I've running into several issues with the new HP machines. I'm sending everything I've learned on the first issue (it's a major one) in the hopes that someone might have some ideas or have run into it before
OS: XP pro servicepack 2
Problem :The nc6400 laptops can't connect to anything through a wireless VPN connection. The wireless connection itself works fine. I can connect to any external websites and externally available company websites. As soon as I make the VPN connection (and it does connect) I can't connect to any external websites, internal websites, servers or anything else. Here's what I've done to narrow down the issue to the wireless card built in to the nc6400s:
An HP nc6400 wired Ethernet connection works fine with VPN.
A Dell Latitude C840 wireless VPN connection works fine.
A Dell Latitude D800 wireless VPN connection works fine.
A Dell Latitude D600 wireless VPN connection works fine.
A Dell Latitude D810 wireless VPN connection works fine.
A Dell Latitude D610 wireless VPN connection works fine.
An HP nc6400 wireless VPN connection through a Dynex wireless PCMCIA wireless card works fine.
I uninstalled and reinstalled the Cisco VPN client - nc6400 doesn't work.
I uninstalled and reinstalled the Proventia firewall software - nc6400 doesn't work.
I turned off WEP on my wireless access point - nc6400 doesn't work.
I disabled the SPI firewall on my wireless access point - nc6400 doesn't work.
I tried multiple MTU settings on my wireless access point - nc6400 doesn't work.
I disabled Afterburner on the wireless NIC - nc6400 doesn't work.
I forced the wireless NIC to prefer the 802.11 g/b band - nc6400 doesn't work.
I tested 2 other nc6400 laptops - neither work.
I wasn't able to ensure that all Windows patches were applied to our current setup since Windows Update is disabled by group policy so I erased the hard drive on my test nc6400 and reinstalled Windows using the CDs that came from HP. After getting all the patches installed it still doesn't work. This would eliminate both a possible patch problem and also any possible issue with our image and imaging process.
I contacted HP via their live chat and was told that this is an issue with the Cisco VPN client. I don't buy that as all these other laptops and wireless NICs work. I'm getting desperate
