CoInitializeSecurity 的小问题

[liweiwei0808]

客户端访问远程服务器，由于CoInitializeSecurity 的原因，配置DCOM时，有时成功不了，客户端代码如下；
hr = CoInitializeSecurity(NULL,-1,NULL,NULL,RPC_C_AUTHN_LEVEL_NONE,
RPC_C_IMP_LEVEL_IDENTIFY,
NULL,
EOAC_ACCESS_CONTROL,
NULL);

1 如果服务器和客户端不考虑安全的话，服务器和客户端的CoInitializeSecurity的参数应该如何填写？
2 如果不考虑安全配置DCOM时会不简单点？

// Turn security off so that everyone has access to us

CoInitializeSecurity(NULL, -1, NULL, NULL, RPC_C_AUTHN_LEVEL_NONE,
RPC_C_IMP_LEVEL_IMPERSONATE, NULL, EOAC_NONE, NULL);

// This provides a NULL DACL which will allow access to everyone.

CSecurityDescriptor sd;
sd.InitializeFromThreadToken();
hr = CoInitializeSecurity(sd, -1, NULL, NULL,
RPC_C_AUTHN_LEVEL_PKT, RPC_C_IMP_LEVEL_IMPERSONATE, NULL, EOAC_NONE, NULL);
_ASSERTE(SUCCEEDED(hr));
