COSERVERINFO

  • Article

This structure is used to identify a remote machine resource to the new or enhanced activation functions.

typedef struct _COSERVERINFO {
  DWORD dwReserved1;
  LPWSTR pwszName;
  COAUTHINFO* pAuthInfo;
  DWORD dwReserved2;
} COSERVERINFO;

Members

  • dwReserved1
    Reserved for future use; set to zero.
  • pwszName
    Pointer to the name of the machine to be used.
  • pAuthInfo
    Set to a pointer to a COAUTHINFO structure to override the default activation security for machine remote activations. Otherwise, set to NULL to indicate that default values should be used. For more information, see the Remarks section.
  • dwReserved2
    Reserved for future use; set to zero.

Remarks

The COSERVERINFO structure is used primarily to identify a remote system in object creation functions. Machine resources are named using the naming scheme of the network transport. By default, all UNC and DNS names are allowed.

If pAuthInfo is set to NULL, NTLMSSP with the identity of the actual client will be used. To meet any one of the needs in the following list, pAuthInfo can be set to point to a non-NULL COAUTHINFO structure:

  • To specify a different client identity for machine remote activations. The specified identity will be used for the launch permission check on the server rather than the real client identity.
  • To specify that Kerberos, rather than NTLMSSP, is used for machine remote activation. A nondefault client identity may or may not be specified.
  • To request unsecure activation.
  • To specify a proprietary authentication service.

If pAuthInfo is not NULL, those values will be used to specify the authentication settings for the remote call. These settings will be passed to RpcBindingSetAuthInfoEx.

If the pAuthInfo member is not specified, any values in the AppID section of the registry will be used to override default authentication settings. The following table shows the settings that will be overridden.

pAhuthInfo Member Setting
dwAuthnSvc RPC_C_AUTHN_WINNT
dwAuthzSvc RPC_C_AUTHZ_NONE
pszServerPrincName NULL
dwAuthnLevel RPC_C_AUTHN_LEVEL_CONNECT
dwImpersonationLevel RPC_C_IMP_LEVEL_IMPERSONATE
pvAuthIdentityData NULL
dwCapabilities RPC_C_QOS_CAPABILITIES_DEFAULT

Requirements

OS Versions: Windows CE 2.0 and later.
Header: Wtypes.h.
