WDS Client error - An error occured while communicating with the WDS server.

Hi all,

I am setting up serveral Windows 2003 server using WDS. Most of the time it works flawlessly, but every once in a while I get this error message from the WDS Client:

"WdsClient: An error occured while communicating with the Windows Deployment Services server. Please check to ensure that the server is operational and that the necessary ports are open on the server's firewall. Server name [THENAME.thedomain], Server IP Address [192.168.0.1]"

This error appears at random, and it is strange, because at the same time 2 other blade servers on the same chasis were being deployed using the same technique. Also, the machine already booted from the network, and downloaded the WinPE image with the WDSClient - so the network conectivity does work.

Any pointers on what may be causing this error?

Thanks
