Hi all,
I have installed both SSRS 2008 both SQL 2008 on Win2k3.
My server is going to work as a web reporting application.
I have a problem when I try to login into SSRS Report Manager (RM) from my
office network which is behind firewall, RM shows multiple times login prompt
with no consideration about that login information is correct.
WHen I access RM by Internet out of my office network everything works like
a charm so, I need help in order to find what's wrong.
I read event log in order to find the reason why prompt appears a lot and I
found the following data

Event Type: Failure Audit
Event Source: Security
Event Category: Logon/Logoff
Event ID: 537

This issue happens if I acess RM using IExplorer beacuse if I use firefox
nothing happens.
In addittion, I already configure Internet Explorer security in order that
Internet Zone always ask login information.

Any one can help me, please?
