I have Windows XP installed on my computer which has some issues due to which "DHCP Client" service often fails, earlier I could rectify this just by starting the service, however recently I switched to broadband connection (from earlier "WiMax" one), and now even after I restart the service (after it stops), connection doesn't work and the only resort for me is to restart my computer. I suspect it might be due to some other service, but I am not able to find it.

Any help will be most appreciated

run command prompt with admin rights and run "sfc /scannow" to ensure that system files are okay. – tumchaaditya May 28 '12 at 6:27
@tumchaaditya Thanks I will try, just a question though how do I run command prompt on XP with admin rights I thought it was just for Win 7 – Gaurav May 28 '12 at 6:31
If you are using an account with admin privileges(which is usually the case with home PCs), run it directly from "Run". – tumchaaditya May 28 '12 at 6:48
@tumchaaditya OK I ran the command, I am getting a prompt "Files that are required for Windows to run properly must be copied to the DLL Cache. Insert your Win XP SP2 CD now" – Gaurav May 28 '12 at 7:03
well then do so.. :) sfc(system file checker) utility checks all system files for any discrepancy and replaces any faulty file. For that, it is gonna require original files. btw, which broadband do you use? is it MTNL/BSNL? – tumchaaditya May 28 '12 at 7:39
