I am in the middle of upgrading my Quickbooks 2005 Pro to Quickbooks 2010 Pro. After installing the server, transferring the company files and installing one client machine, I ran a test by attempting to connect to the newly converted company files on the server. I noticed at this time that the admin account in one of the comapny files was missing. Called quickbooks support and they told me it is virtually impossible to delete this account, even though I told them it appartently had been because it wasn't there. My other company files have an admin account that I can see. Anyway...does anyone know of a way to recover from this problem. Any help would be appreciated.
