Vista Forums - View Single Post

I've searched through here a bit and it seems like others have had this problem, hoping I can find a solution.

Recently bought a new machine after my old computer's motherboard died. HP desktop running Vista Home Premium, 3GB ram, 3 ghz processor. Networking was working fine at home, and I was actually enjoying the whole experience more than I expected coming into Vista. Yesterday I took the computer to a LAN party, and as soon as I got there the problems began.

On startup at the LAN party, I noticed that the network connection icon had the red x, and said network status unknown. After about an hour of searching around, I found that the issue stemmed from the DHCP Service's inability to start properly. (Also, ironically, the system event viewer service is unable to start as well, which restricts me from viewing the error log, as far as I can tell.)

Some system info I've seen requested before related to this problem:

I'm at my wit's end here... I've even gone so far as to attempt a system restore from many different restore points, they continuously encounter unexpected errors and do not work. Any help is appreciated.
