| The wait type PREEMPTIVE_OS_NETVALIDATEPASSWOR is ranked #73 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. The SQL Server PREEMPTIVE_OS_NETVALIDATEPASSWOR wait type is a type of wait that occurs when a session is waiting for the operating system to validate a password. This type of wait is typically associated with network authentication operations in SQL Server, such as logging in to a database using a SQL Server login or connecting to a remote server using a linked server. When a session is waiting on the PREEMPTIVE_OS_NETVALIDATEPASSWOR wait type, it means that it is unable to proceed with its current operation until the operating system has validated the password. This can cause delays and slow down the overall performance of the SQL Server instance. To troubleshoot and resolve issues related to the PREEMPTIVE_OS_NETVALIDATEPASSWOR wait type, it is important to first determine what operation is causing the wait and then investigate why that operation is taking a long time to complete. This may involve looking at the queries or processes that are executing the network authentication operation, as well as any other operations that are running concurrently on the SQL Server instance. In some cases, it may be necessary to optimize the queries or processes that are causing the PREEMPTIVE_OS_NETVALIDATEPASSWOR waits, or to adjust the workload on the SQL Server instance to reduce the occurrence of this wait type. It may also be necessary to adjust the settings of the network authentication operation to improve its performance and reduce the need for password validation. Overall, the PREEMPTIVE_OS_NETVALIDATEPASSWOR wait type can be a useful indicator of potential performance issues related to network authentication in SQL Server, and can help DBAs and developers identify and resolve those issues to improve the performance of their databases.
