Directory on another machine - Login credentials

Question

My application needs to access files on a remote machine that requires a username and password for accessing it.

I'm trying to find out if a directory exists (using Directory.Exists) to verify I can make the 'connection.

Is there a way to supply the username and password when working with remote directories? Currently Exists returns false.

Cheers,

Unfortunately not. You will need to wrap your code using extra code to handle impersonation of a user that does have access.

This article explains how to do it in code further down the page.

Check out this thread on MSDN Forums.

It has code sample for using impersonation, and also explains a bit about using NetUseAdd in order to gain access if the machines are on different domains or non domains.

Use the LogonUser api to login as a specific user and get a token and then use that token with WindowsIdentity.Impersonate.

Link with a sample. (do read the whole post to see it's security problems etc though).
