All Forums SQL Server 2005 Forums High Availability (2005) Witness problem - error 1456 Reply to Topic Printer Friendly Author Topic wirtz Starting Member 2 Posts Posted-11/27/2008: 05:28:36 Hello,I have problems to add a witness to my mirroring session.Principal and mirror are https://support.microsoft.com/en-us/kb/2276717 in one domain, witness is another domain. I figured out that I have to use certificates to do the mirroring session.I followed the instructions on msdn... the mirroring itself (principal/mirror) works fine, but when I want to add the witness I get into trouble.I did as the instructions on msdn said: configured the witness for in- and outgoing connections, imported certificates, added logins and users for principal/mirror on the witness and vice versa.I http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=115288 have checked the ports via cmd -> "telnet xx.xx.xx.xx port" and there is no problem connecting on the port used for the endpoints in any direction.But when I run transact sql on the principal to add the witness I always run into an error.ALTER DATABASE db1066xxxxx SET WITNESS = 'TCP://88.xx.xx.xx:5022'the error 1456 occurs:The ALTER DATABASE command could not be sent to the remote server instance 'TCP://88.xx.xx.xx:5022'. The database mirroring configuration was not changed. Verify that the server is connected, and try again.I can definitely connect to the server... telnet works fine and I can even load the witness in the management studio on the principal/mirror... so: what is really the problem?I have already checked several forums and instructions on the internet, but couldn't find a solution... Thanks for your help.

I've set up everything as described at this blog post Mirroring seems to work fine between the principal and secondary server. But when I run the very last command to add 2012 error 1456 the witness alter database citec_vc_prod set witness = 'TCP://witness_address:witness_port'; I get the following error after a few seconds: Msg 1456, Level 16, State 3, Line 1 The ALTER DATABASE command could not be sent to the remote server instance 'TCP://witness_address:witness_port'. The database mirroring configuration was not changed. Verify that the server is connected, and try again. Also, the event log on the principal shows the following error: The ALTER DATABASE command could not be sent to the remote server instance 'TCP://witness_address:witness_port'. The database mirroring configuration was not changed. Verify that the server is connected, and try again. I've already shut down the firewall on the witness, and I've successfully telnetted from the principal into the mirroring endpoint of the witness server to make sure there is no connectivity problem. Yet, I still get this error. My setup is as follows: Principal: SQL Server 2008 R2 Standard 10.50.1617 Mirror: SQL Server 2008 R2 Standard 10.50.1617 Witness: SQL Server 2008 R2 Express 10.50.2500 Each of the servers is in a different workgroup.
