Windows XP Media Center Ed. SP3, latest patches, scanned with Stopzilla, counterspy, combofix, and avg and appears to be bug-free. Nice pc, plenty of ram and processor power.
Security Center Service started. Can't bring it up in control panel or the sys tray icon. Can bring up the firewall applet but defender isn't showing. Replaced the wscsvc.dll with a good copy. The service is running and restarting it hasn't helped.
Any ideas anyone? Stubborn problem!
Thanks!
