Disabling DFS Namespace and DFS Replication services if not used?

Have a Windows 2008 R2 server that logs an error during startup from DFSR - 

DfsSvc - 14550

The DFS Namespace service could not initialize cross forest trust information on this domain controller, but it will periodically retry the operation. The return code is in the record data.

The site doesn't use DFS and doesn't have the DFS tools installed on the server. As its not used I don't follow why the server is attempting to initialize the DFS Namespace, and so will it affect NTFRS if I disable the 2 DFS services?
