This article describes issues regarding the use of BackOffice Server (BOS) 2000 or Small Business Server (SBS) 2000 with Terminal Services running in Application Sharing mode. Microsoft recommends that you consider the information in this article before you place Terminal Services in Application Sharing mode on a computer that is running BOS 2000 or SBS 2000.
For the following reasons, Microsoft recommends that you install Terminal Services in Application Sharing mode on a computer that is separate from your computer that is running BOS or SBS:
If you have Microsoft Outlook 2000 running on the same server as Microsoft Exchange 2000 Server, this configuration is not supported because multiple versions of MAPI are installed on the same server.For more information, click the following article number to view the article in the Microsoft Knowledge Base:

All users who can log into the terminal server will have Log On Locally rights to the BOS or SBS server.
Because all users who log on will have Log On Locally rights, they will be able to access data on the drives directly, rather than through the use of shared hard disks; you will have to set the NTFS file system permissions accordingly to prevent users from accessing data directly on the server. This, however, may have an adverse effect on the functionality of SBS.
Users will not be able to install software on their own.
You will need to customize Terminal Server logon scripts. Each time an SBS user logs on, the default SBS logon script will attempt to install any necessary client applications.
By using Terminal Services directly on the BOS or SBS server, you are creating a single point of weakness: If the server is unavailable, users will not have access to any resources to which the server provides access.
Installing Terminal Services in Application Sharing mode on a computer that is running BOS or SBS can greatly reduce the performance of the server because of the additional memory requirements, network traffic, and processor time that is required.
To run Terminal Services in Application Sharing mode, Microsoft recommends that you run it on a stand-alone server (also referred to as a member server), and not a domain controller, a BOS server, or an SBS server; by doing so, this may affect the performance of the server because of the additional memory requirements, network traffic, and processor time that is required by these servers.
Note In a BackOffice MultiServer environment, it is possible to have a BOS server with Terminal Services running in Application Sharing mode. You could set a MultiServer node to use Terminal Services in Application Sharing mode while not using the server applications that were included with BOS. It would be more effective to use Windows 2000, but it is possible to use a BackOffice MultiServer configuration.
