Task configdb has failed with an unknown exception

This weekend I tried installing the SharePoint 2010 beta onto my Windows 7 laptop. After following all the steps mentioned in the MSDN article, I ran into an error.

Because I already had a SQL2008 installation, I didn’t go for the stand alone installation, but I chose a server farm setup. When running the config wizard for the first time; you need to specify the SQL server where your configuration database will reside. I chose my local installation and provided username / password. After that, the wizard would fail with the error ‘Specified value is not supported for the {0} parameter.’.

I tried again, but it would consequently fail. Then I took a better look at the actual error in the log file:

“Exception: System.ArgumentException: Specified value is not supported for the {0} parameter.
at Microsoft.SharePoint.Utilities.SPUserUtility.GetDomainControllerToSearch(SPWebApplication webApp, String domainName)
at Microsoft.SharePoint.Utilities.SPUtility.GetDomainAndPropColl(SPWebApplication webApplicaiton, String loginName, String[]& resolveUserAdProperties, SPActiveDirectoryDomain& gcPath, ResultPropertyCollection& propcol)
at Microsoft.SharePoint.Utilities.SPUtility.GetUserPropertiesFromAD(SPWebApplication webApplicaiton, String loginName, String[]& origUserAdProperties)
at Microsoft.SharePoint.Utilities.SPUtility.GetUserPropertyFromAD(SPWebApplication webApplicaiton, String loginName, String propertyName)…”

Ok, so it seems it needs the AD for something… Ah!… I used my AD account for access to SQL server. It seems the configurator needs some additional info from Active Directory. Since I was sitting at home without any connection to my work network (where the AD resides), the additional info couldn’t be retrieved. Once I tried the same steps whilst connected, everything worked fine.

As always; the error message couldn’t be more clear 😉
