Can't start service \"webMethods Broker Server

After the machine was restarted, the service “webMethods Broker Server 6.0, port 6849” hangs on Starting

In the app event viewer
The description for Event ID ( 1236 ) in Source ( awbrokermon ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. The following information is part of the event: d:\Program Files\webMethods6\Broker\data\awbrokers60\default, 0, 0.

Any ideas?

Thanks.
