should be restored. Otherwise you will need to reboot your workstation and log back on.
