Using Dial-Up and LAN connections simultaneously

Because my company does not give us access to the internet over their T1 lines, I am forced to use dial-up for internet access. I use a LAN to connect to all internal resources. The problem I am having is, I cannot use them simultaneously with the currect setup, and I was wondering if you might know a workaround. I can access everything internal over the LAN connection, but as soon as I dial-up to access internet, all my internal LAN connections are disconnected, or they use the dial-up connection instead. I am using Windows XP Pro.
Some information that may help.
Dial-Up is at default settings (with exception of the phone number, of course)
The LAN connection uses the following protocols:
Client for Microsoft Networks - all settings default
File and Printer Sharing for Mocrosoft Networks
Internet Protocol (TCP/IP) - Using a static(fixed) 10.2.x.x
Gateway 10.2.x.x
DNS Servers 166.70.x.x
WINS 166.70.x.x
Any help you can offer would be appreciated. Thank you,
Gush

Where are they, on your local network or on the Internet? Larry

The DNS servers are for the local connection. I don't have any DNS servers manually assigned for Dial-up. It uses the default settings to obtain automatically. Although I could configure them manually...hmmm.

Then that's not the problem. DNS server assignment would normally be done automatically on most Internet dial-ups. I don't have an XP computer set-up at present. I did look at my 2000 server on this, which is somewhat similar, but could not find what I was looking for. I am fairly sure from seeing this problem with Win 9x, that somewhere there is a configuration setting that is causing the problem and it probably has to do with security or the connection settings in the Internet connection properties. It might be the XP firewall (http://www.microsoft.com/windowsxp/pro/using/howto/networking/icf.asp). Larry
