BUG: SP1 Regression: Uninstalling SQL Server 2000 Does Not Remove the MSSQLServerADHelper Service (308853)


The information in this article applies to:

  • Microsoft SQL Server 2000 (all editions) SP1
This article was previously published under Q308853
BUG #: 355361 (SHILOH_BUGS)

SYMPTOMS

MSSQLServerADHelper is a service installed by the SQL Server Setup program that handles the Active Directory objects for all instances of the SQL Server relational database engine and all Analysis Manager applications that are running on the computer. There is only one MSSQLServerADHelper service on a computer for all of the instances of Microsoft SQL Server 2000.

On computers that are running SQL Server 2000 Service Pack 1 (SP1), uninstalling all the instances of Microsoft SQL Server 2000 does not remove the MSSQLServerADHelper service.

This problem does not occur on SQL Server 2000, but does occur with SQL Server 2000 Service Pack 1.

CAUSE

The problem occurs because the uninstall process fails to remove a registry key.

WORKAROUND

To work around this problem, delete the registry key that was not removed by the uninstall process.

Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs.
