5) Finally we will have a Update Computer Script to allow a user to

update the services for a server already listed in the system. This

allows updates to the system, for example if IIS was installed;

these running services will need added to the SQL Table for that server.

​

The execution of the Update Computer Script will simply delete

all the service entries for the server and then add the current

running services to the SQL Database table.
