Unlike on the Mac, the FileMaker Server installation process does not create a local FMS Admin Group on the Windows Machine. So if you want to make use of this feature, you'll have to create the group manually. So let's go ahead and do that. Let's go over to our Windows machine and access the local accounts and your best way to do that is right click on My Computer and choose Manage, which will bring up this window and from here you can have access to local users and the local groups. As you can see, there's no FMS Admin Group amongst the groups that are installed on the machine, so let's go ahead and create one. And we'll add my domain accounts to that. Now, my domain account is now a member of the local FMS Admin Group on the FileMaker Server machine. So now let's go back to our Mac machine and see if we can log in to the FileMaker Server running on that machine with my Windows domain accounts. And as you can see, we can have access to the Admin Console. This works, of course, because we've already enabled allow members of the FMS Admin Group to log in for this particular Windows FileMaker Server. A special case for logging into the Admin Console is SSO, or Single Sign-On. Single-Sign-On used to work with FileMaker Server 7 and 8 for an administrator to log into the Admin Console, but it doesn't work anymore in FileMaker Server 9 and 10. Single Sign-On used to work in a very specific scenario where you had a Windows workstation that belong to an active directory domain with the administrator logged into that machine with his domain accounts. That domain account had to belong to the FMS Admin Group. Now, the Windows FileMaker Server also had to belong to the same active directory domain. Now, back in FileMaker Server 7 and 8 when the administrator launched the Admin Console, he would be given access to that Admin Console without having to provide his credentials. Like we said, that doesn't work any more in FileMaker Server 9 and 10, even though the specific Single Sign-On scenario would be valid. There is a separate movie in this tutorial about Single Sign-On. If you are using external authentication with a domain, either Windows Active Directory or Mac Open Directory, then you should create the FMS Admin Group on the domain controller and not locally on the FileMaker Server. External authentication and Single Sign-On are explained in greater detail later on in their movies. None of the changes that you make here require that you restart FileMaker Server except, that is, if you enable Access Restrictions. Access Restrictions are only applied and take effect at the next FileMaker Server restart.
