DNS problem with Exchange setup on internal domain

[Kyle]

I have set up Exchange on our domain. It will only be used for internal mail and not for external. My problem is DNS related i think.

 

If i type the IP address into browser for OWA ie; https://192.168.1.1/exchange it resolves tot he OWA web page. If i type https://servername/exchange it tries to look outside the domain. I have added the MX record int two firrefent ways, once as just the server name and once as the FQDN and neither seem to work.

 

I guess i have missed something stupid but i am new to Exchange.

 

 

Any ideas?

What does nslookup return. Is it using your internal DNS server and if it resolves an external ip what is it / where does it go.

If you try to ping servername was address does it resolve to?

NS Lookup comes back withthe correct server name

 

 

Ping does exactly the same

How is your browser configured, are you trying to go through a proxy or via a direct connection. If its via a proxy does this have any caching/routing that may be effecting it. Also have you checked that your hosts file on the computer has not been tampered with as this could send the system to a different address than the one specified in DNS.

 

You might also want to try connecting to it without the browser using telent, that way you can see if it connects. telnet servername 80
