I have a really odd problem with a sbs 2003 server. It is basically losing its default gateway setting and therefore losing its internet connection. This happens roughly every 5 minutes where the connection will stop, if I then do an ipconfig the default gateway has disappeared, then is magically reappears and starts working again
After much messing around it looks as though there is a problem in the routing table but as I'm not that clued up on it I'm not sure how to get around this problem.
If I do a route print command when it goes pair shaped I get this odd entry
Notice the ffffffff entry under the interface with no gateway ip. I then do a route delete command to bin that entry and guess what happens???
The correct entry for the gateway and interface automatically gets created and the internet works fine until it happens again.
Any ideas as I'm stumped. It has all the lastest 2003 server, sbs 2003 and exchange service packs installed. When it was originally installed I used the internet and email connection wizard as it was using an ISDN terminal adapter to connect to the net but now its using an adsl router, and is reconfigured to use that. Could some setting be refreshing in the background to cause this issue?
Thanks for any help.
