Thanks.  Is the reset based on the mapped gid or the original 3000008 (original Domain Admin)? I assume it's the latter.

Is there a reason why I shouldn't map Domain Admins to a gid of 3000008 to match its current un-mapped default value on the ADC? I understand I would need to add 'idmap config SAMDOM:range = 30000-3000999' to my member server smb.conf.   Presumably this wouldn't impact sysvol, and, it would allow me to use the DA account on the member server(s).

I'm not sure I understand what you mean by starting from 500? I couldn't find the current recommended starting point in the wiki, other than if using the old ADUC ("...By default, ADUC starts assigning UID and GID numbers at 10000...". Would this be a good starting point for a new domain?

I appreciate your help!
