Is it a bad idea to implement a windows 2003 server into a pure Windows Server 2008R2 Domain forest with the functionality level set to 2008R2?
We have some Windows 2003 server licenses and I may be in need of using them, but am unsure on any issues that might occur. The Windows 2003 Server will act as nothing more than a member server with perhaps a few applications to allow remote users access too. I recall hearing that some Windows 2008 specific group policies wont apply to Windows 2003 servers.

If your current domain functional level is 2008 then you can not promote 2003 domain controllers.
You can join them as member servers to the domain just fine. No issue applying the GPO's.

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
Once your FFL is 2008R2 you can not add 2003/2008 Domain controllers to it, only 2008 R2. Member servers that run 2003 will have no problem in domain with FFL of 2008 R2.
