Terminal Server 2003 in a 2012 Domain - Issues

Hi All,

We are planning on upgrading our domain and forest from native 2003 to 2012. We have 2 x 2003 Terminal Servers and aren't planning on upgrading them to 2012 RDS for another 1 year or so. 

In your experience, will the 2003 Terminal Servers continue to function normally in the 2012 domain? Any known issues? Hot Fixes needed?

The terminal servers are: Server 2003 R2 Enterprise 64bit SP2.

Any advice is appreciated.

Thanks in advance.
