invisible firewall

[Jonl521]

My internet has been blocked from getting to my programs/browser, even when I've turn my firewall( and the windows one) off.

I still have a strong connection but firefox is blank, and it wont load ( or attempt to) any site. I've run many malware/anti virus, and i'm pretty sure that's not it.

The last thing I remember using before this happened is SDfix, so i'm pretty sure it changed some settings or something.


Name of your ISP: Comcast
Make and exact model of the broadband modem: RCA DCM315R
Make and exact model of the router (if a separate unit): lnksys wrt54g v8.2
Make and model of your computer: XPS DXPO51
Version and patch level of Windows on all affected machines, i.e. XP-Home (or XP-Pro), SP1-SP2, Vista, etc: xp Service pack 3
The Internet Browser: Mozilla Firefox 3.0.8
The other computers on the network work fine by the way.

thanks for reading, if there is any more information you need, just ask.

To open the command prompt: Start > Run > CMD
Then enter the above commands. I think what you did is type them into the run dialog box which will run the command and then instantly close.

I solved the problem thanks to Johnwill

for people who may have the same problem in the future...
Start, Run, CMD to open a command prompt:

In the command prompt window that opens, type type the following commands:

Note: Type only the text in bold for the following commands.

Reset TCP/IP stack to installation defaults, type: netsh int ip reset reset.log

Reset WINSOCK entries to installation defaults, type: netsh winsock reset catalog

Reboot the machine.
