.SYNOPSIS
SCCM client health check and repair

.DESCRIPTION
This script will check components used by the SCCM client 
and if an issue is found it will attempt to fix the issue.

1. Looks to see if the client is installed, if not it 
will install the client from the specified location.

2. Next the script will check the startup type and status 
of services needed for SCCM

3. Runs specific client actions to verify they are working

4. Checks to see if basic WMI queries are working and that 
the SCCM name space is working. 

5. If an issue is found that can be resolved by reinstalling 
the SCCM client this will happen last. The script will also 
look for any remaining client files and remove them to be sure 
there are no corrupted files left behind.
