hai,

@awnish, in setup have 1 domain controller not replication issue.

@santhosh, s active account. joining process overrides existing account in ad.

finally observed one if account uisng domain join, has domain admin rights can overrite existing account. created account , deleaged create computer account in computers container. when use new delegated account join workgroup computer domain name active in ad, throws access denied. same checked domain admin account, does.

pls tell if wrong. all.
