My bet is that the problem has nothing to do with Tomcat and has to do with
an interaction between the firewall and the OS. I would check to see what
Windows Updates are installed on the machines. Also, check the versioning on
the firewall software. My guess is that it isn't a hardware problem if it is
on multiple machines. My guess is that the software patch levels and
versions are probably different on the working and non-working systems.
Note, 3rd party firewall products many times fail everytime Microsoft comes
out with updates/Service Packs. These products most likely install low-level
drivers which are running in kernel mode. Hence, when a bug occurs, it
crashes the whole OS which causes the system to reboot.
