Error description
The Windows DHCP client sends a DHCP Discover message containing both "option 77" and "option 55 (Parameter Request List)" as the requested options to AIX DHCP server and expects AIX DHCP server can return the values of the requested parameters back to the client. But the Windows client receives the unexpected the value of "option 77" is returned (echoed) back by AIX DHCP server in the DHCP OFFER and ACK packages while the values for other parameter options returned by the AIX server are correct for the user class. For some reason this unexpected "option 77" returned by server prevents Windows client from setting any of the other options and causes Windows clients to lose their entire IP configuration and disconnect from the network.
