I have two different Windows Sever 2008R2 instance located at different places such as db1 and db2. I need to make db2 as mirror server of db1 i.e. all the database on db1 will have a mirror copy on db2.

I tried setting it up using this link: but could not get through. The error I am getting is that while mirroring, it says that cannot locate the mirror server instance i.e. db2. I tried giving it using the IP address as well.

PS: Both the SQL Server instances are on different machines.

Any suggestions?

Are the two instances on the same domain? Is name resolution working correctly between the instances? – mrdenny Jan 4 '12 at 17:51
You've confirmed that you can reach each database on the port (I.E., "telnet db1 1433" from db2 and "telnet db2 1433" from db1) - assuming you're using the default TCP ports? – Kane Jan 5 '12 at 4:50
As, I have mentioned, they both are 2 diff Sql instances located on different servers all together. Such as one at and second one at 74.85.655.85 (samples not the exact one) – user5543 Jan 6 '12 at 5:26
have you tried all these suggestions from SQLAuthority ? – user5707 Jan 10 '12 at 13:29

If you cannot use the domain authentification (servers are not in the same domain), you need to configure outbound connections ( ) and inbound connections ( ) using certificates. I have tried this method, it's really works fine.


I would recommend to check the user you are using on both sql server instances (the one you're using to run the service) : it is easier to use the same domain user on both instance.
