RE: VPN via extended firewall toSBS2003

Hi Thuur,

Thank you for posting in the SBS newsgroup.

Is the remote computer able to ping the SBS Server's FQDN? (servername.domain.local) Is the remote
computer able to ping other corporate computers' IP/NetBIOS/FQDN?

First of all, please try ping the SBS machine with -a switch. To do so:

1. Open CMD prompt.
2. Key in the following command and press Enter.
Ping -a xxx.xxx.xxx.xxx (where xxx.xxx.xxx.xxx is the IP address of the SBS machine.)
3. Let me know the outcome.

Then, please run NBTstat /RR command on the client computer. (Note: the /RR are capital letters.)

Please make sure that the corporate LAN and the remote XP computer's local network are not sharing the
same subnet. (For example, if your corporate LAN is on 192.168.0.x, the remote client computer's network
should be on 192.168.1.x.)

Please let me know the following commands' output from both the server and the client:

1. IPConfig /all
2. Route Print

For a quick solution:

1. On the problematic computer, go to c:\windows\system32\drivers\etc\ directory.
2. Rename lmhosts.sam to lmhosts.
3. Open lmhosts with Notepad.
4. Add the following content at the end of the file:
xxx.xxx.xxx.xxx SBSNETBIOSNAME
(where xxx.xxx.xxx.xxx is the IP address of the SBS machine and the SBSNETBIOSNAME is the SBS
machine's NetBIOS name.)
5. Save the file and reboot the computer.

I hope the above info helps.

Any update, let's get in touch.
