Browser connection timing out; possibly DNS related issue

im using my spare ethernet card now but im still getting the DNS error. at this point i dont know what else to do, theres a small chance it might be the cable modem so ill see about getting a new one from my ISP.

Click on Start, Run and type in cmd.
At the command prompt, type in:

ipconfig /flushdns

...and press Enter.

Type exit and see if it works now.

Well i finally "fixed" it. not exactly a fix but more of a trick. i installed Microsoft's .NET framework 1.1 which creates a login prompt at the login screen instead of automatically logging you in. here i just wait for about 10 minutes and after i log in there are no connection errors. even the programs that never used to work now can access the internet without a problem like BF2 and Steam.

so thanks to all who replied and tried to help me fix this problem.
