Answer : Problem with remote access VPN with ASA 5510

It should work with your existing transform set (DES-SHA), but try adding this one to see if your VPN client is having trouble with that transform set:
crypto ipsec transform-set ESP-3DES-SHA esp-3des esp-sha-hmac <---define the new transform set with 3DES instead of DES
no crypto dynamic-map Outside_dyn_map 20 set transform-set ESP-DES-SHA <---take off the old transform set
crypto dynamic-map Outside_dyn_map 20 set transform-set ESP-3DES-SHA <---associate the new transform set
crypto isakmp nat-traversal <---allows VPN clients to connect from behind another NAT device
Give these a go and see what you get...
