Hi Victor, Run network monitor or another packet sniffer on the client and you'll know exactly what the problem is.

The DHCP is not on ISA machine. Only ISA runs on that machine, it is a member server. I searched the logs and I can't see any connection attempt. Actually there is no record coming from that machine at that time; only before and after the problem. I'll keep an eye on it just in case I missed something. Thanks!
