Corrupt WMI and cannot copy files from Windows CD

Dear mates!

I have got Corrupt WMI on my Windows XP with Sp2. I have tried when i am
trying to rebuild it using following command;

rundll32.exe setupapi,InstallHinfSection WBEM 132 %windir%\inf\wbemoc.inf
(reference: http://windowsxp.mvps.org/repairwmi.htm)

It is asking me to provide path to 'Windows XP Professional Service Pack 2
CD'. I have tried inserting that CD and browse it to i386.. but it keeps
asking me this.. I even tried other cd which is with winxp sp1 (I installed
Windows originally from it) .. I even tried to create slipstreamed CD with
Sp2.. But It just Doesn't accept the Location....

I wonder whats the issue here?? Why its not accepting the file which i am
giving it the Right path???

I Don't want to do INLINE installation to fix WMI issue as given on
Microsoft site.

Can any one help with it??

Regards,

Asad.
