Any Other Way ?

I am fortunate to have the system noted in my signature for simming. It is stripped down to a bare minimum with only FS-Related and security items and a shared cable internet/network connection. It is networked via the network facility that comes with XP Home to another PC which has all the other applications I use plus a printer.When flying with significant clouds, I am getting 15-20ish frame rates but also a once-a-second stutter which I traced back to what I presume is network polling on my Sygate Personal Firewall. With that disabled, all is smooth.I know I can turn off the firewall manually - although I hate to be without it. I know I can use Ken Salter's application to automatically turn it off and restart when finished simming.Are there any other options - for example the XP firewall? Another firewall?Thanks
