We have SBS2011. After a recent server reboot the Companyweb Sharepoint site was not working (HTTP Error 503: The service is unavailable.) and I noticed that services running as DOMAIN\spfarm had not started with a logon error, i.e.:
SharePoint 2010 Timer
SharePoint 2010 VSS Writer
So I changed the AD password for that account and updated the services - they now start. However, no change with the Sharepoint site, and the following errors in the System log, all from source WAS:
5021: The identity of application pool SharePoint Central Administration v4 is invalid.
5057: Application pool SharePoint Central Administration v4 has been disabled.
5059: Application pool SharePoint Central Administration v4 has been disabled.
Plus the same three errors for the "SBS Sharepoint AppPool".
I checked the membership of DOMAIN\spfarm, it is a member of IIS_IUSRS and IIS_WPG, as is DOMAIN\sbswebapp. Both groups have "Logon as a batch job" set in the Default Domain Controllers Group Policy.
I was able to fix the SharePoint Central Administration v4 errors by running the following command:
STSADM -o updatefarmcredentials -userlogin DOMAIN\spfarm -password [AD password]
So now I can run Central Administration, but still not the Sharepoint site.
What steps must I take next?
