I have a small-business network with 30 Windows XP machines on a single subnet and in a simple workgroup, not a domain. I would like to put a process in place that scans the network for writable shares. There is only one machine on the network, the file server, that should allow write-access. If there are any other machines that open up I would like to find out about it.
I intend to run the scan daily. I have a Ubuntu machine running Nagios on the network already so the solution could be run from a Windows or Linux environment.
