Network Considerations and User Accounts
MultiPoint Server can be deployed in a variety of network environments, and it can support local user accounts and domain user accounts. Generally, MultiPoint Server user accounts will be managed in one of the following network environments:
A single computer running MultiPoint Server with a local user accounts
Multiple computers running MultiPoint Server, each with a local user account
Multiple computers running MultiPoint Server and that are using domain user accounts (this scenario is only available when using Windows MultiPoint Server 2011 Premium
By definition, local user accounts can only be accessed from the computer on which they were created. Local user accounts are user accounts that are created on a specific computer that is running MultiPoint Server. In contrast, domain user accounts are user accounts that reside on a domain controller, and they can be accessed from any computer that is connected to the domain. When you are deciding which type of network environment to use, consider the following:
Will resources be shared among servers?
Will users be switching between servers?
Will users access database servers that require authentication?
Will users access internal web servers that require authentication?
Is there an existing Active Directory domain infrastructure in place?
Who will be using the MultiPoint Manager console to manage user desktops, view thumbnails, add users, limit websites, and so on? Will this person be managing more than one server? This person must have administrative privileges on the servers.
The following sections address user account management in these networking environments.
Single MultiPoint Server with local user accounts
In environments with a single computer that is running MultiPoint Server, there is no requirement to have a network. However, to take advantage of Internet resources, the networking requirements may be as basic as a router and a connection to an Internet service provider (ISP). Network connections that are associated with a network adapter on MultiPoint Server are configured, by default, to obtain an IP address and DNS server address automatically through DHCP. Internet routers are typically configured as DHCP servers, and they provide private IP addresses to computers that connect to them on the internal network. Therefore, a single computer running MultiPoint Server may be able to connect to the internal interface of the router, obtain automatic IP information, and connect to the Internet without significant effort or configuration by an administrator.
A common way to manage users in this kind of environment is to create a local user account for each person who will access the system. Anyone who has a local user account on that computer can log on to MultiPoint Server from any station that is associated with the system. Local user accounts can be created and managed from MultiPoint Manager.
Multiple MultiPoint Server systems with local user accounts
Given that local user accounts are only accessible from the computer on which they were created, when you deploy multiple MultiPoint Server systems in an environment, you can manage local user accounts in one of two ways:
You can create user accounts for specific individuals on specific computers running MultiPoint Server.
You can use MultiPoint Manager to create accounts for every user on every computer running MultiPoint Server.
For example, if you plan to assign users to a specific computer running MultiPoint Server, you might create four local user accounts on Computer A (user01, user02, user03, and user04) and four local user accounts on Computer B (user05, user06, user07, and user08). In this scenario, users 01-04 can log on to Computer A from any station that is connected to it; however, they cannot log on to Computer B. The same is true for users 05-08, who would be able to log on only to Computer B, but not to Computer A. Depending on the specific deployment environment, this can be acceptable or even desirable.
However, if every user must be able to log on to any of the computers running MultiPoint Server, a local user account must be created for each user on each computer that is running MultiPoint Server. Choosing to manage users in this manner introduces certain complexities. For example, if user01 logs on to Computer A on Monday and saves a file in the Documents folder, and then the user logs on to Computer B on Tuesday, the file that was saved in the Documents folder on Computer A will not be accessible on Computer B.
Additionally, if a user has accounts on Computer A and Computer B, there is no way to automatically synchronize the passwords for the accounts. This can result in users having difficulty logging on should the account password be changed on one computer, but not the other. You can simplify user account management in this kind of network environment by assigning each user to a single computer that is running MultiPoint Server. This way, the user can log on to any of the stations that are associated with that computer and access the appropriate files.
Multiple MultiPoint Server systems with domain accounts
Domain environments are common in large network environments that include multiple servers. For example, you might join one or more computers running the Windows MultiPoint Server 2011 Premium to a domain, and then use Microsoft Active Directory to manage user accounts that can be accessed from any computer in the domain. This allows for individual domain user accounts to be created and accessed from any station in any MultiPoint Server system that is joined to the domain.
Only Windows MultiPoint Server 2011 Premium supports joining a domain; computers running Windows MultiPoint Server 2011 Standard cannot join a domain.
When you deploy MultiPoint Server in a domain environment, there are several factors to consider:
If domain accounts are used, they cannot be managed from MultiPoint Manager.
By default, MultiPoint Server is configured to give each user permission to log on to only one station at a time. If you decide to allow users to log on to multiple stations at the same time using a single account, you can use the Edit Server Settings option in MultiPoint Manager.
The location of domain controllers may affect the speed and reliability with which users will be able to authenticate with the domain and locate resources.
Single user account for multiple stations
New to Windows MultiPoint Server 2011 is the ability to log on to multiple stations on the same computer simultaneously using a single user account. This feature is useful in environments where users are not given unique user names, and where using a single user account can simplify the management of the MultiPoint Server system.
