Platform SDK: Network Management

NetGroupAdd

The NetGroupAdd function creates a global group in the security database.

Security Requirements

Windows NT: Only members of the Administrators or Account Operators local group can successfully execute the NetGroupAdd function.

Windows 2000: If you call this function on a Windows 2000 domain controller that is running Active Directory, access is allowed or denied based on the access-control list (ACL) for the securable object. The default ACL permits only Administrators and account operators to call this function. On a member server or workstation, only Administrators and account operators can call this function. For more information, see Security Requirements for the Network Management Functions.

NET_API_STATUS NetGroupAdd(
  LPCWSTR servername, 
  DWORD level,        
  LPBYTE buf,         
  LPDWORD parm_err    
);

Parameters

servername
[in] Pointer to a constant null-terminated Unicode character string specifying the name of the remote server on which the function is to execute. The string must begin with \\. If this parameter is NULL, the local computer is used.
level
[in] Specifies the information level of the data. This parameter can be one of the following values.
Value Meaning
0 Specifies a global group name. The buf parameter contains a pointer to a GROUP_INFO_0 structure.
1 Specifies a global group name and a comment. The buf parameter contains a pointer to a GROUP_INFO_1 structure.
2 Specifies detailed information about the global group. The buf parameter contains a pointer to a GROUP_INFO_2 structure.

buf
[in] Pointer to a buffer that contains the data. The format of this data depends on the value of the level parameter.
parm_err
[out] Pointer to a DWORD value that receives the index of the first member of the global group information structure in error when ERROR_INVALID_PARAMETER is returned. If this parameter is NULL, the index is not returned on error. For more information, see the NetGroupSetInfo function.

Return Values

If the function succeeds, the return value is NERR_Success.

If the function fails, the return value can be one of the following error codes.

Value Meaning
ERROR_ACCESS_DENIED The user does not have access to the requested information.
NERR_InvalidComputer The computer name is invalid.
NERR_GroupExists The global group already exists.
NERR_NotPrimary The operation is allowed only on the primary domain controller of the domain.
ERROR_INVALID_LEVEL The value specified for the level parameter is invalid.
NERR_SpeGroupOp The operation is not allowed on certain special groups. These groups include user groups, admin groups, local groups, and guest groups.

Remarks

If you are programming for Active Directory, you may be able to call certain Active Directory Service Interface (ADSI) methods to achieve the same functionality you can achieve by calling the network management group functions. For more information, see IADsGroup.

Requirements

  Windows NT/2000: Requires Windows NT 3.1 or later.
  Windows 95/98: Unsupported.
  Header: Declared in Lmaccess.h; include Lm.h.
  Library: Use Netapi32.lib.
