Our MP Cert expired. I have replaced it but our pxe boots are now receiving the following errors and never seems to get a DHCP IP address.
In SSL, but with no client cert.
reply has no message header marker
PXE: F8:75:A4:6B:05:80: Unsuccessful client info request. 0x80004005.
PXE::MP::IsKnownMachine failed; 0x80070490
I have reinstalled the MP and all shows good.
Any help is appreciated.
Seeing this in the MPControl Log but that cert is not being used MP has rejected the request because CD(SMSID = d249484c-6fc9-438b-be4d-bfdecf825aad) certificate has expired.
Solved issue was DP Cert had expired also.
