Cannot display Namespace on one DC/DFS Namespace Server, othes are fine...

when select namespace add diaplay following error in details pane.
                \\<domain>\<dfs root>\: namespace cannot queried. element not found

it @ point give me:
               \\<domain>\<dfs root>\: namespace cannot queried. rpc server busy complete operation.

the server i'm doing on dc (dns, wins) , fileserver , pretty idle of time.  replicates data to/from remote offices.  replication working fine between servers.  other servers/dcs can add namespace display.   there nothing in of event logs on troublesome server noteworthy

it looking @ of results of dfsdiag see dfs namespace listed as: 

\\<nt domain>\<dfs root>                \\domain\root
\\<fqdn domain>\<dfs root>            \\domain.com\root

i'm having issues clients accessing namespace \\<nt domain>\<dfs root>  though unsure how supposed access it, our without .com.  seems machines \\domain works, \\domain.com not , vise versa.

here results dcgiag.

 dfsdiag /testdcs  shows folloinw warnings:

hi,

from description, dc in problem 1 of replication targets in \\domain\<dfsroot> (the dfs namespace trying displayed). replication works fine (means data can replicated , dc) cannot display namespace. please correct me if there incorrect.

meanwhile, operation system of dc? please let know.

here article may relate issue, can have on it:
