We are still having problems with clients losing IP addresses. The clients will time out and go to the generic 169.x.x.x instead of our 10.x.x.x network. The clients authenticate to an RSA server. The problem happens on random clients so it's been hard to catch. I did catch one and ran a packet capture on it, but can't decrypt it because no one knows how to get the WEP key off of the RSA server. I've heard from some of the TAC guys that this has happened before, but no one knew what was the resolution.
