Deleted dll files creating problem how recover them new one

[zillah]

I followed the instruction in this URL because I expierneced the error message.
http://support.microsoft.com/?kbid=261302

The file that I deleted from C:\WINDOWS\System32 were :

Wsnmp32.dll, Ntprint.dll, Tcpmib.dll, Mgmtapi.dll, or Snmpapi.dll.

Now when I click "Add a printer" I received this error :

"Operation Could not completed", Which I had no such problem before deleting the files above.

How can I replace the deleted files with new one ? (Can I downlod them ?)

Get your Windows CD on the ready and run the System File Checker (SFC).
