as a networking operating system, Windows NT 3.1 supports multiple network protocols. Besides IPX/SPX and NetBEUI, the TCP/IP protocol is supported allowing access to the Internet. Similar to Windows for Workgroups, files and printers can be shared and the access rights and configuration of these resources can be edited over the network. When a network printer is installed, the required drivers are automatically transferred over the network, removing the need to manually install the drivers for every computer. The Remote Access Service (RAS) allows a client from outside the network to connect to the network using a modem, ISDN or X.25 and access its resources. While the workstation allows one RAS connection at a time, the server supports 64. Windows NT 3.1 supports the then-new Unicode standard, a character set which allows multiple languages to be displayed. This facilitates localization of the operating system. All strings, as well as file and folder names, are internally processed in Unicode, but the included programs, like the File Manager, are not Unicode aware, so folders containing Unicode characters cannot be accessed. For demonstration purposes, a Unicode typeface called Lucida Sans Unicode is shipped with Windows NT 3.1 even though it is not installed by default. The previous code pages are still supported for compatibility purposes. The Windows registry, introduced with Windows NT 3.1, is a central, hierarchical configuration database designed to allow configuration of computers over the network and to replace the commonly-used text-based configuration files, like INI files, AUTOEXEC.BAT and CONFIG.SYS. Using the undocumented registry editor, the Windows registry can be viewed and edited by the user. The Advanced Server is designed to manage the workstation computers. It can function as a Domain controller, where all users and groups as well as their rights are stored. This way, a user can log on from any computer in the network, and users can be managed centrally on the server. Trust relationships can be built to other domains to be able to exchange data cross-domain. Using the replication service, files like logon scripts can be synchronized across all computers on the network. The Advanced Server supports the AppleTalk protocol to allow connections to Macintosh computers. Hard drives can be combined to RAIDs in Windows NT 3.1 Advanced Server, the supported configurations are RAID 0, RAID 1 and RAID 5. Included programs Windows NT 3.1, for the most part, comes with 32-bit versions of the
