Hello. I have a windows server 2003 and on it, I have an IVR Software. keep in mind that this software is old and does not work on newer OS. Due to security concerns I had to disjoin the server from the main domain. With all of its SQL data and Authentication properties. Now I can't authenticate on the software for some reason and I don't know what to do. I need to be able to use my IP, Username and Password to connect to the software from a domain PC. I don't think there should be a problem with this. So if anybody know what the problem can be, please help me. Also I have tried disabling antivirus and firewall and I know that I can ping the Server 2003 which is now a workgroup system.
