I have a SBS 2011 with a issue with SharePoint and spfarm. During the maintenance process that SharePoint runs to change passwords it doesn't update the Services that spfarm is associated with. This leads to resetting the password in AD and running the following commands in SharePoint Shell:
Set-SPManagedAccount-UseExistingPassword-Identity "$env:userdomain\spfarm"
Repair-SPManagedAccountDeployment
iisreset/noforce
But this is only possible if the run once jobs have been removed that previously failed. If that hasn't been done before hand then I have to run the following:
STSADM -o updatefarmcredentials-userlogindomain.local\spfarm-password password-local
Any help would be greatly appreciated.
