The prelogin packet used to open the connection is structurally invalid; the connection has been closed. Please contact the vendor of the client library.
We get quite a few of these errors.
Per microsoft...
The Max token size is already set to 65535 on the server but still these errors show up.They are benign by nature but how can we get rid of these errors.
Thanks

did you also read the "For additional details about the Kerberos and MaxTokenSize, see KB327825" link? ( https://learn.microsoft.com/en-US/troubleshoot/windows-server/windows-security/kerberos-authentication-problems-if-user-belongs-to-groups )

Yes I did. Thats a whole lot of edits everywhere.
The client computer that is running Internet Explorer---there could be 100's/1000's of these within a domain ...
The web server running that is running IIS
The SQL Server client computer
The SQL Server database computer
No interim solution ?

How do you know the error is benign? Do you know for sure that it is associated with something legitimate?
This could be something attacking your SQL server. Or it could be a penetration test of some sort.

Is there a workaround this issue instead of the below suggestion .
We have 1000's of systems in our domain.
