JSI Tip 8852. SFC.EXE does NOT allow a network share that contains the CD image?

When you run SFC.EXE /SCANNOW (System File Checker) in Windows XP SP2, or Windows Server 2003 SP1, you are prompted for the CD, but SFC.EXE will not accept a network share that contains the CD.

The behavior will occur if you deploy the service pack from a network share, and the ServicePackSourcePath has been modified to point to a network share that contains the extracted files.

To workaround this behavior, run SP.BAT on the client computer.

SP.BAT contains:

@echo Off
set key="HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup"
REG ADD %key% /V ServicePackSourcePath /T REG_SZ /D "%SystemRoot%\ServicePackFiles" /F
