Upgrade from 4.2.58 to 4.2.76 errors

I'm running a remote administration server with several hundred clients connected to it from physically separate offices.

I'm trying to upgrade clients from the .58 version to .76 to fix the BSoD from flash player upgrades. I tried a small group with a handfull of clients, which went ok. Now that I've tried to push the update to the approximately 50 clients reporting in with .58, the vast majority are getting an error code that no amount of googling has helped with.

Avsyncsrv / Ca2557 89 minutes ago Warning Upgrade processing error, error code: (7,-112)

Any thoughts?

 

Have you gone through the steps in the following KB Article, including upgrading the ERA prior to upgrading the client machines?
