** Maintenance Announcement – No service interruption anticipated **
Services Maintained & Purpose of Maintenance: On Thurday we started getting replication errors on one of the NWS domain controllers. We determined that there corruption on one copy of the Active Directory databases. The server, NWS-DC1, was a global catalog server so we removed it from the round robin rotation for GC.NWS.oregonstate.edu and then removed the GC role from the server. This didn’t solve the database corruption so on Friday we promoted a new server as a domain controller to restore redundancy. On Friday at 5:30 we demoted NWS-DC1 as a domain controller, ran disk diagnotics, patched and rebooted it. We then re-promoted the server and verified that the AD database was healthy and replication was successful. After the GC role was restored we again verified that the server was healthy and placed it back into the round robin rotation as gc.nws.o.e. At about 10:30 pm we received a report that the virtual user script was slow to complete so we removed the server from the rotation until replication traffic settled do wn and the script completed in a timely fashion.
