If he's utilising an air card on the computing gadget it somewhat is sign loss. Mine drops out lots on account that I moved to a bad corner of my residing house.

Yes, try http://support.microsoft.com/kb/875357 for troubleshooting Windows Firewall.

I had a similar problem, But mine would shut down cause It needed a certain service running for the firewall which I had disabled. I don't know if yours is the samething.

do you have pre sp1 release or something cause there was vulnerability of this sort in that version, it is most probably a virus. i can't recall what it was called so i cannot help you out but go to www.symantec.com and find a diagnostic tool for the symptoms that you encounter, hopes this is useful.

download a good antivirus update it and run it in safe mode then go get your updates
