ACCIS SCO Unix vs Microsoft NT
A briefing on the possibilities of
moving the SAC&C Network Server
from SCO Unix as the operating
system to Microsoft Windows NT.
• Can OUSD(A)-SAC&C and ACCIS benefit from a move
to Windows NT as an operating system on the server
as compared to the current situation with SCO Unix?
• Can OUSD(A)-SAC&C and ACCIS be converted to use
Windows NT as the operating system on the server?
• Will Windows NT, as the operating system on the
server, provide the same level of function that we
expect from SCO Unix?
• What are the advantages and disadvantages of moving
to Windows NT?
ACCIS Windows NT
• True 32-bit operating system, does not run “on top of”
• Network compatibility with Novell, Microsoft LAN
Manager, DEC Pathworks, and TCP/IP networks.
• Meets C2 level security right out of the box, share-level
security through Windows NT and user-level through
Windows NT Advanced Server.
• Runs all DOS and Windows Applications.
• Provides same benefits as other “Unix” operating
systems such as SCO Unix.
• Better integration with Microsoft LAN Manager System
Administration software interface which is already
used by DEC Pathworks for SCO Unix.
• Remote Access Improvements
• Advanced System Administration Tools
• Maintenance Improvement
• Support from Microsoft:
– Technical Support Availability and Expertise
– Microsoft Certified Professional Program
– Microsoft Solutions Channel
– Cost is $300 for Windows NT
– Cost is $970 for Windows NT Advanced Server
– Need DEC Pathworks version 5.0 which includes support for NT, may
require additional cost
– CD-ROM should be purchased to install software
– Time delay in delivering network will occur
– Third party vendors may lack NT support currently
ACCIS Technical Advantages
• Better integration with Microsoft LAN Manager
• Database Engine
• NT provides network interface to built-in tools:
– User Manager for workstation security and user management
– Disk Administration for maintenance and management
– Event Viewer for monitoring of applications and security
– Performance Monitor for system measurement and troubleshooting
– Tape Backup for easy access to backup/restore functions
– Third party vendors involved do have NT support
• In the future, there will probably be many more 32-bit
applications written for NT than for Unix.
• Microsoft Network Development Channel

Title: Vendors are ready to connect with NT
• DEC point of contact
• Need Windows NT or NT Advanced Server?
– Answer, NT Advanced Server would be better
• Can we use Advanced Server and DEC Pathworks, will
there be a conflict between the NOS’?
– Answer, No. Actually better connection to MS LAN Manager which is
utilized by Dec Pathworks.
• What is the current on-the-street version of DEC
Pathworks? (5.0 has NT support)
– Answer, version 4.1 is current and has NT support.
• What is the cost to upgrade to DEC Pathworks version
– Answer, not yet available at this time.
• Yes, OUSD(A)-SAC&C and ACCIS can benefit from a
move to Windows NT as an operating system on the
server as compared to the current situation with SCO
• Yes, OUSD(A)-SAC&C and ACCIS can be converted to

• Yes, Windows NT, as the operating system on the
server, can provide the same level of function that we
expect from SCO Unix and even enhance functionality.
• Windows NT brings many more advantages to ACCIS
than disadvantages and the disadvantages are only
short-term and do not affect the system itself.
