[Samba] 'RPC Server is Unavailable' when updating GPO

[gespi via samba]

Hi,

Researched the forums before posting but was not able to find solution to my
issue. Could be a unique problem.

GPO's are not being applied to users and computers because 'RPC is
unavailable'. The GPO's were being applied before, but not sure what
happened. Started noticing this once I binded a new instance of Windows 10
to the SambaDC and the machine nor user were picking up the GPO's. When I
run gpupdate /force there is no error given but when right clicking on the
OU and running 'Group Policy Update..', it shows failed and the RPC error
mentioned above. Has anyone ever experienced something like this?

Any help would be appreciated.

I think you would have to start looking at a network trace to
understand who is refusing what exactly.

I'm assuming this is something that is trying to trigger a process
directly on the client?  

I realise you probably don't want to set up one just to test, but the
question that comes to mind is:  Is it a Samba issue, or does this
happen in a Windows domain also?  Is there any communication with the
DC?

I failed to mention this morning I restarted the samba server and that error
did not come up once I ran 'Group Policy Update..'. But after a few minutes
the RPC error returned. Figure this could be a samba issue as it was working
on restart. The client is part to the Domain and able communicate with samba
via ping. And i am still able to add additional machines to the Domain
regardless of the RPC error

Sometimes the error is related to DNS issues. Not entirely sure why, but
I have seen it come and go.
