So I inherited this system but I didn't set it up. My boss came to me with a problem. He's testing the http proxy setup that a user outside our network would use to get setup using outlookAnywhere.

I have 3 servers.
1 ncsbcs2 = Hub Transport/mailbox
1 Thorim = Mailbox
1 Hodir = Client access
Our OWA site and OutlookAnywhere works for internal network or vpn'd users. OWA works externally. OutlookAnywhere isn't working externally.
So i did some quick research and pulled up the OutlookAnywhere config via the command shell. Here is the config.
"ServerName : NCSBCS2
SSLOffloading : False
ExternalHostname : webmail.ibts.org
ClientAuthenticationMethod : Basic
IISAuthenticationMethods : {Basic}
MetabasePath : IIS://NCSBCS2.ibts.org/W3SVC/1/ROOT/Rpc

Couple of things I see right off the bat.

1. ncsbcs2 isn't a client access server. I don't know why it's in this config, except that over time the rols of these servers have changed. Maybe it used to be the only mail server and had all of the roles on it? I'm afraid to try removing it from the config for fear of messing up the system.
2. In the ncsbcs2 portion, the externalhostname setting says webmai.ibts.org but it should be webmail2.ibts.org if anything. I think this might be the problem my boss came to me with.
I found this article on how to set the external hostname for outlook anywhere.
http://technet.microsoft.com/en-us/library/aa996902.aspx
I tried to follow the EMC section but when I go to server configuration, the only server listed there is Hodir, and it already has the correct external hostname configuration.


So I went to this site to test the config in general


www.testexchangeconnectivity.com


and the test came back like this..

Attempting to locate SRV record _autodiscover._tcp.ibts.org in DNS.

The weird thing is it is working to some degree, I think inside our network.


My goals are these..


1. How do I remove ncsbcs2 from the autodiscovery config, because it doesn't belong there.


2. Where do I start to fix the rest of it?  It looks like I'm missing some DNS records or something.


Any help is greatly appreciated..
