COSERVERINFO  WKGRAJ

Identifies a remote machine resource to the new or enhanced activation functions. The structure is defined as follows in the Wtypes.h header file:

typedef struct  _COSERVERINFO

   

    DWORD dwReserved1;

    LPWSTR pwszName;

    COAUTHINFO  *pAuthInfo;

    DWORD dwReserved2;

    }   COSERVERINFO;

 

Members

dwReserved1

Reserved for future use. Must be 0.

pszName

Pointer to the name of the machine to be used.

pAuthInfo

When using NTLMSSP, this value must be set to zero. A non-zero value, which is a pointer to a COAUTHINFOOXW4H1 structure, would only be used when a security package other than NTLMSSP is being used.

dwReserved2

Reserved for future use. Must be 0.

 

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 ( \\server  or  server ) and DNS names ( server.com ,  www.foo.com , or  135.5.33.19 ) names are allowed.

If you are using the NTLMSSP security package, the default case, the pAuthinfo parameter should be set to zero. If you are a vendor supporting another security package, refer to COAUTHINFOOXW4H1. The mechanism described there is intended to allow DCOM activations to work correctly with security providers other than NTLMSSP, or to specify additional security information used during remote activations for interoperability with alternate implementations of DCOM. If pAuthInfo is set, those values will be used to specify the authentication settings for the remote call.  These settings will be passed to RpcBindingSetAuthInfoEx.

If the pAuthInfo field is not specified, any values in the AppIDBQF3ZC section of the registry will be used to override the following default authentication settings:

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
