单位用一台Dell R710服务器，系统为windows server 2008 datacenter 英文版，系统运行hyper-v 虚拟机

机器其中三块网卡，同时连接在一个网段，一块是机器本地址，另两块做虚拟机的网卡

最近发现老自动重启，日志也看不出重启问题。

已经使用dell DSET工具检测过，dell工程是确认过硬件没有问题，

请问各位专家，我可以怎么来排查问题所在？

有如下几个错误

1、Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0xA4BADB43DFCD.  The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from

the network address (DHCP) server.

5、The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

6、warning The time service detected a time difference of greater than 5000 milliseconds for 900 seconds. The time difference might be caused by synchronization with low-accuracy time sources or by suboptimal network conditions. The time service is no longer

synchronized and cannot provide the time to other clients or update the system clock. When a valid time stamp is received from a time service provider, the time service will correct itself.
