I removed the dns forwarder line as it was left over when using the
internal DNS at one point. Thanks.

I'm receiving several of these messages in my samba

either. I'm under the assumption DNS related.

I have 3 sites with 2 DC's per site. These messages are only coming
from one site and both DC's are logging the errors.
Since I suspect DNS related, I will provide my setup configs.
The message is coming from dcerpc_util.c, so it probably has nothing to
do with dns

You are using Bind, so, as the 'dns forwarder' line will be ignored, you
might as well remove it.
I think we need to know more about your set up, OS versions etc.
Also I would take it as a big favour if you found a better email client
that didn't add all the blank lines ;-)
I have 6 DC's all using Ubuntu 16.04.5 LTS. I believe I previously
indicated they were 14.04 releases. A total of 3 sites with 2 DC's at
each. Using rysnc sysvol replication as well. All DC's are using
bind9 for DNS. All DC's are compiled from tar and using 4.9.1.
I was previously using Samba 4.8.6 prior to upgrading to 4.9.1. I was
not alerted to these errors until after the upgrade.
As a side note I have been on the list under a previous email if all
this sounds familiar. I switched back to using Thunderbird so curious
if it resolves the blank space issue as well.
The issue actually appears across all sites. Not just the one I
initially suspected. I was able to capture another log event but this
time more data was with with it.
