Some background first: So I have two domain controllers (dc1 and dc2) running Server 2003 32-bit and 64-bit, respectively. They have not been able to replicate since sometime in 2012 which I hadn't realized when I started working at this company. Employees were still able to log into the file shares hosted on both domain controllers so I was told not to touch them. I added a VM running server 2003 to act as another domain controller to replicate with dc1 who holds the FSMO roles.
That VM recently died and I removed the AD role from that VM from dc1. Now I cannot log into dc1 using the Administrator account. I also cannot add any machines to the domain. Some users can get to the file shares on dc1 but most people can't. I ran dcdiag on both dc1 and dc2 and the results can be seen here.
So, my question is, is there anything I can do to get dc1 back? I'm not even sure where to start and I don't have anyone else but the internet to ask for help. I know I should remove AD from dc2 and re-add it but I don't want to do that while dc1 is in its current state of unrest.
