According to my very knowledgeable server support guy, ISPConfig corrupts the named.conf file by adding an invalid character to it every time a DNS zone is edited. This of course takes the bind down, making it impossible for the site to resolve properly. So this looks like a bug, we've struggled for three weeks (a nightmare!) to find out why the freaking site was not showing. The developer's may want to make a note and check on this. Great open source software, although it's convoluted (IMHO) when it comes to DNS settings. Too many settings in non-intuitive places that make configuring DNS a problem. Also, couldn't see manual or tutorial that really covered this. Most of the time I didn't know if the value to be entered was the IP or the nameserver as in "ns1" or whatever. Also, in certain fields it's hard to tell if that should be a domain name or an IP or just a title.
