Jabstop

Jabstop is a program freely available at software.usc.edu used to help fix network problems. Jabstop can help prevent your computer from sending network packets that might lead to your being disabled from the USC network. Although Jabstop does not eliminate all problems, it helps to mitigate network errors caused by problems inherent to certain network software such as HP JetAdmin, PC Anywhere or Microsoft Windows. It limits broadcasting and random packets in PC Anywhere and HP JetAdmin, so that computers running Jabstop will not broadcast messages to all IP addresses on the USC network when looking for a printer in a neighboring office.

If you are running Jabstop and your computer has been disabled, there might be another program on your computer that is scanning the network. The list of possible programs includes network scanning programs, printer configuration utilities, and network image distribution programs such as Norton Ghost. Most of these programs can be used on the USC network, but rather than setting them up with options such as Find server/printer automatically, set them with options such as My server/printer is at this IP address.
