Ok the last days I got some error messages while installing SharePoint 2007 SP2. The error messages didn’t occur because of SP2… the problem was my development environment so it was easy to find a solution.

Failed to detect if this server is joined to a server farm.

The first error message was

“Failed to detect if this server is joined to a server farm.  Possible reasons for this failure could be that you no longer have the appropriate permissions to the server farm, the database server hosting the server farm is unresponsive, the configuration database is inaccessible or this server has been removed from the server farm.  To diagnose this problem further, review the extended error information located at {0}.  If this problem persists, choose to disconnect from the server farm.  After disconnecting, run the wizard again to create or connect to an existing server farm.”

The problem was related to my SQL Server service which wasn’t running. So after restarting the service the installation of SharePoint 2007 SP2 was no problem.

Failed to register SharePoint services.

After installation I was running the SharePoint Products and Technologies Configuration Wizard which stopped with the following error message:

“Failed to register SharePoint services. An exception of type System.Security.SecurityException was thrown.  Additional exception information: Access denied. Completed configuration settings will not be rolled back.  Resolve the problem and run this configuration wizard again.  The following contains detailed information about the failure:”

It was a long time ago when I received this error message and I remembered to restart the wizard which was successful the second time.

Conclusion

The problems may occur in scenarios where SP2 is not involved since they were related to my environment. ;) I hope this helps if you are having problems installing SharePoint 2007 SP2 or something else.
