windows xp with cisco vpn client problems

i just bought another laptop for an office user.  it's a thinkpad t42 with win xp sp1.  we have a standard windows 2000 server / domain network setup.

i've been using a cisco vpn client [v3.6.1] to access our cisco vpn concentrator with other computers, with no problems whatsoever.  as soon as i install it, i get the following responses:

     1)  i can still see other computers on the network from this laptop, but no other computers can see this one on the network neighborhood.  even the PDC can't see it.
     2)  the PDC does register the comptuer in the Active Directory, though, and shows it correctly as a winxp sp-1 computer

both 1 and 2 occur when the client is not running.  additionally:

     3)  when i'm out of the office, and run the client, i get no response.  no errors, no nothing.  when i'm in the office, it connects just fine.  [but then, of course, i don't need it in the office.]

i've reinstalled the operating system 4 times, using 3 different hard drives to no avail.  any suggestions?  i've tried getting a newer version of the client, but can't.  i've turned off winxp's firewall too.  i've also turned off the IEEE 802.1x authentication setting in the network card.

  That is why:
>i can't even ping the ip of the laptop from the PDC or any other computer on the network.  [i can ping everything from the laptop]  that's really odd.  
  Not odd at all, expected with stateful firewall checked..

You should be able to open a log window from "Log" option at the top"
or try Cntrl-L to open a log window before you hit connect..

Both 1 and 2 can be explained if the option "stateful firewall always on" is checked. This enables a stateful firewall (special build of zone alarm) to run at all times whether the client is running or not.

For #3, need more information. You might need to enable logging on the client an see what's up. The client has to do something. Does it time out, stay open, close, minimize, what?

>i've tried getting a newer version of the client, but can'
I have to ask: why can't you get a newer version? You own a 3000 series concentrator so you should be entitled to the VPN client upgrades at no cost.

just reinstalled the client.

stateful firewall is checked.

actually, i do get a "remote peer is no longer responding' message, but it takes much longer than usual.  now, i can't even get the client to connect within the office.

additional info:  i can't even ping the ip of the laptop from the PDC or any other computer on the network.  [i can ping everything from the laptop]  that's really odd.  

we have the 3000 series, but discontinued the annual cisco service, so i'm having a hard time scoring a newer client.  i'm still trying.
 
don't see an option to start the client logging.  can you let me know where it is?

Are you sure this new laptop does not have XP SP2? If yes, then you will have no choice but to upgrade the client....
