DHCP Client cannot get IP from DHCP server

Guest

My laptop uses XP Home.

I deleted some files on disk and in registry related to some SpyWare/AdWare (SahAgent and Wupdater).
After that my networking function desn't work. Now I have reinstalled XP (upgrade) and changed the registry according to Q329441.

It still doesn't work. Please help me.

[Information on using ping]
My laptop is DHCP enabled, which could get an IP from DHCP server. But now it doesn't work.

It cannot get an IP similar to before. It only has an autoconfigured IP address, which doesn't have a default gateway.

ping works fine for 127.0.0.1 and computer IP.

If I disable DHCP and use previous IP, ping doesn't work for the default gateway.

[Information on using net view]
C:\>net view /network:nw \\My_PC_Name
System error 1204 has occurred.

The specified network provider name is invalid.

Thank you very much!

Merry Christmas and Happy New Year!
