Alter failed for Database 'DBNAME'. (Microsoft.SqlServer.Smo), The server network address "TCP:/win.abc.com: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)

Solution :-
========

1. Change the SQL Server Service Accounts and Agent Accounts to domain accounts.



2. Once this is done, start Mirroring.

3. To check the endpoints.

SELECT name, protocol_desc, port, state_desc FROM sys.tcp_endpoints

WHERE type_desc = 'DATABASE_MIRRORING'
