Good morning. I have a client who has a SBS 2003 server that needs to be retired. I set up a 2012 std. server, joined it to the domain, and installed AD. There seems to be proper replication, which I confirmed by moving a user object on the 2003 DC and also on the 2012 DC. Each DC saw changes from the other. However, when the 2003 DC is off the network, then on the 2012 DC, ADUS will not open - says domain is not available. In the 2012 DC DNS, all records appear to be fine. I could use some guidance on this.
Thank you,
Allen
