Unable to Remote Desktop into my office PC over SBS 2003 VPN

Hi,

I'm able to Remote Desktop into our SBS 2003 server, and from there to any other PC or server in our LAN.
However, I'm unable to Remote Desktop into my office PC over SBS 2003 VPN from my home PC. I'm unable to RD into any other computer as well.

Any ideas?

Thanks!

It was a DNS problem. I edited the hosts file and that solved the problem.

check if the firewall is turned on our office pc? if so turn it off.
Also ensure the remote desktop is enabled

The firewall on my home PC is OFF.
Remote Desktop is enabled on my office PC, else, I wouldn't be able to RD into it from our SBS.

ok..got it..do this,

create a backup of the MSLicensing registry key and its subkeys on the client, and then remove the original key and subkeys by doing the following:

On the client, navigate to the following registry subkey: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSLicensing.

Click MSLicensing.

On the Registry menu, click Export Registry File.

In the File name box, type mslicensingbackup, and then click Save.

If you need to restore this registry key in the future, double-click mslicensingbackup.reg.

On the Edit menu, click Delete, and then click Yes to confirm the deletion of the MSLicensing registry subkey.

Close Registry Editor, and then restart the computer.

When the client is restarted, the missing registry key is rebuilt.

Great, I'll try that, but who do you call the client, my home PC, my office PC or the SBS?

Sorry, that didn't work. The MSLicensing key was not recreated. I can still RD into my SBS.
FYI I can ping my office PC from my home PC while in the VPN. RD doesn't work with either name or ip address.

have you forwarded the proper ports on your router that is connected on the lan? For all SBS functions to work properly, you must forward the following ports to the SBS server:

3389 - Remote Desktop Protocol
444 - SharePoint Site/Remote Web
1723 - VPN
25 - Simple Mail Transfer Protocol
80 - Home Page Web
443 - SSL
4125 - Remote Web Workplace
21 - File transfer protocol
110 - POP3

If you don't intend to use the specific functions, then obviously don't forward them for security reasons. Especially FTP. Obviously, RDP is what we're most interested in right now.

abatemc, if I'm able to RDP to the SBS server, I imagine all those ports have been forwarded. But before that, doesnt the VPN obviates the need for all that?
