  • SBS2003 Unable to contact all domain controllers...

    I bought a new server, because my SBS server hardware is not stable anymore. I found a document to move/install sbs2003 on my new hardware.

    http://technet2.microsoft.com/Window....mspx?mfr=true

    I installed win2k3 without the sbs features. Then I moved all of the rolls to the new server and made it global catalog. Installed DNS, wich looks fine by the way. I promoted the server to be domain controller. After that I want to continue the SBS installation as it says in the document.

    First the installation gives a list of things to do/repair before setup can continue. Here I get the following error message:

    'unable to contact all domain controllers'

    My network contains the following dc's:

    1. the old sbs2003 server
    2. a windows 2003 R2 server
    3. the new sbs2003 server

    I tried everything to resolve this problem, but no succes! Could this problem has to do something with the R2 server?

    all the help is welcome! Thanx in advance!

    Hope you have all your data backed up.

    How did you install SBS 2003 without the SBS "features"?
    Without the SBS features how did you move the roles to the new server?
    Where does the old SBS 2003 server fit into your network?
    1 1 was a racehorse.
    2 2 was 1 2.

      To install SBS2003 without the sbs features, I canceled the installation as soon as it loads windows for the first time. The server run as a normal win2k3 server. It's the only way to join the server to the existing domain. After this the setup can be continued at any time.

      I tranfered the roles the normal way, after I promoted it to domain controller. Via the AD Domains & Trusts etc.

      The old SBS is only exchange server at the moment. This is the only thing that has to be tranferred now. To do that, I have to finish the sbs setup. The new SBS server will detect the old sbs server and will take over the settings.

      But the install will not continu untill I resolved the problem!

          Where does the Windows 2003 R2 server fit into this process? You mention in your first post that it is a DC. Was it a DC with the old SBS 2003 server or is it a new addition with the new SBS 2003 server?

            The R2 server was already a DC with the old sbs2003 server. When I promoted it, I first used "forestprep" on my sbs to prepare the active directory for this R2 domain controller.

            When I run dcdiag /v on the old SBS server it fails on advertising itself. He seems to pass the rest of the tests.

            My new sbs server seems to pass every test done by the dcdiag /v command.

            On my old SBS there is 1 error event logged today:

            Event ID: 1791
            Source: NTDS Replication
            Category: Replication

            Replication of Naming Context DC=IAgroep,DC=local from source 8ae83e8b-3fc2-461f-80e3-29bd6fd3779b has been aborted.
            Replication requires consistent schema but last attempt to sync the schema had failed. It is crucial that schema replication functions properly. See previous errors for more diagnostics. If this issue persists, please contact Microsoft Product Support Services for assistance. Error 8418: The replication operation failed because of a schema mismatch between the servers involved..



            Is it a good idea to demote the R2 domain controller, just in case?

              That's clear case of scema mismatch.

              Try this:

                I setup my servers in a VMware enviroment tot test the hotfix you gave me the link for. However when I install it, it indicates that there's allready a service pack on the machine that is newer then the hotfix. The hotfix can only be applied to servers without service packs installed.

                All my servers contain win2k3 SP2. So what can I try next?

                The only error that was logged in the event viewer is the event I posted yesterday:

                Event ID: 1791
                Source: NTDS Replication

                  Hi,

                  Please check the version of schema on all the DCs and let us know so that we can understand which DC is having the obsolate version of Schema......

                  To check the Schema version follow the below link:

                    Ok I will check that. Another thing that cought my attention is that my old sbs failed advertising as a time server.

                    What can I do about that?

                      Hmmmm.

                      Go to registry editor:

                      HKLM\System\CurrentControlSet\Services\W32time\Par ameters

                      Check for the "type" key it should be Nt5DS

                        I checked the schema version on all 3 dc's.

                        The two sbs2003 server have version 30. The R2 server has a newer version. This is version 31....

                        What to do next?

                        Thanx!
