DNS and subnet population in Sites and Services professor_ml 12/29/2008 5:51:00 PM We have a situation at my workplace where QIP is used for the primary DNS solution. This is ran by another group within the organization. Our problem is that the DNS administrators are constantly changing subnet assignments and communications are non-existant across groups due to political influences beyond our control. In the end this results in our subnet site assignments geting out of whack with what is truly assigned (i.e subnets in Texas that should go to the DC in Texas are actually assigned to the Columbus site sending them to the Columbus DC's) Our question is this: if we setup a Windows DNS server as a secondary DNS server on one of our DC's and have zone transfers initiated from the authoritative server would the subnets that come in with their changes be refelected in the subnet definitions within the Sites and Services msc ? If we could find a solution that would allow for the subnet population to occur dyanamically within the subnet field of the sites and services msc we could then stay on top of the changes and manually make them on a weekly basis thus keeping our subnet assignments as close to real time as possible. Any help would be greatly appreciated as we continue to find a solution to our challenge. -- Mike Leslie MCSE, MCSA,MCP,CCNA,CNE

Just why the DNS admins are thinking to change always the configuration, you can not always jump around to reconfigure AD sites and services. I think you can also be happy that all DC's are still in sync and that site aware services/applications are still runnning. Get some rules form your boss and clear that on that level. Every other option is just a workaround which will not solve the real problem.
