I'm a computer tech and have been completely stumped by this problem I'm having on a clients machine.
I can browse the web just fine on it, but I cannot access anything else, including secure web sites. For example, when attempting to update spybot, it immediately gives me "Connection Refused". When using a utility to see what is happening, no connection is even attempted.
I have ran every adware/spyware/virus removal tool known to man on it (updated manually). The machine is very clean. I have also used 4 different rootkit scanners on it to no avail (been finding rootkits on machines lately).
I have ran the winxp winsock fix utility. I have done a windows xp repair install. I have replaced the NIC.
I have checked the HOSTS file, I have removed and reinstalled everything that has anything to do with the network.
I have turned off XP firewall and temp disabled all programs from starting up. There is no other firewall installed on the machine.
You can eliminate any outside cause (LAN/router, etc) as this is happening at the clients site and here on our work LAN (where all the other machines can access everything just fine).
I have done quite a bit more as well, but this post is getting rather large enough. I have searched all over the net for others having this problem and have tried any solutions suggested (most have no responses).
So at this point, I'm stumped at what to try next. Any suggestions?
Thanks a lot for your time!
