Hello Shakoane,
Thanks for your posting on Q&A.
It seems that the issue is due to the duplicate SusClientId. Please open the CMD as an administrator and run the below commands one by one to delete the SusClientId. Then we could check whether the issue will be resolved or not.
net stop wuauserv
del /S /Q C:\Windows\SoftwareDistribution\*.*
RMDIR /S /Q C:\Windows\SoftwareDistribution\
reg.exe delete HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate /v PingID /f
reg.exe delete HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate /v AccountDomainSid /f
reg.exe delete HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate /v SusClientId /f
reg.exe delete HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate /v SusClientIDValidation /f
net start wuauserv
Then we could force the two Servers check for updates manually. Please wait for a while and the two servers should report to the WSUS server.
In addition, please run the Server Cleanup Wizard to clean up if you haven't maintenance the WSUS server for a long time.
Please keep us in touch if there are any updates of the case. Looking forward for your updates.
Have a great day.
Regards,
Rita
