  • Do you have DNS also installed?

  • yes, AD integrated forward lookup zone for the AD domain that the WDS machine is a domain controller for.... the AD domain is only for deployments, nothing else. In fact ADDS is only installed because, sadly, it is a requirement for WDS. I really wish it wasn't.

  • In Server08R2, you can use the PXE provider in the transport server role to remove the dependacy on AD. See http://technet.microsoft.com/en-us/library/dd348475(WS.10).aspx for more details.

    With DNS and WDS running on the same machine, you can randomly have issues when the DNS port range and the WDS port range overlap.  This is due to a security fix in DNS that causes the DNS process to bind to 2500 ports at once. Some of the known issues with this DNS fix are tracked here: http://support.microsoft.com/kb/953230.

  • Hi All - 

    I'm late to the party on this one.  But I recently built a WDS Server using images I created from deployment workbench.  I'm trying to get the PXE Boot option to work, but the farthest I get is that the client receives the IP, and then the TFTP Timeout error occurs.  I'm a rookie at using WDS.  What should I be checking as to the causes of the TFTP Timeout error I'm getting.  

    I'm not sure if I'm using the right Boot file.  I have option 66 enabled and 67 using the bootfile I think I should be using.  Anyway, any suggestions would help.  I've tried many of the steps here.  Also, if a moderator could point me to the right thread if this thread is closed.
