SOLVED PXE BOOT- PXE-E16 No vaild offer received

[V3TR4x]

Hello Everbody,
Short information about the system
I am using a Configuration Manager 2107 Version 5.00.9058.1000

I have one Primary Site, 7 secondary sites ( warehouses ) and about 24 Distribution Points in other countries.

In the LAN of the Primary Server I have a second Server ( Distribution Point ) on this Server I have the WDS Service installed.
I am using SSL in the whole network.

Now to my Problem:
since about one week I have the problem that the PXE BOOT isn't working anymore.
As I tried to look into the problem I checked the smspxe.log on the distribution Point. I couldn't found it anymore. I removed the PXE from the Distribution Point and reinstalledthe WDS Service again. Same Problem as before.

I checked the registry about the log path and couldn't find anything.

Does somebody has any idea about the problem, if not I will delete the whole Distribution Point Server and create a new one ( my last solution)

thanks for the help

with kind regards

Are you sure there is no SMSPXE.log ?. This seems more like a network issue to me. Was there any changes done to the network such as IP helpers etc ?.

Hi,
No, there where no changes in the network.

After hours of searching I found the smspxe.log.....



it looks like my certificate is the problem.
I didn't make any changes on it but I will look into it now.

Hello again,
I found the problem to this case.
the certificate has only SHA1 and I updated the SCCM to Version 2107.
After the update the Clients can't connect to the SCCM ( weak algorithm )

with kind regards
