Yes. Set up an Alert that monitors the Server Work Queues: Current Connections counter.
Open Computer Management, click Performance Logs and Alerts, right click Alerts and choose New Alert Settings.
Give it a name.
Now, in the Counters section, click Add, and choose Server Work Queues in the drop-down.
Select Current Connections, and choose All Instances. It will select 2 counters; I am not sure what the difference is between them.
Click Add, then Close.
Now, in the Alert When The Value Is section, choose Over and then whatever number is the minimum number of connections you want as your threshold. If you want to know when 3 people connect, put 2 in the box. On person # 3, the alarm will go off.
Click the Action tab.
If you want to see a popup error come up on the screen of the machine you are monitoring, put its name in the Send A Network Message To box. Or you can put in any machine name in that box.
Click OK to start the alert.
Close Computer Management!
Now, whenever the connection threshold is exceeded, you will get an annoying popup box telling you so!
hope this helps
