9986 errors Installing SCOM 2007 Agent to Exchange 2003 SP2 Clusters - Day, Brian

Can anyone shed some light on deploying SCOM 2007 Exchange 2003 Management
Pack to monitor Exchange 2003 SP2 clusters? I installed the SCOM agents to
the machines, then the management packs, and then went through the
management pack config wizard.

Everything appeared happy except for the mailbox servers, which are
active/passive clusters. The front-ends, bridgeheads, SRS, public folder
servers had no issues.

The only errors during the config wizard were 8 pairs (We have 8
active/passive clusters) of these.....

Error: Cannot configure the mailbox access account on computer 'Active
Node'. This configuration can only be made after the Exchange MOM event 9986
is registered by MOM.
Error: Cannot configure the mailbox access account on computer 'Passive
Node'. This configuration can only be made after the Exchange MOM event 9986
is registered by MOM.

This pointed me to...

..., but for the life of me I can't figure out what to do at this point. it
seems like all the documentation so far is for MOM 2005 on this issue.

In SCOM none of the mailbox servers show up under Back End Servers. The
agent is installed and lists the boxes as healthy, but it is like SCOM
doesn't realize Exchange is running on them. The servers themselves are
running a mix of Windows Server 2003 Enterprise SP1 and SP2, but any given
cluster is all SP1 or SP2, no mixing.

The articles keep saying "if Exchange is not installed", but Exchange is
definitely installed and running on one of the nodes of each cluster. I
would kind of understand if the passive node fails, but they both do.

The Windows Cluster Mananagement Pack is installed as well, but the Exchange
virtuals aren't showing up anywhere either.

Thanks everyone!
