It seems to me that you have the option MANAGEDServices set to
'managedservices schedule'
or 'managedservices schedule webclient' in your dsm.opt file. If you specify
the schedmode=prompt option, the server prompts the CAD when it is time to
run the schedule. The scheduler will connect and disconnect to the server
when the CAD is first started.

If you just want the server to contact the client as specified in SCHEDMode
PRompted only then either REMOVE the MANAGEDServices option or rem (comment
it out).
