It's getting it from Active Directory. Was Exchange removed properly? How
was Exchange removed? Are there more than one server, and if so, did you
move all mailboxes, public folders, hidden and system folders, then properly
remove it?

What is the EventID# of the error? Are there any other errors in the Event
logs on the DCs? Are any of the DC multihomed?

I don't think licensing service has anything to do with it. Matter of fact,
you can safely disable that service.

To ascertain whether any parts of Exchange still exists, use ADSI Edit, and
look drilling down through each folder with a fine-toothed comb, in the
DomainNC and Configuration partitions for any Exchange objects that may
still exist. ADSI Edit is an AD editor similar to what the registry editor
is for Windows and is part of the Windows Support tools on the Windows disk.
The following should be helpful showing you how to use it. Make sure you
have a complete System State and a full C: drive backup prior to using this
tool, because any changes that are made, whether intentional or accidental,
are not reversible.

Whether Exchange exists or not, there may be an app or service running that
is still configured to query for Exchange for whatever reason. It could be
an SNMP monitoring service, or some other service installed while Exchange
was running. Read the following to understand what I mean.
