[Solution]: NetSupport School 10 crashes Vista

I am posting here the problem and solution in case if anybody else has the same issue.

Symptoms:

Our institution utilizes Netsupport School 10 to control students workstation and stream presentations during the class. I was creating a new image with Vista Business (we are moving to it from Windows XP) yesterday and noticed that every time when i try to connect to a client also ver.10 Vista would crash with a blue screen or it was re-drawing screen very slow and then crashing. The crash usually took about 1-2 seconds and it was restarting the workstation right away by itself.

Resolution

After some googling I found out that video drivers had to be reset before you will be able to connect to the NSS client with out causing Vista to crash.

1) Install Netsupport Manager's “Client” option; make sure that "Reset Video Drivers" option is also selected. Once it's installed run the "Reset video driver" and allow it to reconfigure the video drivers.
Restart the workstation when it asks you to do so.
Uninstall the Netsupport Manager.

2) Now you can install the Netsupport School's “Student option”. Try connecting to the client end from Tutor's workstation again; you should not have any problems with screen re-drawing or Vista crashing now.

Once the drivers were I sysprep-ed the image and restore it successfully later on on a similar hardware. No more problems with NSS 10 client crashing Vista.

Vista KMS client problems.

Was getting the following error on one of the locations.

0x8007232B
DNS name does not exist.

The DNS setting was setup correctly as was the IP and Gateway. I did not have a DHCP setup at the location. The problem was in the workstation's DNS suffix. Workstation located the KMS host and activated by itself once i have added the correct "Primary DNS suffix" in the computer properties.

If you have a DHCP on the site then you don't have to walk up to each workstation to change the DNS suffix in order to activate it. Just make sure that option 15 [DNS suffix list] is added to the DHCP options and DNS servers listed correctly. Clear the DHCP table, run the following on the client;

ipconfig /release
ipconfig /renew

and the workstation will activate by itself.

If you are using the KMS host on a different site with different domain then add the KMS location to the client manually as following:

cscript c:\windows\system32\slmgr.vbs -skms Kms_FQDN

Make sure that you runing the above command in command prompt with elevated privileges.
