SUMMARY
XACTSRV, the service that supports remote net APIs from MS-DOS and
OS/2 (for example, NET VIEW \\NTSERVER), is now part of the Windows NT
server service. It is no longer necessary to use the NET START XACTSRV
command to enable your server to be administered from downlevel
clients. The XACTSRV capability is started automatically when the
server is started.
You can disable this feature by running the Windows NT Registry Editor
(REGEDT32.EXE) and changing the \Registry\MACHINE\SYSTEM\CurrentControl
Set\Services\LanmanServer parameter as follows:
AcceptDownlevelApis = REG_DWORD 0
WARNING: Using Registry Editor incorrectly can cause serious, system-wide
problems that may require you to reinstall Windows NT to correct them.
Microsoft cannot guarantee that any problems resulting from the use of
Registry Editor can be solved. Use this tool at your own risk.
One effect of this change is that print-queue shares are now
persistent. If you set up a printer and share it with the network
using Print Manager, that share is automatically re-created when
you restart the system.
