My lab VM with Win2003 x64, BizTalk 2006 R2, SharePoint 2007 and SQL Server 2005 SP-2 runs very nice, but I forgot to upgrade SharePoint to the new SP-1 version. I would like to mention that this VM was installed with all the default and typical settings selected for all installed products.
The SP-1 for SharePoint 2007 requires WSS 3.0 to be upgraded to SP-1 first. But, this installation failed. The error was:
One or more configurations failed. Completed configuration settings will not be rolled back. Resolve the problem and run this configuration wizard again. System.InvalidOperationException. Cannot start service SPTimerV3.
The upgrade itself was successful, but the wizard failed to start the 'Windows SharePoint Services Timer' NT service. I opened up services.msc and tried to start it manually, but it also fails. The error in the Event Viewer is: The service did not start due to a logon failure.
Maybe this can be caused by the dcpromo-process this lab VM undergone. The server is now a Primary Domain Controller (and wasn't while SharePoint was initially installed).
Changing the 'Log on as' on the 'Log on' tab of the service to a valid account (and password) solved this problem. I started the service manually and pressed the Finish button of the configuration wizard.
Now the SharePoint SP-1 itself...
