NW6.5 sp2 with NDPS several locations 2 different nds-trees.

We have a problem with our HP4200 postscript drivers when they are installed
automatic during login. (The problem is gone if the users install the
printer by pointing to the NDPS printer and let it install this way)

The problem: when trying to access properties the is an errorcode i
"Function address 0x77c48196 caused a protection fault. (exception code
some or all property page(s) may not be displayed."

When pressing "OK"
Then it says
Printer Properties
The "HP LaserLet 4200 PS" printer driver is not installed on this computer.
SOme printer properties will not be accessible unless you install the
printer driver.
Do you want to install the driver now?
