Error saving on setup.aspx

When trying to press Save on setup.apx, I keep getting this error:

I followed this guide by nickbro: http://www.edugeek.net/forums/home-access-plus/116602-errors-saving-when-setup-aspx.html#post998077 but I can't seem to find the IIS AppPool\HAP user!

Error 0x80005000 is a generic Windows AD issue, restart the server should clear it
