ok my friend send me his mmcndmgr from windows XP SP1, will it work with mine? also do i type regsvr32 mmcndmgr.dll into run command thing after i paste the dll into c:\windows\system32? will it work??

I tried my first sp2 slip stream using nlite and now it reports that dll is missing because i ignored it while installing, it was corrupted i think. I cant access my computer - hardware and god knows what else. How do i get it back?
