Filtering DFS

NTFSD
1

Anyone have any idea how to filter DFS volumes under NT4? I have tried
filtering on \Device\Dfs, \Dfs, \Device\WinDfs\Root, \Device\WinDfs, etc.
Sometimes it’s an invalid device name. Sometimes filtering it has no
effect.

Any tips would be greatly appreciated.

Thanks.

Normally you don’t need to filter DFS requests, you just need to filter the redirectors. DFS forwards all of its requests to the appropriate redirector to do the real work.

What exactly are you trying to do?

Neal,

Thanks for the reply, but I have already tried attaching to
\Device\LanmanRedirector with no luck. It works fine for regular network
volumes but not Dfs network volumes. Is there another redirector I should be
attaching to? I have already tried \Device\Dfs, \Dfs, \Device\WinDfs, etc.

I also tried monitoring for the loading of file system:
FILE_DEVICE_DFS_FILE_SYSTEM again with no results.

Again, I am only having the problem on NT4. Anything else I should try?

Many thanks.

Neil
