Cisco vlan preventing WDS image capture

Now that I created my Win7 Enterprise image, I've ran the sysprep util and the Windows 2008 R2 server that has WDS configured is ready for the image.  I have done this process several times before without a problem but for whatever reason, when I boot the source pc up using network boot, the source pc gets the WDS splash screen.  So I know the source pc is communicating to the WDS server.  However once I enter in the server name for where the image should be stored, I get a network error.

In the error log, I see the connection between source pc and WDS server timed out.  I'm running a constant ping to the source pc so I know it's still communicating but further research showed there may be something with our Cisco 2960 and/or possible vlan configuration.  Where would I check for a setting that would drop the traffic between the two?  Note: all of the network traffic is on the same lan and doesn't go through any routers, just the Cisco switches.

Thanks in advance for your time and assistance.  If you need additional information or for me to clarify anything, please let me know.
