I have encountered some system instability with MS Outlook but seem to have fixed it with "Detect and Repair". However I cannot use any of my network printers. Network is operational and printers work from other PCs. I have tried to delete printers and re-install but nothing works, seems to be impossible to communicate.
I run windows XP SP2 on a Dell Inspiron with Norton Security. The only recent change was to update to IE7.
