Hi, @Boopathi S
Thank you for posting in Microsoft Q&A forum.

Have we checked SMSPXE.log to see if there any error or any words like "device is not in the database"?
And is there anything special about this DP compared to others?
Did you configure the DHCP scope option 66 and 67?

For me a restart of the server got things working again.

Hello @AllenLiu-MSFT ,

There is no word like "device is not in the database" in SMSPXE.log. There is not difference like in other DP's.

User Device affinity is set as "Do not use user device affinity" in other DP's.
I set it to "Allow user device affinity with automatic approval" for this DP as it is "Waiting for approval"

Hi, @Boopathi S

Why do you set "Allow user device affinity with automatic approval" for this DP?
Have you enabled Automatically configure user device affinity from usage data in client setting?
Select True to let the site automatically create user device affinities. If you select False, you need to manually approve all user device affinity assignments.

We are also seeing this since we upgraded to 2107 with the latest KB installed.

The SMSPXE.log reports the following:

PXE::Settings::GetVariablesFile failed; 0x80004005
PXE::Settings::GetVariablesFile failed; 0x80004005
