Client has machine that uses a proprietary program to run it and the operating system is NT4 Service Pack 6. They are using a different video card now because the old card died on them. Now, the resolution is too small and they cannot see the whole screen. It is using the Windows compatible vga driver and you can only choose 16 colors and either 480x640 or 600x800 as the resolution, which is too small. The new card (used actually) is an ATI Rage IIC 3D card which has the driver on the internet and I downloaded it from driverguide.com. When I install the new driver it says that it has been "installed successfully and I need to reboot" so it seems that all is well. When it is rebooted, it comes back up and everything is still the same. When you go to the adapter type it says it is still the "vga compatible adapter" as if the new driver was never installed. Am I missing an NT4 trick of some kind? We are logged in as the administrator which is in the administrators group on the computer. No windows domain here. I looked for a Policy editor to see if we are locked out but not sure what the nt4 policy editor is. Support for this machine or a new machine costs $4000 and that is why we are attempting this.
