[Samba] Samba4 - global catalog (GC) cannot be contacted using Windows 7 RSAT

[Alfonso Conner]

Hi Rowland,

Currently using Samba 4.8.5
2 x DCs running on CentOS 6.10 (Final)
Configured 1 DC via classic upgrade, and the latter DC join AD forest.
Would it be alright if I were to redo the classic upgrade?
Hope to hear from you soon.

Thanks and Regards
