Different Monitors connect to the Station from different monitored
computers but they have the same Computer ID (as
shown below.)

I cant differentiate which computer is which.
Cause:
When you were generating
the Monitor, you specified that the Monitor will
be installed on one computer.
The Monitor reports
the Monitor Identifier you specified, instead
of the computer name, if it is set to be installed
on one computer.
Solution:
1
Deactivate
the Monitor on all the computers it was installed
on
2
Generate
a new Monitor.
Make
sure you select that the Monitor will be installed
on several computers when generating the Monitor.
3
Install
the new Monitor on all the computers you want
to monitor.
