Check for an existing CCMexec service before ccmsetup.exe executes.
Problem: On the client machine, CCMEXEC service is already running, the client is in a healthy state. Then a GPO or Client Push happens, ccmsetup.exe starts and breaks the client communication. The client ends up getting an error stating "another instance of ccmsetup.exe is already running".
Question: Could you have ccmsetup.exe check for the ccmexec service and quit if the ccmexec service is running?
