I have two servers, one in the Portsmouth, NH datacenter, one in the Kansas City datacenter, same domain.
Trying to set up mirroring. First, does it matter that one server has Windows 2008R2 server and the other has 2012R2 server on it?
Have opened the firewall ports between the two servers, can
telnet back and forth between the two.
Go through all the mirroring steps and get the generic Microsoft error:
The server network address "TCP://--------.lm.lmig.com:15025" 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)
The SQL Server version is 2008 SP3 Standard Edition.
