On a W2K machine I had a virus MSBLAST.EXE. I followed instructions on the Symantec site and removed it. Installed Microsoft Security Patch too. I reinstalled W2K.
When I try to reinstall the printer which was installed, I get a message that it cannot install a printer because a subsystem is not available.
I often get messages from SPOOLSV.EXE that it has generated errors and will be closed by windows.You need to restart the programm.
