SharePoint Services SharePoint Admin Console and companyweb are unavailable. In our case, this occurred after a windows update was installed but failed to complete.
Rerun the Sharepoint Products and Technologies Configuration Wizard (psconfig)
- Open services.msc and restart the Windows Internal Database service
- Run the following command from an elevated prompt:
C:Program FilesCommon FilesMicrosoft SharedWeb server extensions12BINpsconfig -cmd upgrade -inplace b2b -wait -force
- Verify that both the Admin Console and Companyweb are back up. If the Admin Console is up but companyweb is not, be sure to check the website bindings in IIS
