Can't redeploy systems

Question

Have SCCM 2103. And (most probably since the SCCM Upgrade), we are unable to redeploy systems.

• The existing System is deleted in SCCM, as well as in AD
• The MAC address of the NIC is listened in the Hierarchy settings of the site (Duplicate Hardware identifiers)
• The TS is deployed to "all unknown computers to "only media and PXE" and with the option "always rerun program"
• Have executed "clear required pxe deployments" on the "all unknown computers" collection. Don't know what this is doing. But the TS deployment is not deleted, and the problem is not solved with that.

When PXE booting the client, we get "PXE-E16 - no valid offer received". Ans SMSPXE.LOG has the following entry:

Client Boot TS reply: <ClientIDReply><Identification Unknown="0" DuplicateSMBIOS="0" DuplicateMACAddress="0" ItemKey="2046820353" ServerName=""><Machine><ClientID/><NetbiosName/></Machine></Identification><TSInfo DeploymentID="SLA20052" PkgID="SLA000C4" BootImageID="SLA0005B" Architecture="9" Required="1" AlreadyRun="1" ForPXE="1" Disabled="0" PackageAvailable="1" FutureAvailability="0" Expired="0" UEFIArchitectureMismatch="0" ArchitectureMismatch="0"/></ClientIDReply>

"Already Run="1"" will be our problem. But have no idea where SCCM is getting this information, because the previousely deployed device is deleted in SCCM.

Thank you in advance for any advice

Hi @Franz Schenk ,

Thanks for posting in Microsoft Q&A forum.

We could check two options first:

1. Have you distribute both x86 and x64 boot image. It will not work properly if they are not both available.
2. Confirm that DHCP is configured correctly, or it may provide a wrong gateway for the device.

If there is no problem with the above checks, we could try the following solutions:

1. Verify IP Helpers
   If the DHCP server or WDS/PXE-enabled DP is not in the same subnet or VLAN as the client computer, they will not see or hear the PXE request broadcast from the client. Therefore, the server will not respond to PXE requests.
   For the detailed steps, please refer to this article:
   https://learn.microsoft.com/en-us/troubleshoot/mem/configmgr/troubleshoot-pxe-boot-issues#solution-1-verify-ip-helpers
   2） Reinstall PXE
   In many cases, errors during installation or configuration are the cause by PXE boot problems and reinstalling PXE may be the most effective and least time-consuming solution.
   To do it, please follow the steps in below link:
   https://learn.microsoft.com/en-us/troubleshoot/mem/configmgr/troubleshoot-pxe-boot-issues#solution-2-reinstall-pxe-use-only-if-solution-1-didnt-resolve-the-issue

Hope the information can help you.

Answer 2

Hi,

Thanks for your feedback, I noticed that there was an error "PXE-E16 - no valid offer received" so that I inferred from the beginning that it might be a PXE problem.

To clear the flag AlreadyRun="1", we could right-click the device object and choose Clear Required PXE Deployments.

Or do it on the collection the device object is in.
