Hi,
We got 3 DCs - 1 of Win 2008 R2 & 2 of Win 2012 R2
Names of DC
WIN2008R2 - MDC
WIN2012R2 - BDC & ADCP
Problem is if we disconnect the Win2008R2 DC, all the servers cannot logon to domain. All our exchange server fails. Upon connecting the W2008R2 DC back, everything works fine.
DNS Config on all servers are pointed to W2012R2 DC Servers
