Platform SDK: Network Management

NetLocalGroupAdd

The NetLocalGroupAdd function creates a local group in the security database.

Security Requirements

Windows NT: Only members of the Administrators or Account Operators local group can successfully execute the NetLocalGroupAdd 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 NetLocalGroupAdd(
  LPCWSTR servername, 
  DWORD level,        
  LPBYTE buf,         
  LPDWORD parm_err    
);

Parameters

servername

[in] Pointer to a constant 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 local group name. The buf parameter points to a LOCALGROUP_INFO_0 structure.
1	Specifies a local group name and a comment to associate with the group. The buf parameter points to a LOCALGROUP_INFO_1 structure.

buf

[in] Pointer to a buffer containing the local group information structure. 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 local group information structure to cause the ERROR_INVALID_PARAMETER error. If this parameter is NULL, the index is not returned on error. For more information, see the Remarks section in the NetLocalGroupSetInfo topic.

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_NotPrimary	The operation is allowed only on the primary domain controller of the domain.
NERR_GroupExists	The local group already exists.
ERROR_ALIAS_EXISTS	The local group already exists.

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 local group functions. For more information, see IADsGroup.
