I am running BE 12 with service pack 3 and I just applied hotfix 323893 and the DLO admin service won't start.
I get the following in the event application log:

Description:
Database exception caught at line 460 of shadow\Server\consolesvc\consolesvc.cpp with error code 0x80040E14: ADODBError-_com_error: foundationerror=80040e14, comerr=80040e14, nativeerror=4294967295, conn=, query=, msg=IDispatch error #3092, src=Microsoft OLE DB Provider for SQL Server, desc=Directory lookup for the file "C:\Program Files\Symantec\Backup Exec\DATA\BE_DLO.mdf" failed with the operating system error 2(The system cannot find the file specified.)..
I've checked and the file it mentions (BE_DLO.mdf) does exist in that location.
