isa server 2006

We're running a windows 2003 r2 server with isa server 2006 acting as our proxy, this is not a DC as it doesn't need to be and causes major issues if it is. Everything working fine no issues, I thought, teacher comes to me "I need to access this site but it is being blocked" thinking it is a PICNIC (problem in chair not in computer) problem I go to have a look and fair enough isa is blocking the site HTTP filter. So getting back to the isa box and going to configure the HTTP filter to allow the site I find to my horror that the HTTP filter is not there to configure, it shows in the configuration-addins- web filters but not when you go to a firewall rule. Help!!!! any ideas would be gratefully accepted. :D

ISA will block by default so if you have no firewall rule to allow the HTTP traffic it won't work. Create one is my advice ;)

Hi Rick thanks for that.

Maybe I was unclear so I apologise, the default rule for net access we have included the HTTP filter, always has, it has now gone disappeared, vanished. Hence my problem, and question how do I get it back?

When you right click and select properties on your http filter in the add-ins element is the http filter enabled and is the relative path set as HttpFilter.dll?

yep all the isa settings look fine and as I say it has operated fine since install and I had used the HTTP filter to try to block out messenger after install, so it was working. seriously puzzled :?

Anyone?? or am I looking at an uninstall - reinstall situation?

What filtering software do you use?
