Event -29

Hi Team,

Having warnings in our DC, as below. (We have win2k8 R2 servers and using AD CS for certificate services)

Event  -29
The Key Distribution Center (KDC) cannot find a suitable certificate to use for smart card logons, or the KDC certificate could not be verified. Smart card logon may not function correctly if this problem is not resolved. To correct this problem, either verify the existing KDC certificate using certutil.exe or enroll for a new KDC certificate.

Kindly help us to fix the issue

Thanks SUBBU.T
