1)The Vista Machine no longer connected to the internet. Though it could ping the server.
2) The server on a different NIC could ping the router but would not bring up the config page for it and would not connect to the internet.
After a while I reconnected the Vista machine directly to the router and then it connected to the internet just fine. Though the server 2003 machine can not. I have not added any new software to it except Bit defender as it was the only tool I could find to run on 2003 for free. Though I can't see anything obvious in its controls which could be blocking connections. Any ideas?
