"No network provider accepted the given network path"

    Hi there

    Here is my network configuration: 2 x 2003 DCs, serveral 2003 member
    servers. All running SP1. Exchange Server 2003 (SP1) running on 2003 server
    (no SP).

    When trying to connect to Exchange Server via UNC (start | run |
    \\servername) from one of the DCs I get the error message "No network
    provider accepted the given
    network path". This even occurs when I do the start | run on the mail server
    itself. I can ping the mail server via ip, host name, and can do nslookups.

    If I try the same thing from a workstation I get "the network path was not

    The server is not visible in the network browse list any longer. Server
    itself is operational, and email delivery is not affected.

    The Exchange server is a DHCP client with client reservation.

    No other servers are affected. The problem will temporarily go away when
    rebooting the server, but will reoccur after a few days.

    I have scanned for viruses and malware, and had the virus checker disabled,
    but no difference.

    I use only DNS for name resolution. No hosts or lmhosts files, no WINS.

    No error messages in the event logs on either DCs or the mail server.

    I initially logged this in the Exchange Admin news group, but have been told
    that I was barking up the wrong tree, and should try a general Windows Server
    group instead, and here I am.

    I am at a loss. Any suggestions anyone?

    Many thanks

    Hello - I followed you here from the Exchange group because I thought of a
    coupla other things......
    You might post an unedited ipconfig /all from the Exchange server, and also
    from one of the DCs where you're having this issue.
    That's where WINS comes into it (you really do want WINS - even beyond
    browsing, Exchange just likes it.). You can't browse network neighborhood
    without NetBIOS over TCP/IP and you don't want all your computers competing
    to be master browser. Install and configure WINS....and set up all clients
    and servers to point at that server's IP.
    I'd use a static for all servers if it were me.
    Are you sure the server is updating itself in DNS properly?

    I'm not stalking you, honest! I'd have mentioned this stuff earlier but I
    was in auto-pilot mode.
