[Samba] samba-tool drs showrepl shows WERR_BAD_NETPATH

Hello there,

I have a problem with replication between two domain controllers, dc1 
and dc2.
Distribution: Debian 8.5
Samba-Distribution: sernet-samba 4.3.11-14

The replication on dc2 working fine without any failures.
But the synchronization on dc1 gives the failure "WERR_BAD_NETPATH".

Because the message "BAD_NETPATH" I checked the DNS-resolution:
=========================================root at dc1:~#host dc1
dc1.mydomain.uni-frankfurt.de has address 192.168.151.230

root at dc1:~# host dc2
dc2.mydomain.uni-frankfurt.de has address 192.168.151.231

host -t SRV _kerberos._tcp.mydomain.uni-frankfurt.de
_kerberos._tcp.mydomain.uni-frankfurt.de has SRV record 0 100 88 
dc1.mydomain.uni-frankfurt.de.
_kerberos._tcp.mydomain.uni-frankfurt.de has SRV record 0 100 88 
dc2.mydomain.uni-frankfurt.de.

root at dc1:~# host -t SRV _ldap._tcp.mydomain.uni-frankfurt.de
_ldap._tcp.mydomain.uni-frankfurt.de has SRV record 0 100 389 
dc1.mydomain.uni-frankfurt.de.
_ldap._tcp.mydomain.uni-frankfurt.de has SRV record 0 100 389 
dc2.mydomain.uni-frankfurt.de.

Solved!
For all who have a similar problem with replication:
===============================I had a look to the /var/log/samba/log.samba on
both servers, dc1 and
dc2 and I found out,
that the DNS update failed on server dc2 sins a time where the dc1 
really was not alive.
This would be normal.

The failure is that DNS update has not working forward again, when the 
dc1 was back into the network
and was alive again.
This my be a debility in Samba and the developer could have a look about 
this...

I could fixed it, with a reboot from dc2. Now it is working!

dc2 in /var/log/samba/log.samba:

Samba ships a tool named "samba_dnsupdate" which is responsible to
push
that kind of DNS updates to create needed (by local DC) DNS entries.
This script is run at samba start up, at samba installation too and can be
launched manually.

According to what you wrote I expect there was some issue when joining that
second DC which made DNS entries to not being created but I can completely
wrong as others reasons can father such issue (renaming that second DC for
example).

Anyway as you mentioned a simple restart of Samba could solve that issue.

More: if your DCs are using themselves as DNS resolver and they are using
Bind+DLZ as DNS back end, these DNS entries will be created even there is
only one DC up. This because resolver is localhost so samba_dnsupdate will
send DNS request locally to know which DC is SOA (SOA is "where to write
updates") and as Bind+DLZ knows it is multi-master, every Bind+DLZ will
reply to such request "I am SOA". In other words samba_dnsupdate will
use
local DNS service to update local LDAP DB, no need of a second DC to be up.

I'm not really sure that modifying Samba's code to make Samba DC to
launch
that samba_dnsupdate tool periodically is really needed as changes on DNS
related to DC should not happen too often and because checking DNS entries
related to a newly added DC should really be part of the tests done by
admins after installing a new DC as AD is relying on DNS so much...
Then once they spot some issue, if they are lucky they would resolve that
issue in only one command which should not be too much, in my own opinion ;)
