Exchange 2010 DAG update

23/06/2014 admin Exchange, News, 0

I had a problem with updating Exchange 2010 in DAG.

I resolved this in a such way:

1. Control panel – Internet Settings – Advanced – Turn off certificates checking.

2. Control panel – User accounts – Accounts control to minimum – OFF.

3. Check DNS settings – I had a small problem with it.

4. Run command prompt as Different user – the same you are login 🙂 with admin privilegues.

5. Move active DB to another server from powershell or UI.

6. Run C:\Program files\Microsoft\Exchange Server\V14\Scripts\StartDAGServerMaintenance.ps1

7. Run the update (if it will be unsuccessfully you have to reboot a server and start update again)

8. Reboot the server.

9. Run C:\Program files\Microsoft\Exchange Server\V14\Scripts\StopDAGServerMaintenance.ps1

10. Check the activation policy: Get-MailboxServer | fl name,databasecopyautoactivationpolicy (have to be unrestricted e.g.)
