The Alter Database Command Could Not Be Sent
DATABASE command could not be sent to the remote server instance TCP://%witnesserver.fqdn.com:5022. Error 1456 Found a fairly recent fix for SQL 2008 (r1) for this, but not for R2. Is this still a known problem in R2 or am I missing something crucial? All the servers use the same service account for all services (it's proof of concept, not production). Thanks in

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 the witness alter database citec_vc_prod set witness = 'TCP://witness_address:witness_port'; I get the following error after a few seconds: 2012 error 1456 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. Please help me SQL server gurus, you're my only hope! Edit: Here's a complete log of the T-SQL commands I used to set up mirroring. Once the first attempt failed with the problem described above, I deleted everything and started from scratch. The same problem reoccurred though. -- PRINCIPAL create master key encryption by password = 'mypassword'; GO create certificate "server1.ourdomain.com_cert" with subject = 'server1.ourdomain.com certificate', start_date = '2007/11
