Ever since changing to Windows 11 we have some workstations that now and then try to connect via smart card, but we don't use smart cards.
The event occurs with the computer's account, not a user's account, which is also interesting.

Pre Auth Type: 16
Ticket Options:
0x40810010 - Forwardable, Renewable, Canonicalize,
Renewable-ok
1
Forwardable
(TGT only). Tells the ticket-granting service that it
can issue a new TGT—based on the presented TGT—with a different
network address based on the presented TGT.
8
Renewable
Used in combination with the End Time and Renew Till
fields to cause tickets with long life spans to be renewed at the KDC
periodically.
15
Name-canonicalize
To request referrals, the Kerberos client MUST
explicitly request the "canonicalize" KDC option for the AS-REQ or
TGS-REQ.
27
Renewable-ok
The RENEWABLE-OK option indicates that a renewable
ticket will be acceptable if a ticket with the requested life cannot
otherwise be provided, in which case a renewable ticket may be issued
with a renew-till equal to the requested end time. The value of the
renew-till field may still be limited by local limits, or limits
selected by the individual principal or server.
Failure Code:
0x10
KDC_ERR_PADATA_TYPE_NOSUPP
KDC has no support for PADATA type (pre-authentication data)
Smart card logon is being
attempted and the proper certificate cannot be located. This problem
can happen because the wrong certification authority (CA) is being
queried or the proper CA cannot be contacted in order to get Domain
Controller or Domain Controller Authentication certificates for the
domain controller. It can also happen when a domain controller doesn't
have a certificate installed for smart cards (Domain Controller or
Domain Controller Authentication templates).
Pre Auth Type:
16
PA-PK-AS-REQ
Request sent to KDC in Smart Card
authentication scenarios.
I would like to get it to stop, but I have been having difficulty nailing it down.
Wanted to see if anyone else has run into something similar and found a solution.
