To get PXE working on a server that is running both DHCP and WDS you need to enable option 66 and 67.
These settings will help your connecting clients to find the appropriate PXE server.

The setting is found in the DHCP configuration manager window (MMC).

Expand IPv4 and go to Server Options, right-click and select Configure Options.
Scroll down and select:

066 Boot Server Host Name
067 Bootfile Name

For option 066 write the IP of your WDS server. ( for example).
For option 067 write: \smsboot\x64\

Press OK and try booting the client.
