We are a fairly small shop < 200 users that is setting up Sharepoint 2013 for the first time all on one server. It was originally installed with a domain admin account. The same account we log onto the server with. I believe this is incorrect as I have seen posts about separate accounts.
What type of account do I need for Sharepoint 2013?
How and where do I switch the account used without doing a re install?
Details would be appreciated as we are new to sharepoint.
