This is actually a problem with the Windows upgrade, but nonetheless the problem manifested itself while trying to install the sharepoint central database.
I had a development computer that was running Windows 2000 Server. I wanted to run SharePoint and use Visual Studio.Net 2003 to create some web parts. However, to do so, I had to upgrade to Windows 2003 Server. Normally I don't upgrade, since problems occur. However, I had heard some good things with the upgrade wizard. Note to self: never believe them. The upgrade itself went smoothly, however, I started having problems once I tried installing SharePoint.
The installation itself was smooth, but once I had to configure/create the central database, I started having problems. I'd fill out all the information, but every time I'd click submit I would be forwarded to a generic error message screen. I then tried creating the DB from the command line, by running: “stsadm -o setconfigdb -databaseserver [name] -databasename [db name]” Then I got a decent error: GetTextExtentPointI could not be located in msdart.dll. I found some good information here, and it fixed my problem for now. Basically, you need to copy over the oledb32.dll from another server that got a fresh install of Windows Server 2003 to the upgrade server.
I hope that helps someone else out.
