Is it ok to keep Windows 2003 member servers in a 2008 R2 Domain/Forest? I cannot upgrade my servers they do not meet the requirements for 2008.

Hello, no problem with that. As long as you not try to promote them to DC, as this is not possible with functional levels set to Windows server 2008 R2. Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

Hi, Functional levels determine the available Active Directory Domain Services (AD DS) domain or forest capabilities. They also determine which Windows Server operating systems you can run on domain controllers in the domain or forest. However, functional levels do not affect which operating systems you can run on workstations and member servers that are joined to the domain or forest. For more information, please refer to the following Microsoft TechNet article: Understanding Active Directory Domain Services (AD DS) Functional Levels http://technet.microsoft.com/en-us/library/understanding-active-directory-functional-levels(WS.10).aspx Regards,Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
