SQL4-00-039100 - The SQL Server Browser service must be disabled if its use is not necessary..

Information

The SQL Server Browser simplifies the administration of SQL Server, particularly when multiple instances of SQL Server coexist on the same computer. It avoids the need to hard-assign port numbers to the instances and to set and maintain those port numbers in client systems. It enables administrators and authorized users to discover database management system instances, and the databases they support, over the network.

This convenience also presents the possibility of unauthorized individuals gaining knowledge of the available SQL Server resources. Therefore, it is necessary to consider whether the SQL Server Browser is needed. Typically, if only a single instance is installed, using the default name (MSSQLSERVER) and port assignment (1433), the Browser is not adding any value. The more complex the installation, the more likely SQL Server Browser is to be helpful.

This requirement is not intended to prohibit use of the Browser service in any circumstances; rather, it calls for administrators and management to consider whether the benefits of its use outweigh the potential negative consequences.

Solution

If SQL Server Browser is needed, document the justification and obtain the appropriate approvals.

Where SQL Server Browser is judged unnecessary, in the Services tool, double-click on 'SQL Server Browser' to open its 'Properties' dialog.

Set Startup Type to 'Disabled'.

If Service Status is 'Running', click on 'Stop'.

Click on 'OK'.
