ISDN router not working with MS SBS

[Keith Macdonald]

We have a Zycel Prestige 100 ISDN router that works fine when the only PC's booted are the ones running NT4.0 workstation. When we boot a PC running MS Small Business Server, access to the router seems to get blocked. As I understand it the SBS box is a domain controller and a proxy server. What is the most likely cause for the NT workstations being blocked from internet access?

Your most likely cause for not being able to access the ISDN router is because you are running proxy server. If you do not need or use proxy server, remove it from the server and you should be fine. However, if your ISDN router offers no firewall seci=urity, I would keep the proxy server behind the router and configure proxy server with your internal address range in the LAT. One other thing to check is to make sure your router's IP is not in the LAT on the proxy. This will cause your access to be blocked.
