FLEXlm version 9.2.2 on a server/workstation running Windows NT® 4.0?

My question is: Can we install FLEXlm version 9.2.2 on a server/workstation
running Windows NT® 4.0 Service Pack 6a or later or must it be on a
server/workstation running Windows XP Professional? The two documents listed
below are inconsistent.

In the whitepaper "Installing the Autodesk Network License Manager for
AutoCAD 2005 or AutoCAD 2005-Based Products", document
4370792_ACAD2005_Installing_the_Network_License_Manager.pdf, you read in the
middle of page 2

"For the NLM to distribute licenses, it must be installed, configured,
authorized, and started on a Microsoft®
Windows NT® 4.0 workstation or server, Windows® 2000 Professional
workstation or server, Windows XP
Professional, or Windows® 2003 Server. The NLM cannot be installed on a
Novell® or UNIX® server."

In the "Network Administrator's Guide 2005" for Autodesk MapT 3D, document
4244160_acad_nag.pdf, you read in chapter 2 System Requirements page 14

Have anybody experience from Flexlm 9.2.2 and Windows NT 4.0?
