Late last week, we inadvertanly changed the SharePoint farm account to another less privleaged account that was running other services. This account is a domain user and is not assigned any privileges to the local server administrator group. When using the Central Admin to change the service account back to the orginal setting, we get an error stating the object exists. When browsing in managed accounts, I noticed both the orginal farm account and the new less privileged account are both set as farm accounts. Being totally new to sharepoint, I am looking for the implications to this issue. Will this cause problems in the future? Is there a need to move the farm account back to the original user or do I just leave it alone?
