Abstract:
|
|
|
|
This file contains routines to implement remote versions of the LanMan
|
|
domain APIs on downlevel servers. The APIs are RxNetGetDCName and
|
|
RxNetLogonEnum.

|
|
Environment:
|
|
|
|
Portable to any flat, 32-bit environment. (Uses Win32 typedefs.)
|
|
Requires ANSI C extensions: slash-slash comments, long external names.

|
|
Implement downlevel NetGetDCName.
|
|
27-Jul-1991 JohnRo
|
|
Made changes suggested by PC-LINT.
|
|
07-Feb-1992 JohnRo
|
|
Use NetApiBufferAllocate() instead of private version.
|
|
01-Sep-1992 JohnRo
|
|
RAID 5088: NetGetDCName to downlevel doesn't UNICODE translate.
|
|
Minor debug output fix.
|
|
Changed to use _PREFIX equates.

Routine Description:
|
|
|
|
RxNetGetDCName performs the same function as NetGetDCName, except that the
|
|
server name is known to refer to a downlevel server.
|
|
|
|
Arguments:
|
|
|
|
UncServerName - Same as NetGetDCName, except UncServerName must not be
|
|
null, and must not refer to the local computer.
|
|
|
|
OptionalDomain - Same as NetGetDCName.
|
|
|
|
BufPtr - Same as NetGetDCName.
|
|
|
|
Return Value:
|
|
|
|
NET_API_STATUS - Same as NetGetDCName.
