GPO-supplied Windows Firewall config no longer being applied

I created a GPO some time ago which included some Windows Firewall
exceptions / ports etc. which worked perfectly for months.
Recently, I noticed that they were no longer working (due to an application
on another machine which requires some firewall opening suddenly stopping
working properly).
For a while (just to get it working) I simply stopped the Firewall service
whenever I was using the app (I know it's lazy but it's a home/techies
network anyway!) but now I've started looking at fixing it properly, I'm not
sure what exactly's causing the issue.
From a standard boot, if I start WF locally and look at the exceptions, itdoesn't list any GPO supplied exceptions, only locally created ones.
However, if I run "gpupdate /force /target:computer" on the machine, all the
correct GPOs are assigned and all starts working again. I basically have to
do this each time to get the ports open.
I've run the RSOP wizard (this is on an SBS2003 network FWIW) which
indicates that the GPOs in question don't have any problem. The only GPOs
that aren't listed as applied are those that this machine is out of scope
for (only related to 802.1x certificate stuff for my wireless machines).
Nothing in the eventlogs at either end that I can see related to GP.
Anyone have any suggestions as to what the issue could be?
Regards,
Paul
