My main address (http://allalias.com) resolves; however, for about 40% of users, you can’t get beyond that with addresses like http://allalias.com/affiliates, and even more users can’t access subdomains such as http://forums.allalias.com (while these addresses do work for a lot of people a lot of the time). I’ve turned subdomains on in WHM, and tried restarting Bind and the server numerous times (this sometimes helps temporarily). So I’ve had to use the IP to get around this, directing people to http://69.93.148.130/forums/ and similar addresses, and this seems to work. However, this is really annoying (at first I thought this was just a temporary thing while the changes in my nameservers propagated, but this has now been going on for well over two months). How can I fix the problem and be able to use my domain name for all users? What am I doing wrong?
Thanks in advance for your advice
