Invalidate File System cache in Windows server 2003

NTFSD
1

Hello,
I have a situation where I need to make sure that the file system cache
is cleaned (invalidated).
Here is my scenario:

  1. do a flush command for a volume
  2. un mount the volume
  3. do some changes to the volume data on another computer
  4. Mount the volume in the system again

What I get now is the old data on the volume, the cache still holds the
old data, and was not invalidated…

Any suggestions? Would a Lock to the volume before un mount will help
here?

Thanks,
Yohai Merzel
