Hi,

My machine is running XP Pro SP2 with NO third party anti-virus protection
program and not on any private network.

Last couple of days I sorted out the Firewall option unintentionally
disabled, then I checked the properties it prompted up "No ICS services blar
blar blar" then I clicked "OK" and showed the Firewall turned off and all
option buttons turned grey/dimmed. Nothing I can do.

I've checked any hijack/ worm/ virus but nothing related to the captioned.
I've also looked up previous posts regarding similar firewall problem and
resolutions but no success at all.

One more issue come up to my machine that has not been mentioned in previous
post. The internet access for sure will suspended in 3 to 5 minutes after
boot up and before the suspension a DOS-based programme flashed up and
terminated (and the connecting speed is slowwwww).
The DOS exe file named USBUP???.exe will store in the installed windows root
directory. When I open the exe, it was written something "Bandwidth excess".

Then I thought would that be my ISP problem, I plugged in the LAN to my
another computer, everything works fine (no connectivity problem, no firework
auto turn off problem).

People, is there anyway I can resolve the problem without tedious
re-installation!!!!

Thanks in advance.
