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.

Good call.  Just checked the vlan config and am focused on the mtu setting.  1500 bytes is the default if I'm reading this correctly.  WDS shows a maximum value way lower than that so I'll change it on the server to match that value.  What would the impact be if I changed that value (increased it) on the switch?
You can try that, but I would set the value based on your WDS documentation. It will just allow you to transfer more data per frame.
raised it to 1500 on the server and no change.  still getting the timeout/network error.
Are you positive the source pc is actually connecting to the WDS server?
It's seeing the Boot Image options available from the WDS server.  Once I select that on the source pc, it shows that it is pulling the related files from the WDS server for the WDS Imaging Wizard to run.
However once I enter in the server name for where the image should be stored, I get a network error.

At what point is the above. This sound like it was the very first step.

So based on your previous comment:

it shows that it is pulling the related files from the WDS server for the WDS Imaging Wizard to run.

Are you saying the process or file transfer starts then times out?
You mind sharing the switch config?
I ended up making the image and saving it locally to the source pc.  From there, I used a different boot image so the source (now target) pc could select the new image.  I was able to select the image and received the prompt for my domain credentials.  After that, the image pulled down.  The issue has to be with the capture image (boot image) [software] and not a hardware issue [cisco switch].

Going to close this out unless you can think of anything different.
I'll check for the switch config and upload it if it appears to be a network/switch issue.
Yes, I was pretty sure it wasn't the switch from my first comment. Seeing there was no filtering or firewall between the vlans.
Agreed but had to verify there wasn't anything in the config that I was overlooking.  The whole tunnel vision thing.
Thank you for your time and patience with this.  Much appreciated!
