Posted on 2006-04-10

I have a windows 2003 which is part of a domain(main server is windows 2000). We are using some software(winfax) to connect to winfax windows 2003. It has been working for one year or more now we are getting The RPC server is unavailable when I try to connect to windows 2003 server. I cant seem to find anything we did on that server.
Btw I tried connecting from windows 2000 and windows XP work station also as administrator

    Any chance the Windows firewall has been enabled on the 2003 server?

    -Right click on Network connections and choose properties
    -right click on your network adapter/s and choose properties
    -click on the advanced tab, and then settings
    -should be checked on or off

    Firewall didn't exist until service pack 1. If you don't have that update it will not be present. If enabled try disabling to see if it resolves your problem. You can then re-enable if you like, and set "exceptions" to allow the services you need.

    If that doesnt help, you can try this:

    1. Click Start, click Run, type the following line in the Open box, and then click OK:
    net start rpcss
    Test to see if this resolves the issue. If the issue still occurs, continue to the next step.
    2. Click Start, point to Programs, point to Accessories,and then click Command Prompt.
    3. At the command prompt, type ping servername, where servername is the server, NetBIOS, DNS, or GUID name that you want to test for connectivity.

    If there is a connection issue with one of these computers, contact your network administrator to resolve the issue. If the issue still occurs, continue to the next step.
    4. Use the Netdiag tool that is included in the Microsoft Windows Support Tools (included on the Windows CD-ROMs) to determine if the domain controller is working correctly. You can perform a network trace using the MSRPC, DNS, NBT, LDAP, or TCP protocols.

    If there is an issue with the domain controller, contact your network administrator to resolve the issue. If the issue still occurs, continue to the next step.
    5. Use the Netdom tool that is included in the Windows Support Tools to verify network trust relationships and reset or establish a connection to a server.;en-us;Q224370
