Encountering errors while updating your SharePoint or WSS 3.0 ?

Whenever the installation of a service pack or hotfix results in erros try to do the following steps:

• restart your IIS
• restart your sharepoint timer service
• get to the command prompt and do
  • STSADM -o upgrade -inplace -forceupgrade -url [1] http://appadress
  • repeat for all your web applications including central administration, SSP, MySites and whatever else you’ve got
  • ignore any error messages at the command prompt
• restart your IIS and timer service once again
• run psconfig -cmd upgrade -inplace b2b -wait -force
  • if this ends up in errors again then
    • run the sharepoint configuration wizzard from your start menu
