RE: Can't access domain controller

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hello Al,

Thank you for posting to the SBS Newsgroup.

According to your description, I understand that you have a SBS 2K3 domain,
there are two Windows Server 2003 as member servers. Your issue is all
clients cannot VPN to the SBS 2K3 server. if I have misunderstood your
concern, please let me know.

Due to lack of detail information, I need your help to gather more
information for further troubleshooting:

1. What is your Network Topology? For example:

a. {SBS 2K3 Server} {ISA} {Router} {Internet} {Router} {Windows Server
2003} {Problematic Clients}. OR

b. {SBS 2K3 Server} {Windows Server 2003} {ISA} {Router} {Internet}
{Problematic Clients}. OR

c. {SBS 2K3 Server} {Windows Server 2003} {Problematic Clients} {ISA}
{Router} {Internet}

2. You mentioned "One of the 2003's is connectedthrough a VPN", I need to
know which 2003 Server you configure clients VPN to, Small Business Server
or Windows Server 2003?

3. How do you configure the VPN on the SBS side? Did you configure SBS 2K3
Server or Router as the VPN Server?

4. Please explain in detail "The VPN is Ok as I can access that side of
network".

5. Also, I have some questions regarding the sentence "the only error on
2003 server are related to that it can't find the domain controller."

a. What is the exact 2003 Server, SBS 2K3 server or Windows Server 2003?

b. On the server, run "eventvwr" (without quotation marks), check whether
there is any error, if yes, double click it, click the Copy button and
paste the full content to the Newsgroup.

c. I also need to know when the error message occurs. For example, fail to
set up VPN, VPN to domain or use RDP feature after VPN to domain.

6. When clients fail to VPN to server, do they get any error message? If
yes, please write down the error message and type the exact error message
to the Newsgroup. We need the full content of the error message for
accurate research.

For your information:

Please make sure the DNS Server IP addresses on the member Server point to
the SBS 2K3 Server.

I am appreciated your time and cooperation. If anything is unclear, please
feel free to let me know. I am looking forward to hearing from you!


Best regards,

Brandy Nee
