Domain Controller 1 = Windows 2003 R2
- Domain Name = MYCOMPANY (Single Label Domain)
- Functional Level > Windows Server 2003
Clients: Mix of Windows 7 Pro / Windows 10 > 100 qty
Recently we acquired licenses for Win 10 Pro (Downloaded Win 10 ver 1803). When we try to join W10 to domain, it gives error
Ac active directory domain controller (AD DC) for the domain "MYCOMPANY" coould not be contacted. Ensure that the domain name is typed correctly.
Previous version of windows 10 are joined to domain properly. but only this new version 1803 is not able to join domain.
I can ping domain controller names via effected clients. nslookup working ok.
How can I track the issue? kindly advise.
