PREEMPTIVE_OS_AUTHZINITIALIZECON SQL Server Wait Type

Wait Type PREEMPTIVE_OS_AUTHZINITIALIZECON

The wait type PREEMPTIVE_OS_AUTHZINITIALIZECON is ranked #37 by Stedman Solutions and Database Health Monitor.

Wait statistics, in the context of SQL Server, refer to the amount of time that a query spends waiting to access data in the database. When a client application requests data from the database, the request is placed in a queue and the client application must wait for its turn to access the data. The time that the query spends waiting is called a "wait" and is tracked by SQL Server. This information can be used to identify potential performance bottlenecks and optimize the performance of the database. Wait statistics are commonly used by database administrators to diagnose and troubleshoot performance issues in SQL Server.


One of the features of SQL Server is the ability to use Windows authentication to authenticate users and control access to the database.

One of the common wait types that can occur in SQL Server is the PREEMPTIVE_OS_AUTHZINITIALIZECON wait type. This wait type indicates that a task is waiting for the completion of an authorization initialization operation on the operating system.

Windows authentication is a common method of authenticating users in SQL Server. When a user attempts to access the database, SQL Server uses the operating system to verify the users credentials and determine whether they have the necessary permissions to access the database.

The PREEMPTIVE_OS_AUTHZINITIALIZECON wait type occurs when a task is waiting for the completion of an authorization initialization operation on the operating system. This wait type is a normal and expected part of the operation of SQL Server when using Windows authentication, and is typically not something that requires action.

However, if you are experiencing a high volume of PREEMPTIVE_OS_AUTHZINITIALIZECON waits, it could be an indication that there is a problem with the authentication process on your SQL Server. For example, the operating system may be experiencing delays in authenticating users, or there may be issues with the user credentials or permissions. In these cases, it may be necessary to troubleshoot the authentication process in order to reduce the number of PREEMPTIVE_OS_AUTHZINITIALIZECON waits.

Overall, the PREEMPTIVE_OS_AUTHZINITIALIZECON wait type is a normal and expected part of the operation of SQL Server when using Windows authentication. While it is typically not something that requires action, it is important to monitor for high volumes of these waits, as they can indicate potential issues with the authentication process on your SQL Serve
