wds stops working on clients pxe-e32 tftp open timeout
incase this happens to anyone else (just happened to me after installing an update on the server and a couple of clients i rebuilt wouldnt boot as they just hung waiting for a tftp offer)
has happened to me after a windows update on server 2008 r2 (aparantly happens on straight 2008 as well) basically its due to having dns server on the same machine as wds dns pinches the ports the tftp service needs. This can leed to pcs not booting at all just sitting there failing to tftp if their boot order has lan set higher than hdd.
go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic es\WDSServer\Parameters

In the navigation pane of the Windows Deployment Services MMC snap-in, expand the list of servers.
Right-click the server for Windows Deployment Services, and then click Properties.
Under Network, increase the UDP Port range. For example, if the current port range is 3,000 ports, increase the port range to 4,000 ports
