远程桌面上的证书问题

请参阅此链接: 远程桌面上的证书问题

我有2台电脑与Windows 7旗舰版…(都在NETHOME)
PC 1:计算机名称= alfa – >(主pc),IP = 192.168.0.1
PC 2:计算机名称= beta-lap – >(笔记本电脑),IP = 192.168.0.2
连接types:交叉电缆…

当我想远程从这些PC的其中一个,我得到以下错误:

Full Title : Remote Desktop Connection Body Text : The remote computer could not be authenticated due to problems with its security certificate. It may be unsafe to proceed. Certificate name Name in the certificate from the remote computer: blablabla Certificate errors The following errors were encountered while validating the remote computer's certificate: The certificate is not from a trusted certifying authority. Do you want to connect despite these certificate errors? Don't ask me again for connections to this computer 

我可以通过检查,尽pipe这些证书错误,并查看远程计算机绕过它,但这是正常的?

我该如何解决这个问题?
此外,为什么我在两台PC的系统托盘上的networking连接图标上都有注意图标?
这个小networking有什么问题?
