Hello Forum,
I have exactily the same problem mentioned at the top.
Users sporadic have the error 3012 or 10 for all printers. After the next logon, no bad Messages apper.
It seems that I have the problem only on terminalservers. But I'm still working on that to find a reason. I don't want to use vbscript instead. I used kix because of the easy addprinter function. The other posts did not help me. My script is started with a gpo of a vb script that runs the kix-script with a delay of 20 seconds.
