Hi I have sbs 2003 running behind a dlink router that has nat and a firewall.  The windows firewall won't start -- It says another program or service is running that might use the nat. component ipnat.sys  The server has two nics -- one for the lan and one that plugs into the router for the wan.

thanks

The Windows Firewall isn't supposed to start.  That service should be disabled.  RRAS is handling your firewall and NAT on the SBS.

Hopefully you've got the NICs configured correctly as well.  (an example is at http://sbsurl.com/twonics)
