I've noticed that a few people have posted concerning this topic, so I've tried to read up on as many possible solutions before posting. I'm recently recovering from a mild virus infection on my computer, and noticed that after I had run Avast! and Malwarebytes to remove the virus, my computer lost its internet functionality. Upon running ipconfig in command prompt, I noticed that the computer was not being assigned an IP address, which lead me to believe there could be an issue with DHCP.
When running services.msc, I notice that both DHCP client and TCP/IP netbios are not running, and when I try to run them, I get an error 1075, that the files are "either non-existent or marked for deletion". I noticed that someone else had posted a very similar problem, but a few of the more advanced fixes seemed specifically tailored for their issue.
Below are the fixes I've attempted thus far -
1. Checked the registry for DHCP’s dependencies (3 are listed, Afd, Tcpip, and NetBT).
2. Reset TCP/IP stack to installation defaults by typing “netsh int ip reset reset.log” into command prompt.
3. Reset WINSOCK entries to installation defaults by typing “netsh winsock reset catalog” into command prompt.
4. Ran “sfc /scannow” with an XP SP3 CD.
I'm currently running Windows XP Media Center, Service Pack 3 on a Dell Inspiron E1505 laptop I had purchased in mid-2006.
