Windows Firewall was not introduced until Service Pack 2. There was, however, a firewall included in Windows XP RTM; it just wasn't enabled by default.
Windows 2000
C:\Windows\
'C: Windows: System32' is the default location of 'cmd'.
c:\windows\system32
The default log file name is Pfirewall.log.
Windows 98 does not include a firewall.
Yes, Windows 7 comes with Windows Firewall in the OS itself.
Is the Windows Firewall enabled, or any other Firewall installed and not configured?
No, it doesn't conflict at all with Windows XP SP2's firewall. It actually takes the place of it. It's actually integrated into the Windows Security Center. I have been using Comodo Firewall Pro for over a year and I haven't had one problem with it whatsoever. It's earned the highest rating in default configuration and is even better than Norton and McAfee Firewalls. Best of all, it's FREE!! You can't beat that!! When you install Comodo Firewall Pro, it will automatically disable the Windows XP SP2 Firewall.
