two instances on one m\c for Mirroring.... Is this the issue?

  • While mirroring setup I get following error:

    An error occurred while starting mirroring.

    Alter failed for Database 'AdventureWorks'. (Microsoft.SqlServer.Smo)

    The server network address "TCP://LuckyPC.American.Ccp.microsoft.com:6677" 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)

    How to troubleshoot this issue? How to verify whether this port is free or not?

    Infact For mirroring setup I am using two instances on one m\c. Is this required to have two different m\cs?

  • There is following information from the sql server profiler:

    2009-09-24 21:10:10.87 Logon Database Mirroring login attempt failed with error: 'Connection handshake failed. There is no compatible encryption algorithm. State 22.'. [CLIENT: 172.12.138.108]

    Perhaps this shows that I don't have correct logins. I shall create same sysadmin in both the servers and then try again.

    But I am using windows login in both the instances. I am using both of these instances on one m\c. So this error is unlikely because of same sysadmin login in the master DB of both the instances.

  • There is some information on following link

    This looks relevant but should I need to reinstall the sql server as the auther of this article did :(?

    How to completely drop previous mirroring?
