we have 3 servers dbsrv (sql server is running as network service) and srv1 and srv2.
One user (domain)\dbuser while trying to connect to dbsrv1, configuring odbc (create new odbc connection from admin tools) getting the error:
Login failed for user '(domain)\dbuser'. Reason: Token-based server access validation failed with an infrastructure error. Check for previous errors. [CLIENT: <srv1 IP address>]. This error i see in the dbsrv logs.
But, the same operation from srv2 does not generate the error (the same user, the same operation).
Now, Other user (domain)\dbuser1 can succesfull connect to dbsrv from srv1 and srv2 (the same operation: creating odbc connection).
any idea. it was working and one day it stops.
