    Have you made the host file entries on both server for each other ? I am not sure why, but this works some times.

    how can system can't reach to own.

    what do you mean by this?

    Are both instances on the same server?

  • there r two server

    1st one is primary server and

    2nd server are two instances (Mirror and Witness)

    both are running on two different ports, and both server in one domain controller.

  • Fully Qualified Domain Name (e.g. http://www.google.com)

    do you have Windows firewall enabled on the servers

  • windows firewall is disable on both servers.

  • Apply the most recent transaction log to your mirror server and leave it.If you get the same error to reapply again.

    windows firewall is disable on both servers.

    ok simple test, on the principal server go into administrative tools and open data source administrator. Create a new system DSN pointing to the mirror instance, at the end of the wizard click the test data source option and ensure it's successful

  • tomorrow i'll do it and get back to u for the same.

    i have not enable filestream. is any type of relation of both?.

  • May or May not be...

    Per BOL:

    Database mirroring can be used with the following features or components of SQL Server.

    •Log shipping

    •Full-text catalogs

    •Database snapshots

    •Replication

    Don’t find anything on FILESTREAM articles either way (accepting / rejecting).

  • Databases that have a filestream filegroup can't be mirrored, so if you haven't enabled filestream then you're fine to mirror that DB.

  • i mean to say, enable filestream for t-sql access in sql server configuration manager for sql server services.

  • Mirroring doesn't need any particular filestream setting. As I said, you can't mirror a DB that has a filestream column in it, so it would be a little weird if the filestream setting was necessary (it is not)
