Hi,

I am in the process of going from exchange 2003 to exchange 2010 (then 2013) but my AD still has an Exchange 2000 in it, even when you look in exchange system management on the 2003 box you can see an entry for the Exchange 2000.

The exchange 2000 server does not physically (or virtually) exist but it is still a computer in AD.

How can I safely remove all traces of this exchange 2000 server? I assume I cant just delete it from AD and thats it.

that kb article doesn't apply
it refers to manually removing services and registry entries which of course you can't do since you stated the server no longer exists

you need to remove from AD manually using ADSI Edit

open ADSI Edit then right click ADSI Edit on the left and select connect to
under 'select a well known naming context' choose configuration then ok

expand CN=Configuration then CN=Services
then CN=Microsoft Exchange and CN=<your org name>
then CN=Administrative Groups then CN=<exchange admin group> and finally CN=Servers
under that you should see your 2000 and 2003 servers
right click on the 2000 server object and delete it

you can also delete the computer account from AD though the steps above will remove from the Org and won't show in ESM and won't cause an issues when you move to 2013

The article linked doesn't talk about manually removing the services and registry entries it says how you can remove an Exchange 2000 organisation from AD by running update.exe /removeorg from Exchange 2000 SP2 media. It's more or less doing what you are suggesting without using ADSI Edit.

Too many email signature updates to deal with?

Do you feel like you are taking up all of your time constantly visiting users’ desks to make changes to email signatures? Wish you could manage all signatures from one central location, easily design them and deploy them quickly to users? Well, there is an easy way!

the beginning of that article clearly states:

Note This procedure will completely remove all instances of Microsoft Exchange 2000 Server and of Microsoft Exchange Server 2003 from Active Directory.

the objective here is to remove the server, not the entire exchange organization

if that were executed here the user would have a non-functioning 2003 server

Important Do not use the removeorg option unless you intend to remove Exchange completely from your organization.

Important Make sure that there are no Exchange 2000 mailboxes, Exchange 2003 mailboxes, or any other functionality being used on Exchange before you run the removeorg option.

My bad - apologies. Since you already have other Exchange servers in your Org, using ADSI Edit is the safest option.

that first link has additional references that assume the server is still online by moving components elsewhere or details on removing exchange attributes from user accounts

the second link applies to exchange 2007 and assumes the 2000 (or 2003) server is still physically present
