Solution to fix these Exhange errors?

Overview: We have an Exchange 2007SP3 server with all updates. We have a 2003 level domain\forest. We have a BSD\Linux box named "mail.domain.com" that forwards email to the Exchange server. We have cleaned up an old 2003 and 2007 Exchange server from AD and are now left with an Exchange 2000 server that is still in AD. It is named the same as the BSD box... When I look in AD, it appears to show there are no roles installed on the 2000 "mail.domian.com" server, but we get these messages in Exchange 2007 error logs which tend to say it is a Routing Group Master.


Question #3
What do you think should be done to solve these errors? We want to upgrade to Exchange 2013 in the near future.
