Action


Result
The DHCP server is not working. You find that the client computers cannot acquire IP address from this DHCP server.

This happens after you installed WDS on a DHCP server.



Cause
Windows Deployment Services attempts to listen on UDP port 67 for incoming DHCP Discover packets in order to PXE-boot clients. The same port is also used by the DHCP server.

The default configuration of Windows Deployment Services assumes that the Microsoft DHCP server and Windows Deployment Services server are on separate physical computers. When DHCP and Windows Deployment Services exist on the same computer, DHCP must inform the client computer that there is a PXE server listening on the network by including DHCP option tag 60 in the DHCP Offer packet.



Resolution
In the Windows Deployment Services snap-in:

1. On the Start menu, click Administrative Tools, and click Windows Deployment Services.

2. Click to expand the Servers list.

3. Right-click the server and click Properties.

4. On the Server Properties page, click the DHCP tab.

5. On the DHCP Options page, click to enable these options:

Do not listen on port 67

Configure DHCP Option 60 to 'PXEClient'

6. Click OK.

Note: To perform the actions above, you must be a member of the Account Operators group, Domain Admins group, or you must have been delegated the appropriate authority.
