3.1.4.17 NetrServerGetInfo (Opnum 21)

  • Article

The NetrServerGetInfo method retrieves current configuration information for CIFS and SMB Version 1.0 servers.

 NET_API_STATUS NetrServerGetInfo(
   [in, string, unique] SRVSVC_HANDLE ServerName,
   [in] DWORD Level,
   [out, switch_is(Level)] LPSERVER_INFO InfoStruct
 );

ServerName: An SRVSVC_HANDLE (section 2.2.1.1) pointer that identifies the server. The client MUST map this structure to an RPC binding handle (see [C706] sections 4.3.5 and 5.1.5.2).

Level: Specifies the information level of the data. The value of the Level parameter determines the contents of the InfoStruct parameter. This parameter MUST be one of the following values.

Value

Meaning

100

LPSERVER_INFO_100

101

LPSERVER_INFO_101

102

LPSERVER_INFO_102

103

LPSERVER_INFO_103

502

LPSERVER_INFO_502

503

LPSERVER_INFO_503

InfoStruct: This is a structure of type LPSERVER_INFO, as specified in section 2.2.3.7. The content of the InfoStruct parameter is determined by the Level parameter, as the preceding table shows.

Return Values: The method returns 0x00000000 (NERR_Success) to indicate success; otherwise, it returns a nonzero error code. The method can take any specific error code value, as specified in [MS-ERREF] section 2.2. The most common error codes are listed in the following table.

Return value/code

Description

0x00000000

NERR_Success

The client request succeeded.

0x00000005

ERROR_ACCESS_DENIED

Access is denied.

0x0000007C

ERROR_INVALID_LEVEL

The system call level is not correct.

0x00000057

ERROR_INVALID_PARAMETER

The client request failed because the specified parameter is invalid.

0x00000008

ERROR_NOT_ENOUGH_MEMORY

Not enough storage is available to process this command.

In response to the NetrServerGetInfo request, the server MUST return configuration information from the ServerConfiguration object based on the value of the Level parameter.

The value of the Level parameter can be 100, 101, 102, 502, or 503. If the Level parameter has any other value, the server MUST fail the call with an ERROR_INVALID_LEVEL error code.<78>

The value of the Level parameter determines the format of the InfoStruct parameter.

If the value of the Level parameter is 100, the server MUST return its information by filling the SERVER_INFO_100 structure in the ServerInfo100 member of the InfoStruct parameter.

  • If the ServerName parameter is NULL, sv100_name MUST be set to ServerConfiguration.ServerInfo103.sv103_name. Otherwise, sv100_name MUST be set to the value of ServerName.

If the value of the Level parameter is 101, the server MUST return its information by filling the SERVER_INFO_101 structure in the ServerInfo101 member of the InfoStruct parameter.

  • sv101_platform_id MUST be set to ServerConfiguration.ServerInfo103.sv103_platform_id.
