Exchange 2010 - Services won't start

Hi there,

We have an exchange 2010 DAG. On one of the servers all Exchange services won't start.

I get two errors: Error 1068 and Error 1053 depending on what service i try to start. 

I tried restarting but to no avail. Also i did a sfc /scannow and it said i have corrupted files but could not fix them. I can't update the system, the backup agent won't respond anymore, and the Exchange service is down on this server.

Is there anything i can do to avoid reinstalling the server?

Thanks.
