[Samba] Can't connect after Ubuntu 18.04.1 Upgrade???

[Thomas Rieff]

Thanks for the replys... 
Just a basic samba server...being accessed by windows 7 to the gc and tmr shares with \\10.10.171.9\gc and \\10.10.171.9\tmr 
This has been running for a year without any issues...till the update yesterday afternoon :-( 
The file server is Ubuntu 18.04 and there was an update to Ubuntu 18.04.1, which I thought would be a mild step. 
The current version of samba is... Samba version 4.7.6-Ubuntu, don't know what it was before, thought it was up to date??? 
Below is the testparm and the dump of configurations. 
Also, I do see an error in the one log below. 
Hope all is well.
