Internal domain: prc data local Error
 I have a Live Communication server 2003 up as well as working throughout, but I am not able to communicate with WWW server at my ISP. Just how to appropriately correct this? I currently have been operating SBS2003 Premium, Client is XP Professional. I make use of the guidebook, “How to install Office Live Communications Server 2003 on a Windows Small Business Server 2003 network. The issue started out after I launched a new "lookup zone" in DNS. This particular zone with the title of my external address prevents the connection to the domain utilizing this address:
"Internal domain: prc-data.local"
"External domain: prc-data.dk"
I am unable to hook up with www.prc.dk at my ISP. Just what exactly am I carrying out wrong when making a new forward "lookup zone" in DNS?
In DNS you will find there is a forward "lookup zone" known as pmc-data.local and I made a different one called pmc-data.dk and with this zone I made the files for the _SIP protocol. Any sort of tips?
