Windows Server 2008 R2 上的 IPv4 静态 IP 地址自发清除

Windows Server 2008 R2 上的 IPv4 静态 IP 地址自发清除

我相信这个问题更适合 superuser.com,但可能它属于 serverfault.com

我有一台运行 Windows Server 2008 R2 的系统,其 IPv4 TCP 设置设为静态 IP 地址。昨晚,它突然失去网络连接,经检查,所有设置都被清除了(IP 地址、子网和网关)。

我是唯一一个对该机器具有管理员访问权限的人,并且最近几天我并没有访问过它。

显然,病毒总是一种下意识的可能性,但我确信系统是干净的。有没有人知道这怎么可能发生?或者至少,我可以在哪里找到更多线索来解释这个问题?

Broadcom BCM5709C:网络链路断开。请检查网络电缆是否连接正确。

因此,Windows 自动更新似乎在这次故障中扮演了一定角色。我不认为问题仅仅是由重启引起的,因为在修复 IP 地址等之后,后续重启并没有解决问题。
