Change DSN Server Entries by User?


Recommended Posts

I'm looking for a way to set the DNS server on a Win7 workstation by user. So I would like the DSN server for userA to point to 1.1.1.1, and the DNS server for userB to point to 2.2.2.2. I would like it to automatically switch to the corresponding DNS server everytime the Windows "switch user" functionality is invoked. I would like this to happen as seamlessly as possible in the background. Any help/suggestions?

Hi, KeithAbbot. You can set this in the registry under HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParametersInterfaces. Find the key for your network adapters, and the value "NameServer". Check out RegRead and RegWrite in the Helpfile for ways to input this info. Try your hand at writing a script, and feel free to post what you have here if you run into any issues. ;)

Also look at the netsh commands in Windows too.

I would think putting it in the user's startup folder would do the trick; it should run as soon as they log in.

Putting it in the startup folder would only execute upon initial log in for a given user. When a switch user event occurs (i.e. switching from UserA to UserB, when both users have previously established sessions), the entries in the startup folder are not re-executed. I need to be able to trigger an event any time a login or switch user happens.

If you're allowing Fast User Switching, you're going to run into problem, because the script process from User 1 will still be running. Is this a hard and fast requirement for your environment, or can you disable Fast User Switching to make users log off?
