From: MartinSkau on
I tried to install MS CRM 3.0 (small business edition) on a smb 2003
premium, on which I had installed SQL Server 2005. There were too many
issues - in short I could not get CRM to install correctly. So I
decided to roll back to SQL Server 2000. By mistake (it now turns out).
I tried to remove the IIS reporting service component of SQL server
2005 (by simply deleting the site). After that the Reporting Service
component of SQL 2005 will not uninstall. I tried to recreate the
Reporting Services IIS web via the tool included with the SQL server
installation (now I don't remember the name of it, and it has been
uninstalled) - and it seemed to have been re-created correctly. But I
still can't uninstall the Reporting Services. Trying to
re-install/repair the installation does not help either. I get the
following error:

"Microsoft SQL Server 2005 Setup"
The Setup failed to read the IISMimeMap table. The error code is
-2147024893

After pressing OK the Reporting Services uninstall will roll back.

How can I uninstall the component, hence uninstall the complete SQL
Server 2005?

Eventually I can do a complete server re-installation. The system is
running on a virtual server, and is only a testing system with no vital
data or processes. For that reason there is no backkup.
