The ConfigMgr Advanced Client rejected the site server signing certificate
Error messgae “The ConfigMgr Advanced Client rejected the site server signing certificate to a trust-related failure (0x800b0109)” is showing up on few clients which are failing to install the certificate from the enterprise root CA.
Solution :
Compare the following registry values between a working and a failing client. If the values are different, replace the values on the bad machine with those from the good machine and re-install the client:
X64 – HKLM\Software\WOW6432Node\Microsoft\CCM\Security
X86 – HKLM\Software\Microsoft\CCM\Security
Keys - AllowedRootCAHashCode, Signing Certificate.
This may be helpful as well: Renewing or Changing the Site Server Signing Certificate
