I realize this is more DNS related than ASP, but I&#039m having trouble getting direction on this. I want to have my site allow people to enter xxxx and instantly get xxxx.mydomain.com as their own "personal" domain name. I&#039ve seen this on several other sites, but I have no clue how to do it. I know it has something to do with running my own DNS server and creating entries on the fly, as well as creating host entries in IIS on the fly. Can someone please direct me to some more concrete information, specifically the dynamic DNS stuff?<BR><BR>Thanks
