SYMPTOMS
Consider the following scenario. You install Microsoft SQL Server 2005 Community Technology Preview (CTP) on a computer that is running Microsoft Windows Server 2003. Then, you try to back up data from a volume by using the Volume Shadow Copy Service (VSS). Under these conditions, you may receive the following error message:

Error returned while the creating volume shadow copy: 80042301

Additionally, you may find that the VSS has stopped and that you cannot restart the service.

This issue only occurs in versions of Microsoft SQL Server 2005 CTP earlier than build 09.00.1178.01.

Note If you are currently experiencing this issue, and you are running a version of SQL Server 2005 CTP that is earlier than build 09.00.1178.01, you cannot resolve this issue by applying the latest build of SQL Server 2005 CTP.

If you have not installed any version of SQL Server 2005 CTP, and you install build 09.00.1178.01 or a later version of SQL Server 2005 CTP, you will not experience this issue.



CAUSE
This issue occurs because the Setup program for SQL Server 2005 CTP leaves an invalid registry entry under the follow subkey:

The invalid registry entry has no value.



WORKAROUND
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

To work around this issue, follow these steps:  Start Registry Editor. Locate and then click the following key in the registry:

 

 Right-click the VssAccessControl key, and then click Delete. Quit Registry Editor.

Note After you delete the registry key, you must make sure that the startup account of the SQL Writer Service is running as an Administrators account or as a Backup Operators account.
