COSERVERINFO structure (objidl.h)
Identifies a remote computer resource to the activation functions.
Syntax
typedef struct _COSERVERINFO {
DWORD dwReserved1;
LPWSTR pwszName;
COAUTHINFO *pAuthInfo;
DWORD dwReserved2;
} COSERVERINFO;
Members
dwReserved1
This member is reserved and must be 0.
pwszName
The name of the computer.
pAuthInfo
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
This member is reserved and must be 0.
Remarks
The COSERVERINFO structure is used primarily to identify a remote system in object creation functions. Computer resources are named using the naming scheme of the network transport. By default, all UNC ("\\server" or "server") and DNS names ("domain.com", "example.microsoft.com", or "135.5.33.19") names are allowed.
If pAuthInfo is set to NULL, Snego will be used to negotiate an authentication service that will work between the client and server. However, a non-NULLCOAUTHINFO structure can be specified for pAuthInfo to meet any one of the following needs:
- To specify a different client identity for computer 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 the pAuthInfo parameter is NULL, then dwAuthnLevel can be overridden by the authentication level set by the CoInitializeSecurity function. If the CoInitializeSecurity function isn't called, then the authentication level specified under the AppID registry key is used, if it exists.
Starting with Windows XP with Service Pack 2 (SP2), dwAuthnLevel is the maximum of RPC_C_AUTHN_LEVEL_CONNECT and the process-wide authentication level of the client process that is issuing the activation request. For earlier versions of the operating system, this is RPC_C_AUTHN_LEVEL_CONNECT.
