SYMPTOMS
A multi-homed Remote Installation Service (RIS) server that is configured with two or more network adapters or IP addresses on the same subnet may not respond to PXE clients across a router or DHCP relay agent. Clients may receive the following error message:

DHCP..........

No reply from a server.

Press any key to reboot system



CAUSE
The multi-homed RIS server does not respond to the DHCP request to the Boot Image Negotiation Layer (BINL) service port 4011 when the server is multi-homed with network adapters or IP addresses on the same subnet and across a router from the PXE client.



RESOLUTION
To work around this problem, move the RIS installation to a server that is not multi-homed with network adapters or IP addresses on the same subnet.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
This problem can occur with PXE 2.0 clients, but older clients may work properly. The multi-homed RIS server that is described in this article may respond to clients on the same subnet but not to clients across the router. If you disable or remove the additional network adapters or IP addresses on the RIS server, the RIS clients may be able to properly connect to the RIS server.

The problem that is described in this article may occur even though your RIS server has active DHCP scopes and all IP addresses on the RIS server are properly authorized in the DHCP management snap-in.
