Setup issues with mirroring (2008 r2)

Posted on 2013-01-24

I am trying to set up high performance mirroring between a primary server (ps1) and a secondary server (ss1)

When i tell the mirroring to start, the following error appears;

TITLE: Database Properties

An error occurred while starting mirroring.


Alter failed for Database 'Sue_Test'.  (Microsoft.SqlServer.Smo)

For help, click:


An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)


The server network address "TCP://<SS1<.<domain>.local:5022" can not be reached or does not exist. Check the network address name and that the ports for the local and remote endpoints are operational. (Microsoft SQL Server, Error: 1418)

For help, click:



I have checked that the ports are enabled, checked that I can see the SS1 from PS1 and have checked that the account that starts the services on each side has permissions.

Please can anyone advise me what else I need to do?

What type of Authentication are you using? Are you using Windows authentication or SQL authentication for the mirroring endpoint?
How did you set it up - using the wizzard?

I have literally just managed to get it to work :-)

Turned out that the account running the services didnt have the right permissions on the instances.

Dopey mistake not to have already checked - I was so busy checking that I had the correct user named that I didnt think about the actual permissions assigned!

Thanks lots though

Ive accepted my own solution simply because I worked it out before I was given the answer - it was just permissions that I hadnt thought to check
