Problem

When i clicked on the properties of the Database, I got this error on 2 of my Microsoft SQL Server 2005 databases.

TITLE: Microsoft SQL Server Management Studio

Cannot show requested dialog.

ADDITIONAL INFORMATION:

Cannot show requested dialog. (SqlMgmt)

Property Owner is not available for Database '[myDatabaseName]'. This property may not exist for this object, or may not be retrievable due to insufficient access rights.  (Microsoft.SqlServer.Smo)

For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&ProdVer=9.00.3042.00&EvtSrc=Microsoft.SqlServer.Management.Smo.ExceptionTemplates.PropertyCannotBeRetrievedExceptionText&EvtID=Owner&LinkId=20476

Cause

I have restored this databases in the past from other server's backup, and my original login is apparerently not available on target server.

Solution

You can fix it with 'sp_changedbowner sa'.

update:
I removed '2005' the subject of this post because you can have this error message on the Newer SQL Server 2008 also.

update 2:
The syntax to use in SQL Server Management Studio is:

use myDBName
EXEC sp_changedbowner 'sa'
