Dependency missing: Datachannel

Last friday I attempted a move of our epolicy database to a new server. I used the manual at https://kc.mcafee.com/corporate/index?page=content&id=KB66616 to move it.

After the install, I ran into several problems. Some services wouldn't start. After a while, I decided to go back to the old server. Although nothing on this server has changed, epolicy still doesn't start.

I rolled back all directories and the database to a point before the move, but still no luck.

When starting the epolicy site, I get these errors:

EPOAGENTMETA - Dependency ComputerMgmt  had initialization error
VIRUSCANREPORTS - Dependency  CommonEvents had initialization error

VIREXUB_8500 - Dependency  ComputerMgmt had initialization error
RepositoryMgmt - Dependency  ComputerMgmt had initialization error
CommonEvents - Dependency  ComputerMgmt had initialization error

For some reason, the Computermgmt is missing the dependency DataChannel.

I cannot seem to find what causes this error or how to fix it.

Does anybody have a clue about what's going wrong here?

ps, clients seem to be able to connect to the server, but since the repository isn't updating, clients aren't updating.
