System.DirectoryServices is slow?

Question

I\'m using the code below to look up information in active directory when a user logs on to a website. Running against a local domain it\'s very quick, but running over a VP

I have never tried the scenario you are describing (connecting over VPN to Active Directory) but the line you marked is the line that causes the connection to be opened. You are not connected to the server before calling FindOne. My guess is that establishing the connection lasts 7-8 secs.
