The control program uses 11.7 MB of disk space and requires 3 MB of memory. I didn't need to configure each PC manually to control it remotely via modem. For sites that have multiple servers or clients requiring periodic monitoring, PC Duo has a useful scan operation that displays selected client PC screens one at a time in a dedicated window. A dialogue box displayed the connected clients for the scan operation and let me choose a scan interval. If this tool could stop monitoring and focus on a problematic client based on an event or SNMP trigger, it would make an ideal sentry to monitor multiple servers from one console.
Helpdesks often use remote control to show users how to engage an application or perform a function.
This proves futile, however, if the helpdesk is not familiar with the client desktop. It may be more efficient for helpdesk staffers to use their PCs as examples. PC Duo enables control PCs to display their screens to individual clients or to an entire group. To end the session, support staff resumes a control session. This requires a control PC to install the client application.
