NFS Client for Windows 95/98 and Windows NT
Try It Free
DiskAccess is Y2K Compliant
 Intergraph has redefined the way the Network File System (NFS®) operates in a Windows® environment, setting the standard for Windows and UNIX interoperability. In today's multivendor working environments, NFS support is essential. As a developer of CAD products on RISC-based UNIX systems and the leading developer of products for Microsoft's 32-bit Windows environment, Intergraph understands the need to share data between Windows and UNIX systems. DiskAccess and our other AccessNFS Solutions were developed to meet the demanding needs of the corporate user.

If you need to integrate Microsoft Windows 95/98 or Windows NT® systems into multivendor networks and access file and print resources on UNIX and mainframe hosts, then you need DiskAccess. DiskAccess is Intergraph's NFS client for the Windows environment. A member of Intergraph's AccessNFS Solutions software family, DiskAccess gives Windows users network-based access to NFS-based file and print resources.

With DiskAccess you can browse NFS file systems without committing a drive letter, accessing network resources only when you need them. Or you can have the option of establishing a full-time link to your server. Browsed connections are mounted and unmounted automatically, and frequently accessed NFS folders or files can be added as a short-cut to the desktop. This approach makes accessing resources easier, reduces NFS server load, and improves overall network performance.

Intergraph's NFS Client Solution
DiskAccess enables Windows 95/98 and Windows NT systems to perform as NFS clients, so you can access file and print resources located on UNIX servers, mainframes, or other NFS-based server systems. Using NFS, DiskAccess sets a new standard for performance.

DiskAccess fully incorporates NFS into the Windows environment, bringing new levels of integration to mixed networking environments. You can connect to resources with drag-and-drop ease and manage file permissions from within Windows property sheets. Using Windows Explorer, Network Neighborhood (click here for image), or File Manager (click here for image), you can browse and connect to file systems and printers located on UNIX or other NFS systems.

Technically Superior
With DiskAccess, it is now possible to gain path-based (UNC) access to NFS files. Connections are automatically opened to NFS drives from desktop shortcuts and OLE-linked objects providing transparent access to NFS host systems. DiskAccess also makes NFS file access behave more like UNIX, with symbolic link support and automatic mounting when linked files are located on alternate servers.

DiskAccess diagram Multithreaded Design for Enhanced Performance The 32-bit Windows operating system is a powerful multitasking environment, but single-threaded processes cannot take advantage of this capability. DiskAccess is a multithreaded design that gives you optimum performance and ensures compatibility.

On Windows 95/98, DiskAccess is implemented as a Virtual Device Driver (VxD), providing maximum performance in a minimum memory space. On Windows NT, DiskAccess is implemented as a system service. These operating system-specific implementations allow DiskAccess to run at the most privileged CPU mode (ring 0).

Native TCP/IP Ensures Compatibility
DiskAccess takes advantage of Microsoft's native TCP/IP protocol stack, ensuring quicker installation, the fewest compatibility problems with third-party applications, and the broadest support for industry network adapters.

Based on Industry Standards
NFS is an industry-standard protocol. Based on Open Network Computing/ Network File System (ONC/NFS) standards, NFS integrates Windows NT systems into multivendor client/server networks, enabling an open exchange of files and network resources among Windows NT systems, UNIX systems, and mainframe hosts.

Digital Terminal Emulation
DiskAccess includes a powerful, versatile terminal emulator with support for VT320, VT220, VT102, VT100, VT52, SCOANSI, BBSANSI, printing, custom keyboard mapping, and command scripting. The terminal emulator also supports 80- and 132-column widths, custom color mapping, and WordPerfect mode. Most common file transfer protocols are supported, including ASCII, Kermit, Xmodem, Ymodem, and Zmodem. Intergraph's telnet emulation is state-of-the-art!

"Great product. DiskAccess has
become an indispensable tool."

IBM Terminal Emulation
IBM terminal emulation provides direct connection to IBM host systems using telnet and TCP/IP. Once connected, Windows users can access all applications available to IBM terminal users. By simply opening a window, users can view, edit, and transfer files from the remote IBM system. Telnet 3270 satisfies mainframe connection needs, providing full color GDDM graphics support. Telnet 5250 connects Windows users to IBM S36-, S38-,and AS400-class systems. Both products emulate the screen, status, and keyboard functions of IBM terminals, making IBM connections fast and easy to use.

File Transfer Protocol
Transferring files between foreign networks, navigating firewalls, and establishing anonymous connections require file transfer protocol (ftp). Intergraph's ftp uses an easy-to-use Windows interface to access ftp servers. Sending and retrieving files can be accomplished with only a few mouse-clicks.

Network Time Protocol
DiskAccess provides an ntp client to synchronize time within the network. This means time stamps are synchronized between systems, ensuring that file creation and modify times are consistent among all the systems on your network and allowing more accurate tracking of revisions.

Remote Shell Daemon and Remote Copy Support
Remote Shell Daemon (rshd) gives users a mechanism for remote users to execute DOS commands. Remote Copy Protocol (rcp) allows files to be copied between remote systems without having to log on to the server or mount a network drive. DiskAccess also includes utilities to convert text files between UNIX and DOS.
