Urgent help on Sql server connectivity

  • Here is the problem I am facing..

    From Machine A I am able to connect to Machine B using either the instant name or IP address.(using Management studio)

    But from Machine A, I can only connect to Machine C using instance name.

    When I checked the setting for Machine B with Machine C , I found no difference.

    Also, firewall is turned off and all the setting in configuration manager is same in both machine. How come I can connect to Machine B with either ip address or instance name but not the same with Machine C.

    I need to connect to Machine C with ipp address as I need to remotely work through VPN connection.

    Any help on this is greatly appreciated….

  • Is C a default instance or a named instance? If it is named, do you have the SQL Browser service running?

  • Machine C is a named instance. However the default instance does not exists any more on the machine.

    The configuration manager has info only for the named instnace and not for the default isntance.

    I have checked the configuration manager for Named instance and SQL Server browser is running.

    Looking forward for your response...

  • THANKS FOR TRYING TO HELP. i GREATLY APPRECITE IT. i COULD RESOLVE THIS PROBLEM.

    I was not refereing the named instance server properly.

    Instead of refering it as 123.XXX.XXX.XXX\MachineC, I was refering it as MachineC

    I was excluding the IP address..

  • Try connecting by providing the ip address with the port as server:port. The port can be obtained from the configuration manager -> protocols -> TCP - I assume this is how you are connecting.

    Presumably you have already confirmed that machine C is on the IP address you think it is.
