Da, svi znamo za NTTune ili NTSwitch, no što on zapravo radi ...

OVO JE SAMO INFORMATIVNO I EDUKACISKO

Code:

The following is how to trick NT4 to make NTW = NTS by
  changing the Registry settings.

  FYI the worker threads that guard the Registry settings
  HKEY_LOCAL_MACHINE/SYSTEM/Setup/SystemPrefix and
  HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/ProductOptions/
  ProductType do take changes back immmediatly after you make them.
  Further the thread that guards the ProductType setting issues a 
  warning if anything is changed in the ProductOptions section.

  For testing purposes do the following to make my NT4
  Workstation 'behave' like an NT4 Server:

  1) Write down the following settings in your Registry:
     (values for my PC in parentheses)

    HKEY_LOCAL_MACHINE/SYSTEM/Setup/SystemPrefix: (REG_BINARY:
    D71B0000000032D8)

    HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/ProductOptions/Produ
    ctType: (REG_SZ: WinNT)

  2) Make a copy of each entry as:

    HKEY_LOCAL_MACHINE/SYSTEM/Setup/SxstemPrefiy: (REG_BINARY:
    D71B0000000032D8)
    HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/PorductOptions/
    Type: (REG_SZ: WinNT)

    (Notice the exchange of 'x' and 'y' in "SxstemPrefiy" and 'o' and
    'r' in "PorductType"!)

  3) go to directory %SystemRoot%System32, copy ntoskrnl.exe to
     ntoskrnl.pat

  4) Patch ntoskrnl.pat in the following locations (offsets) to reflect
     the above changes:

     exchange 0x053088 and 0x05309C    ('SxstemPrefiy') exchange
     0x052F16 and 0x052F18    ('PorductOptions') exchange 0x0BEB2E and
     0x0BEB42    ('SxstemPrefiy') exchange 0x0BEBB0 and 0x0BEBB2
     ('ProductOptions')

     (the *exchanging* is necessary to make the NTOSKRNL.EXE not to
     appear corrupt, so the checksum does match)

  5) rename ntoskrnl.exe to ntoskrnl.org (it is in use by the system, so
     you can only rename it)

  6) rename ntoskrnl.pat to ntoskrnl.exe (this is to boot with our
     patched version)

  7) shut down and reboot your system Notice: if your system is on a
     NTFS partition, be sure to have a second 'Maintainance NT' installed
     to undo the above changes in case of a failure.

  8) After rebooting, make the following changes to the registry (notice
     the guard thread watches
     'SxstemPrefix' and 'PorductOptions' now):

    HKEY_LOCAL_MACHINE/SYSTEM/Setup/SystemPrefix: (REG_BINARY:
    D71B0000000032DC) "change D8 to DC!]
    HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/ProductOptions/
    ProductType: (REG_SZ: ServerNT)

  9) go to %SystemRoot%System32, rename ntoskrnl.exe to ntoskrnl.pat
     and rename ntoskrnl.org to
     ntoskrnl.exe.

  10) Shut down and reboot. You should see no logon screen during login
      but now you have an NT Server.

Microsoft je još 1996. priznao da je kernel NT Srv i Wks isti ("dele istu arhitekturu"), zato i licenca ima u vidu takve majmunarije po sistemu, pa se dobija robija za zezanje (varanje s licencama, tj omogućavanje više konekcija).

Mnogo je jednostavnije napraviti jedan kernel, pa ga "osakatiti", nego dva. Ovo je i politika najvećeg prijatelja, Intela - koji radi isto to samo sa procesorima. Nema tu nikakvog otkrića. Limitiranje broja konekcija je samo poslovni potez, a kad kažemo workstation i server, pa tu se misli i na gomilu servisa i alata koji dolaze uz server.

da, da o DNS, DHCP server, RIS, Active Directory ne govorimo ...

Citat:

This program will change the operating system type on your computer.

You can turn a Windows NT Workstation (or a Windows 2000 Professional)
installation into a Server environment and vice versa.

While the software has been tested on NT4 and Windows 2000 installations,
there are no guarantees that it will work on your system. USE AT YOUR
OWN RISK!

The software also appears to turn Windows XP Professional into "Windows
Whistler Server", but the resulting operating system is not fully
functional. DO NOT USE THIS PROGRAM ON WINDOWS XP UNLESS YOU ARE WILLING
TO REINSTALL THE OPERATING SYSTEM.

REASON: It's a well-known fact that Microsoft's Windows Workstation and
Windows Server products share the same binaries - the only difference
lies in the registry. The sole reason for the creation of this software
is to demonstrate this fact to the public.

LEGAL: The software is provided "as is". Neither explicit nor implicit
warranties are granted. USE AT YOUR OWN RISK! No right is granted to sell
or redistribute this software in any form.
