Subject: s4: Cannot demote DC 

I am trying to demote a DC in Samba 4, but am encountering an error and cannot successfully demote any of the DC's. Does anyone know what is going wrong? 

The first time I had it choose its own partner server and received NT_STATUS_IO_TIMEOUT: 

root at peads1:/usr/local/samba/bin# ./samba-tool domain demote -Uadministrator --password='password' 
Using BLADS1.ad.domain.com as partner server for the demotion

raise drsException("DsReplicaSync failed %s" % estr) 

The second time I specified a server (a short MPLS hop away), and encountered the same error. 

root at peads1:/usr/local/samba/bin# ./samba-tool domain demote -Uadministrator --password='password' --server=BRSAD.ad.domain.com
