Hello list I have a case open with Microsoft regarding this, but since is taking too long I decided to ask all of you to see if somebody have an idea. In one of my offices, on the front array (between Internet and DMZ) I have different web sites published, but there are one that is causing problems, and is really weird. Basically, from "some" (just some places) when you try to access www3.interlink.bz you receive an error message (I believe is an 11004), but from another places you can access the page without any problem. The point is, I'm seeing on the ISA trace, that when the connection fail in the protocol column appear "http" instead of the regular "HTTP", I know that can sound stupid, but why just when it fail the protocol appear with lower case, ISA should be talking about a different protocol no the regular HTTP I always use for port 80. Any idea?? Regards Diego R. Pietruszka
