The architecture of Windows for Workgroups is essentially the same as that of Windows 3.1 except for the networking subsystem, which supports the newer NDIS 3 standard. Windows for Workgroups also includes enhancements to 32-bit disk access, which is implemented as two Windows virtual device drivers (VxDs): VFAT, a 32-bit, protected-mode replacement for the MS-DOS file allocation table (FAT) file system, and VCACHE, which replaces the MS-DOS SmartDrive disk-caching utility and improves disk input/output (I/O). The network redirector (VREDIR) is implemented as a file system driver as well. The Installable File System (IFS) manager maintains a table that identifies which type of file system device is associated with each disk volume and forwards all I/O calls to the appropriate device.
You can add support for advanced TCP/IP features such as Dynamic Host Configuration Protocol (DHCP), Telnet, and File Transfer Protocol (FTP) by using the Microsoft TCP/IP-32 for Windows for Workgroups add-on. You can create the installation disks for this add-on by using Network Client Administrator in Windows NT.
