Before the current IT department came on board, there was a network set up for our Radiology department to transmit PACS images to an offsite location for reading. The problem is is that the old department has quit and there is no documentation on any of it. I have two Bay Network Bay Stack 303 switches and 2 Cisco routers on that network. We know the IP addresses of the routers but not the switches. My question is....is there software out there that can automatically scan our network and tell me all of the IP ranges and the MAC addresses of the devices that correspond with them?
