Finding firewalls

I've been encountering problems connecting two computers via wireless
network, both machines running Windows XP Home. I have a sneaking suspicion
that there's a firewall lurking in the background that is blocking traffic
between the two. (I have Windows firewall on and McAfee off).

Is there a way to find other firewalls, such as one that might have comne in
with the installation of a VPN prior to networking?

Thanks,

I have seen reports of Cisco VPN client software causing issues like this.
Any chance your running a Cisco VPN client program?

Also, some wireless routers give you an option to block traffic between
wireless clients. Check your routers support site or the users manual for
possible help with that.

McAfee has been known to not completely be turned off when you turn it
off.
 
Here is an old thread concerning a Cisco VPN client and Remote Desktop
problems as an FYI...

Please not the the OP was running XP Home of both PC. XP Home does
not allow the PC to "respond" to a Remote Desktop request. XP Home
can only request a Remote Desktop from other Server or XP Pro.
 
Hi
In many cases Firewall Off, does not mean that it is Not Running something
in the background.
Sometimes the only solution is to totally uninstall.
Download this and see what Processed are running.

If you see some thing related to McAfee you can "Kill" the process and see
what it does.

Yes, but XP Home can run the Cisco VPN client. I was just at a client's this
morning where that is the case. And the Cisco VPN has a stateful firewall
option that will block LAN traffic. And that is why I was at my client's
this morning, to uncheck that option that somehow got reselected after an
update of that program. So maybe the OP has something similar.

Your right of course...

The OP did mention VPN so I interjected the possibility that Cisco VPN
client software could be a possible source of the problem based on past
threads where that software caused other issues with networking type
software, ie. like RDC for example.

So until we hear back we are all in the dark so to speak.
