SYMPTOMS
A DHCP server may fail to lease addresses or renew leases to DHCP clients after a period of time when TCP/IP is bound first to RAS.



CAUSE
When the binding order of "Microsoft DHCP Server" places the RAS binding (Remote Access WAN Wrapper) ahead of the NIC binding, and the RAS TCP/IP address is 0.0.0.0, network client DHCP packets intended for the DHCP server are ignored.

In addition, the Event Viewer may log the the following system error:

Event ID 4281, Source WINS, Description:

"The machine you are running the WINS server on does not have a valid address."

When WINS requested the system for the address, it got 0.0.0.0 as the address.

NOTE: WINS binds to the first adapter in a machine with more than one adapter bound to TCP/IP. Check the binding order of adapters and make sure the first one has a valid IP address for the WINS server.



STATUS
This behavior is by design.
