Win7 Wireless Connect Looses DNS

I am working on a new HP 4415s laptop running Windows 7.  I built this laptop from scratch and updated all drivers, firmware, etc. before sending it to the end user in California.  I tested both wired and wireless connections for both plain Internet access and IPSEC VPN access using the Shrew client.  Everything worked fine when I boxed it up and shipped it out.  Everything was still working when the user opened the box and began using it.  After three days however, the wireless connection failed and I cannot get it working again.

This is the third laptop to experience this problem.  The other two began working after removing the Shrew VPN client.  I'm convinced this is not a Shrew issue based on the many posted of a similar nature I've found on the net.  Basically, the wireless adapter cannot see (or stops responding to) the DNS server provided by DHCP.  Assigning a static DNS address does not help.  When the laptop boots up without a wired LAN connection, the wireless connects to the WAP but indicates that only local access is available, and that the DNS server is not responding.

I have tried everything I can think of, and everything I can find on the net, including the following:
1) Disabled IPv6 on both the wired and wireless adapaters
2) Flushed the DNS cache
3) Disabled Symantec Endpoint Protection
4) Removed Skype (the last application installed before wireless stopped working.)
5) Ran Windows Update

Based on what everyone else is reporting, this seems to be a common issue with Windows 7, but I have not found a concrete solution yet.  The results of ipconfig /all are below.  I've also attached a screen shot of the network window when only the wireless is connected.  Can anyone offer a solution on this?

Thanks,
Joe

What kind of wireless router are they using?  Many older routers or even fairly new routers don't play well with Vista/7.

FYI....I had the exact same issue when we had two Vista laptops and an apple laptop connecting to a Netgear G.  Tried blaming it on the apple, but after upgrading to a more recent model router the problem was fixed.

Unsure about the model of router, but it was working for several days before it quit.  It was also working at a public Wifi hotspot but now doesn't work there either.  One more thing I tried was to disable the computer browser service, since one post indicated that legacy NetBEUI could be causing the problem.  Again, no change.

Can you toss a pcmcia wireless ethernet card in to test and rule out the onboard card?  Always good to start with layer 1 and work your way up.

We've moved on to other solutions to this problem.  The Shrew client definately causes problems with DNS resolution, but I can't find any information on why or how.  On one laptop the DNS goes away if the Shrew client is installed and the user enables Bluetooth.  Turn off Bluetooth or remove Shrew and the problem goes away.

We've stopped trying to get Shrew to work and have purchased the Safenet client.  Unfortunately, this has presented other problems, including the fact that it will not work with the previous Safenet policy file.  But that's another story...

We have worked with Safenet support and THINK we have a repeatable solution.  My recommendation is to use XP Mode and install the old client if you really need IPSEC on Win7!
