Guest JohnB Posted June 15, 2008 Posted June 15, 2008 I am fixing a computer for a friend. The PC is running XP Pro, SP2. It was infected with a bunch of viruses. After a lot of research, the fix turned out to be something called SDfix.exe. The computer uses McAfee and all it was doing was deleting viruses by the thousands.... over and over. Then I ran the SDfix and all that stopped. There were no more problems, except one; the computer will not get a DHCP address from the router. I can put in a static IP address and it works fine. Put it back to DHCP and it doesn't get an address. I tried resetting the IP static using netsh. That didn't work. Has anyone seen this before? This is not a router issue. Any ideas would be appreciated. Thanks.

Many forms of adware/spyware insert a Layered Service Provider (LSP) into the Windows Sockets (WINSOCK) and if you remove the malware but not the LSP you break the IP stack. Set the PC's IP statically. If it does not access the Internet then you know the above is true. The following tool is effective in fixing WINSOCK.

Guest JohnB Posted June 15, 2008 Posted June 15, 2008 Re: Won't pickup DHCP address Yeah, that is exactly the case; if I set a static IP address, along with IP addresses for DNS, everything is fine. I'll try the WINSOCK fix now. > I'll bet the PC was infected with non-viral malware and not "viruses". > > Many forms of adware/spyware insert a Layered Service Provider (LSP) into > the Windows > Sockets (WINSOCK) and if you remove the malware but not the LSP you break > the IP stack. > > Set the PC's IP statically.

Guest JohnB Posted June 15, 2008 Posted June 15, 2008 Re: Won't pickup DHCP address I just tried that tool, and that reported that there aren't any problems with the WINSOCK. I found another page that said to run MSinfo32, and you could check the status of WINSOCK with that, it it's fine there too. But I agree, that the malware changed something that has affected DHCP on this PC. "David H.

Guest JohnB Posted June 15, 2008 Posted June 15, 2008 Re: Won't pickup DHCP address I get nothing in the application log and, in the Security log I get one event: 1007 And any Googling on that only points to problems with the DHCP server.

Guest JohnB Posted June 15, 2008 Posted June 15, 2008 Re: Won't pickup DHCP address I downloaded it and took a look at your batch file. All it does is reset the stack using Netsh, which as I said, I've already done. I noticed you did a reboot after the reset, and I hadn't rebooted after the reset I did, so I ran your batch file but... same result, no connectivity. Just for grins I downloaded and installed SP3, but that didn't help either.

Sorry. If you set the IP stack statically and you can get on the Internet then then you didn't have to use LSPFix as the IP stack isn't broken. I also see that it was suggested to check the state of the DHCP Client Service and it was started OK. I also see the suggestion to remove the TCP/IP protcol and reboot and that you could not. Here I suggest moving the NIC to a different PCI slot. I relaize that if the NIC is embedded on the motherboard you can't do this. If this is the case I suggest installing a NIC on the PCI bus and see if you get get a TCP/IP address lease. -- Dave http://www.claymania.com/removal-trojan-adware.html Multi-AV - http://www.pctipp.ch/downloads/dl/35905.asp
Guest JohnB Posted June 15, 2008 Posted June 15, 2008 Re: Won't pickup DHCP address Unfortunately, I don't have a spare NIC.

Guest R.

They can be found at: HKLM\System\CurrentControlSet\Control\Network *Usually indented 2 levels below the first GUID, identified with the Connection Sub-Key. Remove the GUID directly above the Connection key to remove the LAC.

Currently you work fine when set with a static IP, but don't work when trying to obtain a dynamic IP? Connected directly to your ISP, or are you getting the IP from your router? When you run IPCONFIG /ALL what is your MAC address?

Silly question, but the DHCP server is enabled on the router, right? :)
Guest JohnB Posted June 16, 2008 Posted June 16, 2008 Re: Won't pickup DHCP address DHCP works fine on the router - I have 2, both work fine, with other PC's.

At this point, I'd install a freeware network analyzer program like Wireshark on your problem machine: <http://www.wireshark.org/download.html> After installing and running, initiate a network repair and see where in the DHCP sequence it is failing.
