SCCM 2012 - WDS responding to PXE requests, not SCCM

Hi Guys,

I am stumped on an SCCM / WDS issue where when a client PXE boots, they are hitting WDS rather than SCCM. Since WDS isnt configured / initialized it has no boot images and as such you are presented with a message that says as much (not the no pxe boot found error).

If I add a boot image to WDS, it will load this image however this doesnt load the SCCM bits and ultimately the task sequence that has been advertised.

I have uninstalled and reinstalled WDS in a number of ways. The only thing I havent tried is removing the dist point as this is the only SCCM server and I am worried about losing any packages ect that have been created.

Not sure where to go from here as I cant find anything on Google for this.

Thanks
Chris

Hi

Have you checked your DHCP settings, specifically option 66 as well as maybe looking at if option 67 is set and pointing to the correct file location.

Hope this helps a bit

Thanks

Neither option is set as this is all in the same subnet.

This issue is still ongoing. I have configured both option 66 and option 67 in DHCP, removed and reinstalled WDS in multiple ways to try and get this to work properly but no joy.

I have removed and re-installed SCCM but issue still exists.

When PXE boots it trys to use: boot\x64\pxeboot.com
Rather than: SMSboot\...

Hi

The only other thing I can think of right now is that there might be some corruption in your .wim files, I would remove the boot images and re add them again and also maybe check that your AV is not to blame and stopping something somewhere on the server.

Is your option 67 something like this \smsboot\x64\pxeboot.com ?

Thanks

I uninstalled AV on the server to make sure that it wasn't the cause.
Option 67 is set to: SMSBoot\x86\wdsnbp.com

My understanding is that when SCCM installs WDS it should only have a few folders in RemoteInstall, and if "boot" exists it wont work. I cant delete this as it just gets recreated.

This all went wrong when someone thought that WDS wasnt configured and went and configured it (20+ installs ago)

Ok have you also maybe looked to see if there are any "unknown" computers in your "All Systems" collection ? if there are any delete them then maybe try again ?

My PXE boot server has the boot folder in it and all works perfectly.

What error are you getting ?

Thanks

There are what looks like 2 devices in All systems, but they cant be deleted:
"x64 Unknown Computer (x64 Unknown Computer" and "x86 Unknown Computer (x86 Unknown Computer".

Attached is the error I get on the PXE client.

That's not good :)

Maybe try go to PXE options on the DP and untick enable, wait a while for WDS to uninstall then go back and tick it again, once WDS is installed again then try boot again.

Also do you have both boot images distributed, x86 and x64 ?

thanks

Also maybe delete the "RemoteInstall" folder after un-ticking and removal if it doesn't remove it on its own

Resulted in a fresh install of Server 2012 and SCCM. I suspect that there is something in the registry that remembers that WDS was configured before and everytime SCCM installs it, it reverts to that state.
