Hi,
I noticed that when i try wireless active sync on my home network with
Exchange i have to put the full server address: "computername.domain
name" But when im trying to access exchange over the internet i have
to change the setting to "domain name" and leave out the computer name
and then it works. I know this has to do with DNS but can someone
guide me as to what to do in the DNS management. I want both option to
use my domain name only. Also i have a domain name with godaddy and
created an mx record there pointing to my external ip address. The
same thing happens over the web when i have to type
https://domainname/exchange ot access OWA. At home i have to type
https://computername.domainname/exchange

This is by design, since Windows DNS is local to your domain at home you
will resolve it by the FQDN of your computer on your home network. When you
are external to your Windows Domain you will have to resolve your domain by
the external DNS records created by your ISP, in this case Go Daddy. This
both secure and prefer method of keeping your External and Internal DNS
separate.

If you want to resolve your External DNS records internally, you will have
to add these records in DNS Manager. For example, your website A record at
Go Daddy will point to your Static IP. Create a www record for this static
ip in DNS Manager.

With RPC over HTTP, I believe the same profile should work internally and
externally - specifying server.mydomain.local should work from the outside
because of the SSL certificate and the proxy settings in OL2003.... ?
