Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I'm trying to setup a simple ARR system. I have 1 ARR machine load balancing between 2 APP servers. I can reach the app sites if i use the server name of the ARR machine. (http://arrserver/app) But i can't do it with its IP address. ( It gives the "Bad Request - Invalid Hostname". In the ARR machine i configured the default site's bindings to "All Unassigned","80" (default values). Do i need to change the binding rule or need additional url rewrite rules? And also, in the ARR server doesn't work. But http://localhost/app works fine.

Thx in advance

Hi @quanta. The two backend servers have no Host Header Names. They are blank. –  syloc Oct 14 '11 at 13:49
How about the IP Address on the 2 app servers? –  quanta Oct 14 '11 at 14:32
They are "All Unassigned". They have the default values. Nothing configured here. –  syloc Oct 14 '11 at 19:32
