Replacing lcd screen on a hp dv6 laptop

I have replaced several lcd screens on the laptops in the past replacing screen on a hp dv6 laptop however was not that straight forward.I had to dismantle the entire laptop to get to the broken lcd.Here is how you get to the lcd.

DirectorySearcher PropertiesToLoad Add is not working

If you have played with or is using System.DirectoryServices.ActiveDirectory, you might jump into the consclusio that "DirectorySearcher PropertiesToLoad.Add " is not working/useless/will be ignored.But that might not be the case.

We have also users under like a2\user1,a2\user2...; also we have rda2\user3 rda2\user4....;
I dont have lot of knowledge about "AD" structure or the terminology.I dont know how the rda2\user3,user4 ended up under

My user is rda2\user3 and if look at the user domain using the "set" command I get, my user dns domain is rda2.

The problem is in my windows app I am trying to show the list of users under every domain
It shows somethings like this in the treeview
But users rda2\user3 and rda2\user4 is missing from the list.

I use the following code to get the list of users.Also I use the windows …
