[This function is provided only for backward compatibility with Windows NT Server 4.0. It returns ERROR_CALL_NOT_IMPLEMENTED on Windows Server 2003. Applications should use the MprAdminGetPDCServer function.]

The RasAdminGetUserAccountServer function retrieves the name of the server that has the user account database. Use the returned server name in the RasAdminUserGetInfo and RasAdminUserSetInfo functions to get or set information about a specified user.

Syntax

DWORD RasAdminGetUserAccountServer(
  _In_  const WCHAR  *lpszDomain,
  _In_  const WCHAR  *lpszServer,
  _Out_       LPWSTR lpszUserAccountServer
);

Parameters

lpszDomain [in]: Pointer to a null-terminated Unicode string that specifies the name of the domain to which the RAS server belongs. This parameter is NULL for the RAS administration applications running on workstations or servers that are not members of a domain. If this parameter is NULL, the lpszServer parameter must be non-NULL.
lpszServer [in]: Pointer to a null-terminated Unicode string that specifies the name of the RAS server. Specify the name with leading "\\" characters, in the form: \\servername. This parameter can be NULL if the lpszDomain parameter is not NULL.
lpszUserAccountServer [out]: Pointer to a buffer that receives a null-terminated Unicode string that specifies the name of a domain controller that has the user account database. The buffer should be big enough to hold the server name (UNCLEN +1). The function prefixes the returned server name with leading "\\" characters, in the form: \\servername.

Return value

If the function succeeds, the return value is ERROR_SUCCESS.

If the function fails, the return value can be the following error code.

Value	Meaning
ERROR_INVALID_PARAMETER	Both lpszDomain and lpszServer are NULL.

There is no extended error information for this function; do not call GetLastError.

Remarks

The RasAdminGetUserAccountServer function obtains the name of the server with the user accounts database. This function requires the name of the RAS server or the name of the domain in which the RAS server resides.

The lpszDomain parameter should specify a valid domain name. This parameter is NULL for RAS administration applications running on servers that are not members of a domain (for example, the server is in its own workgroup). In this case, the lpszServer parameter must specify the server name. To get the server name, call the GetComputerName function. Be sure to prefix the server name with the "\\" characters.

If the server name specified by lpszServer is a stand-alone server (that is, the server or workstation is not a member of a domain), then the server name itself is returned in the lpszUserAccountServer buffer.

Then use the name of the user account server in a call to the NetQueryDisplayInformation function to enumerate the users in the user account database.
