Incident Persister and/or Detection Server Controller service(s) on Enforce or Detection Server Service on Detection Server will not start.

If you're having problem starting the services mentioned above, check the log file related to that service and look from the following error:

Error:
INFO   | jvm 1    | 2010/03/18 06:43:58 | com.vontu.util.software.NoVersionException: Version file path not specified

If you do see this error, it could mean you're missing the manager.ver (Enforce) or monitor.ver (Detection Server) file in the \Protect folder in Program Files area.

If the file is there, verify the account launching the DLP services has access to read/write to the .ver files.
