SharePoint: Class not registered & File System Permissions

Posted by MLK under SharePoint Services

Description/Problem:
I had several issues with SharePoint Service during implementation on Windows 2003 server member and also domain controller. The 1st issue was related to unable start-up of SharePoint Service. The web interface present each time the error message: “Start action dailed. Additional information: Class not registered”. The 2nd issue was also interesting for me because the configuration wizard for new installation of SharePoint Service failed on Step 5 of Step 10.

Solution:

• Apply special file system permissions (add to existing)
• System Disk (C:)
  • Local Service (Read & Execute List Folder Contents Read)
  • Network Service (Modify Read & Execute List Folder Contents Read Write)
  • WSS_Admin_WPG (Full Control)
• System Folder (%systemroot%\Temp)
  • Network Service (Full Control)
  • WSS_Admin_WPG (Full Control)
  • WSS_WPG (Read & Execute List Folder Contents Read)
• Restart SharePoint Services
