I found this pgm annoying. I couldn't get it to do anything, then I clicked on the check-mark command button (after setting a router option) and immediately about 25 error windows popped up. It then ran for about 5 minutes "checking SNMP" so I tried the "stop scanning" button and nothing happened -- had to kill it from TASK manager. All I want is to find the IP address of my print server and a few other things. (I kinda gave up; I do it manually using the US Robotics' BIAdmin pgm)
