We have a 2010 SharePoint farm that we took over from staff that left. We are currently going through a compliance audit of SharePoint accounts that are in the local administrators group and the main question is, do these accounts still need to be in the administrators group or is it safe to remove them? Some of these accounts do show up in the Central Admin under Monitoring\configure managed accounts...however, they have no SP components listed with them....
ProdInstall - it's assumed this account was used as the primary SP installation account and it shows up in a few places in the registry but no services or IIS pools are bound to it and no components listed in Central Admin.
ProdSuperReader - no clue what this account is for and it shows no components in Central Admin nor does it have any services or app pools bound to it. Like the account above, it does have a few references in the registry or one or more farm machines.
Bottom line is it best practice or advisable to remove these accounts from the local administrators group on the farm machines? Yes I know testing would be a must be would like to hear from someone who has experience with this scenario. I am sure I'm not the only one who has a security group who tries to minimize accounts in the local admin group on production servers.
Thanks for any light you can shed on this!
