Thank you, Boss. I have tried in the way you mentioned. In configuring mirroring I left service accounts box blank. But when I click on Start Mirroring, I get an error message something like "The server network address “TCP://SQLServer:5023? 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)"

I can not get the problem. Please help me.
