SYMPTOMS
When you use Microsoft Windows Server 2003 Automated Deployment Services (ADS), and you run the RAMDISK-based Deployment Agent on a remote computer, the Deployment Agent may not negotiate or complete a DHCP lease with some third-party DHCP servers.

Note A remote computer is named a device in ADS.

If you perform a network capture, you see repeated DHCP REQUEST packets that are sent from the system that is running the Deployment Agent. The DHCP server responds with DHCP ACK messages.



CAUSE
This problem may occur if the DHCP server does not include renewal or rebind time parameters in the T1 and T2 fields in the DHCP ACK message.

The Deployment Agent includes a DHCP client. When you use ADS to start a Deployment Agent on a remote server, the Deployment Agent DHCP client requests an IP configuration. However, the request does not include parameters that prompts for the T1 and T2 values. Therefore, some third-party DHCP servers respond with a simple DHCP ACK that does not include the T1 and T2 values.
