AFAIK you can disable the firewall if you so desire, but uninstalling it means 
uninstalling XP SP2 which I don't think anyone would recommend unless it breaks 
application compatibility. What pray-tell do you use your workstation for that 
it requires more than 10 tcp connects?, this is actually a feature to prevent 
TCP Based denial of service attacks. Thus limiting TCP connects is a good 
thing, not a bad thing. 

I don't know where you got the information that it doesn't do statefull packet 
inspection but please review
http://www.microsoft.com/technet/prodtechnol/winxppro/plan/icf.mspx

Which indicates :
Stateful Packet Filtering Security Policy
The primary security policy that ICF enforces through stateful packet filtering 
contains three rules:
* Any packet that matches an established connection flow is forwarded.
* A sent packet that does not match an established connection flow creates a 
new entry in the connection flow table and is forwarded.
* A received packet that does not match an established connection flow is 
dropped

The WIN xp sp2 firewall is a serious waste of time. Aside from the lack of SPI 
it does, then you have the issue with it limiting tcp connects to 10 at a time, 
and so forth and so on, I would uninstall it.

Personally, I'd ditch the Windows firewall and set up your Sygate firewall to 
do whatever you need. Two firewalls on one box might not get along well...

Hello list,

I have windows XP box used as proxy server for my users, there are two
firewalls on it - first is win XP SP2 native firewall, second is sygate
personal firewall, for additional filtering... There is also aDSL dial
connection to the internet... After I reboot the computer, everything
works
fine...until I log on to the system...then XP native firewall simply
crash
and I can see opened ports, so I have to turn it on manually...from now
on
the firewall remains on, doesn't matter if I log off and log on
again...but
after I reboot the computer and log on, the firewall is switched off
again...can somebody advice...? I seem to be helpless, although I had
any
suspicions of any worms or viruses, but I didn' find any...
