I have just installed a SBS 2008

when i want to access webmail from a workstation

i type remote.domainname.com.au/owa

i get page could not be displayed if i try this on the server it works

i have downloaded all the latest updates using WSUS

if i ping remote.domainname.com.au from the workstation i get a reply back with the public static IP not the internal server IP


why i want this to work is because when i setup there iphones to connect to exchange and when there in the office and connected to wireless they can still get the emails from the server without having to switch to there 3G

Seems like a DNS issue but SBS 2008 make a remote.domainname.com.au record with the internal IP already so im not sure what needs to be changed or updated

Hi,

If the dns server on your SBS has a zone for remote.domainname.com.au  with the internal ip address (this is realistic because it works on your server).
The problem is the workstation is not getting this DNS server, make sure the DHCP server gives the dns server from your sbs. (If your wireless access points uses its own dhcp then make sure the dns server here is also pointing to the sbs server dns)

To be sure the right dns server is used do a ipconfig /all on the workstation and put the output here

Your server is 192.168.0.200 ?

If that is true then however is a problem with you server dns, can you post a screen print of the  remote.domainname.com.au and the records that are in this zone

if Internal only then try connecting directly to the server.
http://servername/owa

What is the DNS suffix that shows in the IPCONFIG /ALL?
That should be the DNS name that you should be seeing your server on.

Then you don't really have a problem except that your DNS is not configured to support your infrastructure design.

Do the split DNS zone setup as mentioned above, did you try accessing the site using the DNS Suffix that is returned from the IPCONFIG /ALL command?

It looks like you manually added external dns servers to your dhcp server. This will wreak havoc with SBS. SBS and other AD domain controllers should be the onky dns servers clients use. It explains why clients are getting the external IP.
