The domain controller summer.ad.queensu.ca will be undergoing a hardware upgrade on Wednesday March the 9th from 5am to 6am. Systems and Applications that use solely Summer for DNS name resolution and/or AD authentication will experience issues during this time.

To mitigate issues, application administrators can modify their authentication settings to use one of the other 3 domain controllers, qu-ad01-prd, Spring or Winter.

This notice will be updated when the upgrade has been completed.

If you have any issues or concerns with this upgrade, please contact the IT Support Center x36666
