I have installed Windows 2003 server and created a Domain named BITM2013. Previously the server had DHCP running with the domain name bitm2009. Now whenever I am trying to join the domain the clients says "bitm2013 domain does not exist".But in a freshly formatted system its joining that domain without any problem. I have tried to get out of the previous domain by joining a workgroup and then again join back but its not working. I think I have to delete some information in the system for the previously joined domain. Or is there any other way to rectify it? Help.
