  • Unable to access the SBS 2003 server/Domain Controller

    Problems:
    Workstations are configured for DHCP but cannot get an IP address from the SBS Server/DC.
    Can't remote desktop to SBS/DC
    Can't access shares on SBS/DC (ABCSBS01)


    Environment:
    Vista SP1 & XP SP2/3 PCs,
    Win 2003 SBS Server SP2 with Exch, DC, DNS & DHCP (SBS/DC) (ABCSBS01) (192.168.0.2).
    Win 2003 File Server, also a DC (192.168.0.3).
    No Windows Firewall.
    Cable Modem Ė DHCP disabled
    Smoothwall firewall (192.168.0.1)

    Connectivity:

    PCs
    Vista PCS attempt to log on to the SBS and get a 169.254.*.
    Network Diagnostics give Windows cannot find ďABCSBS01Ē Click for more information about DNS.
    Ipconfig /displayDNS, Name does not exist appears in relation to all the DNS servers
    The domain name abc.local is visible in DHCP Scope 006
    Have done Ipconfig /flushDNS, Ipconfig /degisterDNS
    When attempting to access email on the exchange server Gets error "Microsoft Exchange server is unavailable appears. Retry/Work offline/Cancel". Cant access SBSDC shares
    Can remote desktop to the ABCFS01 File server but not to SBS/DC ABCSBS01
    Pings to the SBS/DC Ė via IP address or workstation name give time-outs,
    When doing NSLookup <DC name> we get a DNS request timeout with Server UnKnown however the Ip address of the DNS server is returned.


    SBS/DC (ABCSBS01) Ė Connectivity & other
    Can ping itself via w/station name (ABCsbs01) or IP address (192.168.0.2)
    Can ping PCs & file server (but pings from those PCs to this DC timeout)
    Can access the File server file via Remote Desktop and can access files & folders on the file server (ABCFS01) and internet
    DHCP Ė services are started & authorised. The only entries in the DHCP logs are events 24 & 25. Scope Option 15 has abc.local specified in the value and 192.168.0.2 is specified in scope 006 (DNS Server) & 044 (Wins/Netbios).
    Net Logon services are started
    ISA is not installed on the network.


    DNS Setup

    Have done, Ipconfig /FlushDNS, Ipconfig /RegisterDNS, DCDiag /FIX, Net stop netlogin, Net Start netLogin.
    DCDiag gives error GUID <Long Number>._msdcs.jsr.local) couldn't be resolved, the server name (jsrsbs01.jsr.local) resolved to the IP address (192.168.0.2) and was pingable. Check that the IP address is registered correctly with the DNS server. ABCSBS01 failed test Connectivity
    Other DCDiag tests pass.
    We have looked through the event logs and havenít found anything that looks particularly informative.


    Where else do we need to check/look to overcome the login problem which I believe is preventing access to the Exchange mail or shares on the file server.

    IPConfig results are following this post

    Any help would be appreciated.

      First correct your DNS server settings. This is incorrect.
      You can find a lot of it here on the forums.

      However this is not the issue why you aren't getting a IP address.
      Disable IPv6 on the client and re-run ipconfig /release and then ipconfig /renew.

      Make sure that the DHCP server is enabled, autorized and up and running.

        Re: Unable to access the SBS 2003 server/Domain Controller

        Hi Marcel,

        Thanks. I deselected the V6 IP and also removed the external (ISP) IP addresses from the DNS settings of the workstation so just the local DNS Server Ip is there. But I still cannot connect to it.


        When doing ipconfig/renew I get the error " An error occurred while renewing interface Unable to contact your DHCP server. Request time out.

        DHCP is running and authorised. It is the only DHCP server on the network. When I look at the statistics on it, it shows Nil Discovers, Offers, Requests, Acks, Nacks, Declines etc.

        The DNS server also passes the database consistency checks.

        It also seems odd that when I set a workstation a fixed IP of 192.168.0.*, I still cant ping the SBSDC or remote desktop to it. But I can ping that worksation from the SBSDC and remote desktop from the SBSdc to another wokstation.

        The recursive and simple DNS tests pass.

        What other tests are there for the DHCP server?

            Hi Marcel,

            Windows firewall on the SBSDC is turned off. There is no other firewall on it or on the other server. The firewall is actually the network gateway/Smoothwall box 192.168.0.1

              These are Vista workstations, right? Are they members of the domain? Were they joined by using http://abcsbs01/connectcomputers ?

              Have you used MU (Microsoft Update) to download all patches to the SBS? There are some special ones specifically designed to update SBS to allow Vista to join correctly and fully.
              TIA

                Hi Steven,

                Both Vista & XP PCs. From recollection they were either joined to the domain via their initial setup - (join domain or workgroup) or from AD. Until last week, they were all functioning correctly.

                Windows firewall is turned off and I looked at Group Policies. None were enforced or configured, but I disabled SBS firewall in the GP Management.

                  So let's step back and see what has changed since last week. Patches? Drivers? Configuration?

                      Thanks. I now have. It pointed me to an article (MS KB 875422 - using method 3) that enabled me to identify how to remove a rogue NIC that must have been the problem. I previously tried removing the NIC with set devmgr_show_nonpresent_devices=1, and then devmgmt.msc. So I seem to now be back on track.

                      Thanks for that tip and your help.

                          So IOW at some point you changed the NIC in the server, but never told us you did that! If that is correct, it was vital missing info. If we had known that from the beginning of the thread, you would have had an answer in about 3 posts and got on track quicker.
                          Maybe I am stating the obvious, but I am doing so to point out (mainly to others) how important it is to give as much relevant info as possible from the start - help us to help you.

                          Glad you got it fixed and glad you reported back to us.
                          Thanks.
