wds stops working on clients pxe-e32 tftp open timeout

[sted]

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.

2008r2 fix

run regedit

go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic es\WDSServer\Parameters

Right-click UdpPortPolicy, and then click Modify.
In the Value data box, type 0, and then click OK.
On the File menu, click Exit to exit Registry Editor.
Restart the Windows Deployment Services service.

2008 r1

Click Start Collapse this imageExpand this image, click Administrative Tools, and then click Windows Deployment Services. If there is no server that is listed under the Servers node, right-click the Servers node, and then click Add Server to add the local computer.
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

Thanks. This worked on 2008 R2. Is this a bug that Microsoft addresses in their KB?

We've had this issue intermittantly and we use to reinstall and WDS server role and it would fix the problem (probably just updates the reg key really). We originally searched for a proper solution (though half the time Microsoft's solutions are reinstall it) but the issue happened so rarely and we've been so busy that it didnt seem worth it at the time.

Thanks, Sted! That fixed my problem. It's always nice to Google a problem and end up back at good old Edugeek

Hi ,

I ran through this issue this morning. Didn't knew why that happened suddenly as everything was running smoothly and then I was annoyed as I didn't managed to get a single vm to boot on pxe. I have 2008 R1 running fine now by rising upd ports range.

You saved my day

Hi Sted,
Thank you for posting this fix, I am runnig SBS2008 with WDS & it worked for me also. It also happened after applying various Windows updates.
Thought I was going to have to recover my WDS from a backup. I used the 2008 R1 fix.
Thank you

Thanks. I had WDS working on a clean install of 08 R2 just for test purposes. I shut it off for the night, booted it in the morning, and ran in to the TFTP timeout error. Tried a few other things before this fixed it!

Thanks Sted, I was trying to set up a pxe boot inside VM Workstation and could not get my client machine to connect to the server (2008 R2).
This worked a treat - thanks for your help
