SharePoint Event Log Error: Windows NT user or group 'DOMAIN\Administrator' not found. Check the name again.

So your SharePoint install seemed to work but in the event log you are getting messages like this:

A runtime exception was detected. Details follow.
Message: Windows NT user
or group 'DOMAIN\Administrator' not found. Check the name again.
Techinal Details:
System.Data.SqlClient.SqlException: Windows NT user or group

I searched for hours for a solution and found lots of posts that were not clear on why. Here are the two reasons I found for it:

  1. The user mentioned in the error does not have access to SQL Server
    CONFIRMATION STEPS: To determine this outside SharePoint simply go to Control Panel and create an ODBC Connection to the database and click test connection. If it fails then you hypothesis is right. If not try the second reason.

  2. The user mentioned in the error does not have write access to SQL Server
    CONFIRMATION STEPS: You can either drop a simple app that connects to the database on the server or you could look at the security settings on the sql server in question and see if that user has write permission
  3. I found an article on another reason for the error. If you are running SQL Server 2005 on a Windows 2000 box. Here is the article:

The thing to note here is that there may be more than one SharePoint database. You may think its failing on the content database connection but it could be on one of the other databases or if its a farm you may not have configured it on one of the farm databases.

Another thing to try if the above do not work or you are not sure what its trying to connect to is to look at the ULS log. You can find this by looking in:

\program files\commonfiles\microsoft shared\web server extensions\12\logs\{Machinename -timestamp}

If you have any more info on this error or other tips, tricks, resources please email them to and we will post them.

Securing SharePoint

I found a really good article on SharePoint Security. It summarizes the concepts quite well.

Find the real article at:

Here is an even more brief summary:

One thing to remember about SharePoint is that it is built on Asp.Net which is built on IIS.Realizing this you will realize that SharePoint 2007 "inherits" a lot authentication providers from Windows and IIS

Internet Information Server:

  • Basic
  • Digest
  • Certficates
  • NTLM
  • Kerberos

ASP.NET adds

  • LDAP
  • SQL Server
  • Active Directory
  • as well as quite a bit of extensibility.

I found an example of using a sharepoint list as an authentication provider at:

Forms-based authentication

HOWTO: Configuring a Office SharePoint Server 2007 Publishing Site with Dual Authentication Providers and Anonymous Access

Office SharePoint Server 2007 - Forms Based Authentication (FBA) Walk-through - Part 1

SharePoint Tutorials

Developing for SharePoint seems like such a large topic that its hard to know where to begin.
This topic will become a living document as we place links here to various topics and tutorials to help us all learn sharepoint:

  1. WebParts - These elements are the foundation of SharePoint so it is best if we learn how they work. This tutorial will walk you through using an existing webpart and creating a custom webpart.

If you have a suggestion for a tutorial or topic that would be the logical next step in our learning curve, please email Susan Fischer at and she will post them here.

SharePoint developer explorer on Visual Studio 2008

I found the work around to get the sharepoint developer explorer to work with visual studio 2008.

If you come across any tips like this please send them to me at and I will post them here.

WSPBuilder - What is your experience? Do you have any alternative?

When it comes to building manifest files and deploying the sharepoint webparts, I am still a newbie. I came across this tool and it seems to work. I am just wondering what your experience is with this tool and if you are aware of any other tools that would be useful when working with SharePoint.

If you come across any tooks please email them to me at and we will post them here.
