We have an internal system that use web pages and databases for special purpose. I have 2 workstation that give give error 404 while trying to access the web pages. The user first access the pages that ask username and password, they enter it and click connect and after Tomcat show 404 page not found error. They have this problem since 2 days. It seem it is when they upgrade to Internet Explorer 8. I have 9 other workstation that have Internet explorer 7 that work fine.
I tried with firefox 3.5 and chrome and it does the same thing. I update Java on client and no change. Firewall is disable too. I desinstall IE8 and tried with IE7 but the problem is still there.
Any idea what could cause that problem. I have 2 workstation that are unuseable now because it is use for that purpose only.
