DCM is case-sensitive! Having said that, what aspects of DCM are case-sensitive?
DCMCmd.exe –cfg <manifest file name> -dat <output file name> -p WMIEvents:Enable NTEvents:Enable
All the switches are case sensitive. If you type a wrong case, you would recv an error with the syntax information. Hence the DCM Solution has a handy bat file in the same folder as the Command line wrapper folder. Its called RunDCM.bat. I would suggest the use of that file. In that case you don’t need to bother yourself with the syntax. All you would be required to do is type: rundcm.bat <manifest file name> <output file name> and it would fly!
