Hi there,

I was wondering if its possible to identify the server that the clients are connected. I got 3 file servers in differents locations using the DFS Namepace to get high availability of the files, but I would like to know, where the clients on site A are getting the files if the File Server of site A fails.

You could probably sniff the packets on the network and get an MAC address.

But is there a command line or some tool to get this information? Didnt want to use a sniffer to get this.

I'm not aware of a tool to do what you want.  The point of DFS is to be transparent, so...

Ok... Do you know which port does DFS use?

Hmm. When a client wants to access something in a DFS share, the client obtains a referral to a partner in the share from Active Directory.  The client then accesses the share directly.  Since what you want is to know which server the client is accessing, your best bet is to sniff the traffic at the client.

Between DFS servers, I'd expect normal RPC traffic for both coordination and sychronization.  More information here:

You can look at the Shred Folders on each server to see which clients are conencted to the shares. (Computer Management, Shared Folders, Open files). From the client, you can right click on a folder, go to Properties, DFS tab, and it will show you the available DFS targets and which one is the active connection.
