XP - DHCP not assigning an address

November 28, 2010 at 07:27:02
Specs: Windows XP Pro
My house laptop with XP Pro showed the dreaded "Limited or no connectivity" for both cable and wireless, and the cause is apparently the lack of a DHCP address designation. My two other laptops are connected [wireless] to the same router and are fine. A few reboots of the laptop and the router and reinstalling of XP did not help. The router shows the DHCP addresses of the other laptops, but not the one of the house laptop. Ipconfig shows a 169.254 address.
May be related issues: I cannot start the "Help and Support", although services.msc shows clearly this service is up and running. Another weird thing was the sudden automatic re-install of Adobe Acrobat 8.2, although this was installed before and I have Adobe Acrobat Pro.

Other tidbits of information:
- pinging 127.0.0.1 brings a reply;
- ran Malware, TFC, Spybot S&D, SuperAntiSpyware, and RootRepeal to no avail;
- checked all services against www.blackviper.com list.

Combofix seems to have it fixed!

It would be nice to know how combofix.exe fixed it and what it fixed ... :-) But at the end, all that matters is that I got access again!
