* Windows XP PDC server: "Windows 5.1"
* Windows .Net: "Windows .NET 3621"
* Windows .Net: "Windows .NET 3718"
*
* DAVE (Thursby Software: CIFS for MacOS) uses "MacOS", sometimes with a
* version number appended, i.e. "MacOS 8.5.1". We treat DAVE like NT 4.0
* except for the cases that DAVE clients set 'watch tree' flag in notify
* change requests.
*
* Samba reports UNIX as its Native OS, which we can map to NT 4.0.
