Hi I have ISA on Windows 2000 server. i have created a rule to stop all downloads for some users. But when I check any download in microsoft site, it shows page not found but when i try in Symantec.com to download intelligent updater with the file extension "exe", it downloads. Also, experienced recently, trojan virus has dropped some exe files in hard disk when user browsed some malicious site. Could anyone help how, exe files downloaded by malicious site and how ISA allows symantec virus signature to download when it does not allow download in microsoft site. I would like to solve this issue and therefore, request someone to help RAJU
