I am running XP Pro with SP3 on a system with a 3.2 Mhz processor and 1 G of\nmemory. I have two 149 G drives, each with about 63G of free space. When I\nstarted the system this morning, Windows displayed a message headed "Data\nExecution Prevention" and reading "To help protect your computer, Windows has\nclosed this program. Name: Spooler Subsystem App Publisher: Microsoft\nCorporation".\n\nAll of my printers - 2 local and 2 networked - have disappeared, and when I\ntry to reinstall them Windows displays the message "Operation could not be\ncompleted. The print spooler service is not running."\n\nEverything seemed to be working normally yesterday.\n\nI ran a full virus scan after getting this error - it says the system is\nclean.\n\nThe formerly installed printers are -\n1) HP2200 on LPT1 - this was set to allow shared access since several users\nneed to print to it\n2) Xerox Phaser 6250 on USB\n3) HP4000 on an internal IP address\n4) HP1312 on an internal IP address\nPrinters 1, 2, and 3 have been installed on this system for several years. I\ninstalled the HP1312 on Tuesday Jan 13 to troubleshoot why its primary user\nwas getting error messages from it. I don't think I'll reinstall it...\n\nThere are 35 other systems in use in this building, and since no one has\nphoned me for support I believe my system is the only one showing this\nproblem.\n\nHow can I get my printing to work again?
