DFS in DR

-

my customer has windows 2003 file services implemented using dfs namespace distributed between primary datacenter , replica in disaster recovery datacenter (san replication used) , installed on domain controllers in both sites,

customer tried test disaster recovery , disconnect primary datacenter, while testing dr found when try open dfs console in dr dc got error message “the specified domain either not exist or not contacted”

is there dependencies on of ad fsmo roles located in primary datacenter?

or can issue?

regards,

maged

hi maged,

this is because "pdc cannot reached or not available".

the dfs mmc's require connectivity pdc in order management of dfs. domain-based dfs stores namespace information in binary blob attribute in ad called 'pkt'. since single attribute, it's necessary force standard management tools go single dc editing purposes. otherwise if had 2 admins editing dfs @ same time, on 2 different dc's, admin saved last overwrite changes made other admin when replication converged.

thus should prepare file server instead of running dfs on domain controller pdc.
