Abstract:

    Netlogon service global variable external and definitions

Author:

    Ported from Lan Man 2.0

Revision History:

    21-May-1991 (cliffv)
        Ported to NT.  Converted to NT style.

    02-Jan-1992 (madana)
        added support for builtin/multidomain replication.
    07-May-1992 JohnRo
        Use net config helpers for NetLogon.

// netlogon.c will #include this file with LSRVDATA_ALLOCATE defined.
// That will cause each of these variables to be allocated.
//
// If we need to allocate data (i.e. LSRVDATA_ALLOCATE is defined) we
// also want to allocate Guids, so define INITGUID.  Also, reinclude
// guiddef.h.  Without guiddef.h reincluded, DEFINE_GUID will be resolved
// from precompiled logonsrv.h that included this file with LSRVDATA_ALLOCATE
// not defined causing only external definition of Guids.  Reincluding
// guiddef.h here forces definition of INITGUID to take effect.
