RTM versions were downloaded over the weekend and I'm setting them up now.

Weird error encountered with SQL Server 2005 setup; On a WinXP SP2, I'm getting the following message:

"SQL Server Setup failed to modify security permissions on WMI namespace \\.\root\Microsoft\SqlServer\ServerEvents\DEV2005. To proceed, verify that the account and domain running SQL Server Setup exist, that the account running SQL Server Setup has administrator privileges, and that the WMI namespace  exists on the destination drive."

I googled the first line and found no results, so I figured I'd post this in case anyone else runs across this error.  Further googling led me to an MSDN article regarding Setting Namespace Security.  I followed the instructions but wasn't able to find the namespace \\.\root\Microsoft\SqlServer\ServerEvents\DEV2005.  Note that I'm installing 2005 as a named instance ("DEV2005" being the name of my instance), so this may not be an issue with default instances.

My current action is to abort the install and try again...I'll update if there are other developments.

Update: I switched to the default, non-named instance and it seems to work fine...however, I get an error when the installer tries to install the sample databases 'doh!  It says that my account is not an admin account, even though it is...
