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.
It seems like Microsoft says to use LDP.exe to remove the 2000 server from AD based on the following we page, but Our current Exchange Server has "Exchange Management Group" for the first storage group and the old Exchange server has "First Storage Group" for it's first storage group in AD. I'm thinking there will still be leftover remnants of this old Exchange server in AD. Do you think these are the instructions I should follow or is there a safer\better way? We will be using LDP.exe on a 2003R2 server and I don't know what the deal is when Microsoft mentions using LDP version greater than 3.0 could cause destruction.
What do you think?
