3.1.4 Message Processing Events and Sequencing Rules

This DCOM interface inherits the IUnknown interface. Method opnum field values start with 3; opnum values 0 through 2 represent the IUnknown_QueryInterface, IUnknown_AddRef, and IUnknown_Release methods, respectively, as specified in [MS-DCOM].

Methods with opnum field values 34 through 39 are defined in section 3.3.4, and field value 40 is defined in section 3.5.4.

This protocol MUST indicate to the RPC runtime that it is to perform a strict Network Data Representation (NDR) data consistency check at target level 5.0, as specified in [MS-RPCE] section 3.

Methods in RPC Opnum Order

Method	Description
AddKey	Creates a node and adds it to the metabase as a subnode of an existing node at the specified path. Opnum: 3
DeleteKey	Deletes a node and all its data from the metabase. All of the node's subnodes are recursively deleted. Opnum: 4
DeleteChildKeys	Deletes all subnodes of the specified node and any data they contain. It also recursively deletes all nodes below the subnodes. Opnum: 5
EnumKeys	Enumerates the subnodes of the specified node. Opnum: 6
CopyKey	Copies or moves a node, including its subnodes and data, to a specified destination. The copied or moved node becomes a subnode of the destination node. Opnum: 7
RenameKey	Renames a node in the metabase. Opnum: 8
R_SetData	Sets a data item for a particular node in the metabase. Opnum: 9
R_GetData	Returns a data entry from a particular node in the metabase. Opnum: 10
DeleteData	Deletes specific data entries from a node in the metabase. Opnum: 11
R_EnumData	Enumerates the data entries of a node in the metabase. Opnum: 12
R_GetAllData	Returns all data associated with a node in the metabase, including all values that the node inherits. Opnum: 13
DeleteAllData	Deletes all or a subset of local data associated with a particular node. Opnum: 14
CopyData	Copies or moves data between nodes. Opnum: 15
GetDataPaths	Returns the paths of all nodes in the subtree relative to a specified starting node that contains the supplied identifier. Opnum: 16
OpenKey	Opens a node for read access, write access, or both. The returned handle can be used by several of the other methods in IMSAdminBaseW. Opnum: 17
CloseKey	Closes a handle to a node. Opnum: 18
ChangePermissions	Changes permissions on an open handle. Opnum: 19
SaveData	Explicitly saves the metabase data to disk. Opnum: 20
GetHandleInfo	Returns information associated with the specified metabase handle. Opnum: 21
GetSystemChangeNumber	Returns the number of changes made to data since the metabase was created. Opnum: 22
GetDataSetNumber	Returns all the data set numbers associated with a node in the metabase. Opnum: 23
SetLastChangeTime	Sets the last change time associated with a node in the metabase. Opnum: 24
GetLastChangeTime	Returns the last change time associated with a node in the metabase. Opnum: 25
R_KeyExchangePhase1	Receives a pair of encrypted client nodes and returns server encryption and session keys. Opnum: 26
R_KeyExchangePhase2	Receives the encrypted client session and hash keys in response to R_KeyExchangePhase1 and returns the encrypted server hash keys. Opnum: 27
Backup	Backs up the metabase to a specified location. Opnum: 28
Restore	Restores the metabase from a backup. Opnum: 29
EnumBackups	Enumerates the metabase backups in a specified backup location, or in all backup locations. Opnum: 30
DeleteBackup	Deletes a metabase backup from a backup location. Opnum: 31
UnmarshalInterface	Unmarshals a reference to the IMSAdminBaseW interface. Opnum: 32
R_GetServerGuid	Returns the GUID for the IIS instance that is running. Opnum: 33

Structures

The Message Processing Events and Sequencing Rules interface defines the following structures.

Structure	Description
METADATA_HANDLE_INFO	Defines information about a handle to a metabase entry.
METADATA_RECORD	Defines information about a metabase entry.
METADATA_GETALL_RECORD	Defines an analogous structure to METADATA_RECORD but is used only to return data from a call to the R_GetAllData method.
IIS_CRYPTO_BLOB	Defines a block of opaque data, possibly encrypted, for RPC marshaling between IIS and a client.
