Block .exe files via ISA server

[Bad boy Warrior]

Ive managed to block certain sites that we do not want users to access but this doesnt stop them from downloading .exe applications. Anyone know how to block these file types if were using ISA server 2004.

Thanks

Try this

Right click firewall policy rule for HTTP ->click on configure http -> tab Extensions

Block Specific Extension ( Allow All Others ) and then add extenstions you don't want your users to download.
