*Update*

The replacement of Summer is continuing. The final step of replication is taking longer than anticipated and is not expected to complete before 8:30AM.

Most systems will not be affected by this as the other 3 Active Directory servers are running. If you believe your system is affected and need support in changing your AD or DNS settings please contact the IT Support Center x36666.

This notice will be updated when the server upgrade is complete.
