I lost my password, what can I do now

Plug in an ethernet cord and type in these numbers in the web address field and enter admin for the username and Motorola for the password and log in. Otherwise, find the reset button on the router. Press and hold for about 30 seconds to perform factory reset. Then you'll need to reset everything.

I am unable to access my company's vpn server.

You may have some needed firewall ports blocked on your router. Turn off the firewall temporally and see if your able to connect. Your company IT folks should be able to tell you what ports they need open.

I don't see Vista listed in the SBG Manual, but they do list several windowS OS versions. Looking at Windows 2000 for an example, you basically need to go into the control panel and make sure TCP/IP is configured correctly. If Internet Protocol (TCP/IP) is in the list of components, TCP/IP is installed. You can skip to step 10. If Internet Protocol (TCP/IP) is not in the list, click Install. The Select Network Component Type window is displayed: In both cases, the box next to Internet Protocol (TCP/IP) needs to be selected. If you need the steps in selecting the network component type let me know and I'll try to post those steps also.
