Dave, I don't know if you are aware of the tweak to disable NetBios without
editing the Registry :
http://security.symantec.com/sscv6/NetBIOS_FAQ.asp?langid=ie&venid=sym&plfid=23&pkj=VRZCCSCEFRQBCBZLSRZ
I checked my services and I already had COM+ Sys App service disabled; I
believe most users with standalone PC's can safely disable this service.
(That is, even without disabling DCOM as per the OP's instructions).
Even after you disable NetBios as per the instructions on the Symantec
website, you cannot disable the NetBios service; it is still needed for
connectivity for some reason. You would still need to block ports 135-138 in
your router after making this tweak.
