Recently I built up an NT 4 serv with SP4, I installed Jet admin and set up 40-45 printer shares on it and the same number of ports. All worked fine and printed test pages to all the printers. I set up HP 8000 driver for a printer that was connected, reboot and whammo......Spoolss failed to start, when I try and start Jetadmin I get exception error. The same with trying to set up port or anything else. I have removed Jet admin, been through registry and cleaned all files related to it and still when I set up Jet Admin it happens again. Has anyone had this before or know what is going on?
