Hi all

I have one machine (A) which is not on a domain. There is an local user
account on A (userA) that has access to a certain folder. I have another
machine (B). An application on B initialises a FileSystemWatcher to watch
the previously mentioned folder on A.

My question is: how do I ensure that the FileSystemWatcher is operating
under the local account userA on machine A? I've explored LogonUser(...),
but this appears to only work either on the local machine, or if the account
to be impersonated is on a domain.

Any pointers gratefully received.

Cheers!
 
Hi Chris,

From your description, you have two machines in a non-domain local
intranet. And you will use FileSystemWatcher to monitor folders from one
machine to another one and want to ensure the watcher will act like a local
user account(permission) on the remote machine, correct?

As for this scenario, I think you can use the "duplicated account" feature
of windows NTLM authentication. Suppose you haven't domain environment, you
can still make two windows machines share local accounts when the program
on each machine visit the another(remotely) through the following means:

** create two duplicated accounts (with identical username/password) on the
two machines(A and B)

** Then, you can run program on A with the MACHINEA\DuplicatedAccount and
when it access remote resource on B(such as fileshare), it will be
authenticated and recognized as MACHINEB\DuplicatedAccount.

Here are two former threads where I've also mentioned this:

In addition, if you have interests ,you can also look up the "programming
windows security" book authored by Keith Brown for detailed information.

Hope this helps.
