We have a Sharepoint 2010 server which has been running just fine until we changed our domain administrator account name from Administrator to another name. Now I am able to log into sharepoint and access and create/modify tasks, but search does not work and I am unable to use the Central Administration page to change the sharepoint account settings.
If I use Sharepoint Central Administration and go to Security > Managed Accounts, I see our new administrator account listed (it is the only thing listed) but if I click "Edit" and try to save the settings or even create a new managed account, I receive this error:
"The specified user or domain group was not found."
I am also receiving this error when I attempt to search within sharepoint:
"Internal server error exception:
Troubleshoot issues with Microsoft SharePoint Foundation.
Correlation ID: e1623651-8a30-48f6-899e-494c7e10a860"
If I try to access the Search Application through Central Administration, I receive the
"The specified user or domain group was not found" error message.
Can I use the SPConfig tool to make sure everything is using the new account name properly?
