Network setup:

Main site:
SBS Server 2003 (is dhcp server), one nic, ip range 192.168.19.X, 30 clients

Remote site:
2 desktop pcs, ip range 192.168.20.x, firewall/router = dhcp server

Both sites are connected with a vpn tunnel between 2 SGS320 appliances.

At the remote sites clients can connect to exchange and network shares. They get their ip adresses from the SGS320, working ok.

I have troubles printing from main site to the remote site, think dns is not working properly. Can someone advice me how to setup this situation properly and secure?

At remote site i want to use the router/firewall as dhcp server.

Are you using ISA to connect the two sites or another firewall?

No, using a hardware vpn tunnel between the 2 appliances. The SGS320 appliance also function ad firewall.

I googled around a bit - in many articles people are setting op a second DC in remote office. This is not an option for me, I just want these two clients working perfect in the domain without installing another DC.

Is this possible?

In your VPN client look for the DNS settings and then hardcode in the DNS from your local machine...

Is windows firewall enabled on your client pc's?  If so you might have to change your sbs server group policy to make the windows firewall allow access to both your local subnet and the remote one.

Thanks for the advices.

The hardcoding of dns server is the only option, but I do want the clients to be configured through dhcp (sgs320 on remote site is now dhcp). Since i see no options to let this router hand out predefined dns server i think this is an impossible situation here.

Firewalls are off as on all the client pcs.

For now i configured the clients with dynamic ip adresses and static dns (pointing to sbsserver). All works well.

Too bad i cant do everything with dhcp, read something about dhcp relaying but thats not possible with SGS230.

Computerguy 107 took me back in to the right direction, points are his.

thx everybody for the help
