  • Network Path Not Found Issue

    Hi,

    I have a smallish network with 2 servers;

    1st Serevr, Running Windows Server 2003 SP2, this is the DC.

    2nd Server, Running Windows Server 2003 R2 SP2

    I recently only added the 2nd server to the network and the domain about a month ago. Its is replicating the 1st servers AD. I have had no issuus with any of the servers untill 2 days ago when I installed FSRM on the 2nd server. Since then I have been getting on the 1st server the following error messages when logging into the server, and also when trying to reset passwords in the AD on the 1st server.

    Error Message When logging in: " No network provider accepted the given networ path"

    Error message when trying to reset a password in AD: "The network path was not found"

    Im not sure whats causing the issue, there is no error messages in the Event Logs.

    Is it possible that the 1st servers needs to run the ADPREP from the R2 disc to update the schema?

    Re: Network Path Not Found Issue

    Can you run DCDiag and NetDiag on the DCs?
    The schema already includes the R2 stuff if you have already got an R2 server so don't need to worry about that.

    How is your DNS setup on the DCs?
    cheers

      Hi Andy,

      1st Server is the DNS server and the 2nd server has the Ip address of the 1st server as its preferred DNS address

      Running dcdiag and netdiag on the 2nd server doesnt appear to work

      Running on the 1st server, results below;

          Re: Network Path Not Found Issue

          Do your switches support this?
          Adapter : Team #0 - Adaptive Load Balancing Mode

          Also, from reading below, are you saying you open ADUC and try to change a users password then get "The network path was not found"
          Does that happen on both DCs?

          Is DNS installed on both? Can you set each server to use the second DC as primary DNS and then itself as secondary then reboot each one individually (give it 10 mins or so after waiting for the first one to reboot).
          cheers

            Re: Network Path Not Found Issue

            Yeah the switch support this, I tried to disable the team, just in case and go back to a single NIC but the Intel PROset manager fails to load. (assuming this is related to the problem I'm having)

            Its only the 1st server that is affected. Yes in ADUC when trying to change a users password then I get "The network path was not found" error
            The 2nd Server can reset password etc no problems.

            Haven't tried the DNS yet

                    Hello,

                    I'm really glad you found answer to you problem but please as we have the same issue please kipkenyen post the fix

                    On our side DNS is fine directed to the server itself. DCdiag and netdiag are ok. Only 1 NIC on 2 activated and no other DC on the AD.
