NetLocalGroupSetInfo function

The NetLocalGroupSetInfo function changes the name of an existing local group. The function also associates a comment with a local group.

Syntax


NET_API_STATUS NetLocalGroupSetInfo(
  _In_  LPCWSTR servername,
  _In_  LPCWSTR groupname,
  _In_  DWORD   level,
  _In_  LPBYTE  buf,
  _Out_ LPDWORD parm_err
);

Parameters

servername [in]

Pointer to a constant string that specifies the DNS or NetBIOS name of the remote server on which the function is to execute. If this parameter is NULL, the local computer is used.

groupname [in]

Pointer to a constant string that specifies the name of the local group account to modify. For more information, see the following Remarks section.

level [in]

Specifies the information level of the data. This parameter can be one of the following values.

ValueMeaning
0

Specifies the local group name. The buf parameter points to a LOCALGROUP_INFO_0 structure. Use this level to change the name of an existing local group.

1

Specifies the local group name and a comment to associate with the group. The buf parameter points to a LOCALGROUP_INFO_1 structure.

1002

Specifies a comment to associate with the local group. The buf parameter points to a LOCALGROUP_INFO_1002 structure.

 

buf [in]

Pointer to a buffer that contains the local group information. The format of this data depends on the value of the level parameter. For more information, see Network Management Function Buffers.

parm_err [out]

Pointer to a value that receives the index of the first member of the local group information structure that caused the ERROR_INVALID_PARAMETER error. If this parameter is NULL, the index is not returned on error. For more information, see the following Remarks section.

Return value

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.

Return codeDescription
ERROR_ACCESS_DENIED

The user does not have access to the requested information.

ERROR_INVALID_PARAMETER

One of the function parameters is invalid. For more information, see the following Remarks section.

ERROR_NO_SUCH_ALIAS

The specified local group does not exist.

NERR_NotPrimary

The operation is allowed only on the primary domain controller of the domain.

NERR_InvalidComputer

The computer name is invalid.

 

Remarks

If you call this function on a 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 Domain Admins and Account Operators to call this function. On a member server or workstation, only Administrators and Power Users can call this function. For more information, see Security Requirements for the Network Management Functions. For more information on ACLs, ACEs, and access tokens, see Access Control Model.

The security descriptor of the LocalGroup object is used to perform the access check for this function. Typically, callers must have write access to the entire object for calls to this function to succeed.

To specify the new name of an existing local group, call NetLocalGroupSetInfo with LOCALGROUP_INFO_0 and specify a value using the lgrpi0_name member. If you call the NetLocalGroupSetInfo function with LOCALGROUP_INFO_1 and specify a new value using the lgrpi1_name member, that value will be ignored.

If the NetLocalGroupSetInfo function returns ERROR_INVALID_PARAMETER, you can use the parm_err parameter to indicate the first member of the local group information structure that is invalid. (A local group information structure begins with LOCALGROUP_INFO_ and its format is specified by the level parameter.) The following table lists the values that can be returned in the parm_err parameter and the corresponding structure member that is in error. (The prefix lgrpi*_ indicates that the member can begin with multiple prefixes, for example, lgrpi0_ or lgrpi1_.)

ValueMember
LOCALGROUP_NAME_PARMNUMlgrpi*_name
LOCALGROUP_COMMENT_PARMNUMlgrpi*_comment

 

User account names are limited to 20 characters and group names are limited to 256 characters. In addition, account names cannot be terminated by a period and they cannot include commas or any of the following printable characters: ", /, \, [, ], :, |, <, >, +, =, ;, ?, *. Names also cannot include characters in the range 1-31, which are nonprintable.

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.
