Unable to login into SBS 2003 Domain server
LockedProblems:
1. Vista workstations are configured for DHCP but cannot get an IP address from the SBS Server/DC. They get 169.254 ip addresses
2. Vista & XP Workstations cannot access their email via Outlook
3. Workstations cannot remote desktop to SBS server/Domain controller
4. SBS/DC Server (ABCSBS01)We think the problem is with the DNS setup, however nothing has changed in DNS Setup.
Environment:
? Vista SP1 workstations with Office/Outlook 2007
? XP SP2 & SP3 workstations with Office/Outlook 2003
? Win 2003 SBS Server SP2 with Exchange, is Domain Controller & DNS Server DHCP Server (SBS/DC) (192.168.0.2 & 192.168.0.8). No Windows firewall (ABCSBS01)
? Win 2003 File Server, also a Domain Controller (192.168.0.3). No Windows Firewall. (ABCFS01)
? Motorola Surfboard Cable Modem ? DHCP is disabled (192.168.100.1)
? Smoothwall firewall (192.168.0.1)Recent maintenance tasks on server
The only maintenance task done on the SBS/DC was to swap the EXCHSRVR disk that contains the MDBData files. No program folder locations were changed. After stopping the Exchange services, these files were relocated to a new disk and the disk was allocated the same drive letter as the former disk. All the Exchange services start without error and we can access the Exchange mail box via OWA on the SBS/DC.Connectivity tests
Workstations
? Vista workstations attempt to log on to the SBS and get a 169.254.* IP address as the IP address is not handed out.
? On Vista workstations, Connection-specific DNS suffix is blank in IPconfig.
? When doing Network Diagnostics, we get Windows cannot find ?ABCSBS01? Click for more information about DNS.
? When doing ipconfig /displayDNS, Name does not exist appears in relation to all the DNS servers that are described in our DNS setup (viz ABCSBS01, ABCFS01, _kerberos._tcp.dc._msdcs.ABC.local, _ldap._tcp.dc._msdcs.ABC.local. Many external web sites are listed here also.
? Have done Ipconfig /flushDNS, Ipconfig /degisterDNS
? XP workstations can get a valid 192.168 ip address but cannot access Exchange via Outlook. Connection-specific DNS suffix is not blank in IPconfig
? If we configure a Vista Workstations with Fixed IP address, it can access the domain resources (files & folders on the file server) but cannot access email on the exchange server. Either a local PST is opened or a workstation issues the error Microsoft Exchange server is unavailable. Retry/Work offline/Cancel.
? Can remote desktop to the ABCFS01 File server but not to the SBS/DC ABCSBS01
? From any workstation, when we attempt to ping the SBS/DC ? via IP address or workstation name, we get time-outs
? When doing NSLookupwe get a DNS request timeout with Server UnKnown however the correct Ip address of the DNS server is returned.
? Only some workstations are displayed in Network leaf of Explorer.SBS/DC (ABCSBS01) ? Connectivity
? When doing IPConfig, we get 2 IP addresses returned for the same NIC (192.168.0.2 & 192.168.0.8). This has been the case for a very long time without problem. The old IP address that probably was used by an old NIC is displaying along with the current IP address.
? When pinging itself via w/station name ? viz ABCsbs01, we get the valid ip address returned. When we ping that same IP address, we get the workstation name returned
? When we ping the additional IP address, we also get successful
? Can access the File server file via Remote Desktop and can access files & folders on the file server
? Can access the internetDHCP ? services are started
Net Logon services are startedI don’t believe we have any group policies that would be preventing us from logging in.
DNS Setup
Round robin is not enabled. Dynamic updates is enabled ? secure only 7 days.
The server name ABCSBS01.local appears with every occurrence of the valid IIP address (192.168.0.2). The old IP address (192.168.0.8) is also listed with the server name in the DNS setup along with the current IP addressof the server in DomainDNSZones & ForestDNSZones in the DNS setup
We have done, Ipconfig /FlushDNS, Ipconfig /RegisterDNS, DCDiag /FIX, Net stop netlogin, Net Start netLogin.
When we run DCDiag again, we still get the error GUID
._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.
Where do we enter the name of the server to overcome the UnKnown error in the DNS name?
We have looked through the event logs and haven?t 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 boxes via Outlook?
