我有一个小型网络,有15个工作站,SAMBA AD和一堆虚拟化
Linux服务器.所有工作站和服务器都在同一子网上.
所有工作站都运行Windows 7 Pro
我的Samba 4 DC和ISC-DHCP-SERVER都在同一个虚拟主机上运行.
大多数(如果不是所有)工作站都配置了DHCP预留.
我的一个工作站不会获得dhcp地址.当我启用适配器时,我的DHCP服务器的syslog报告以下内容:(我已经尝试删除dydns脚本,它没有任何区别,所以请忽略这些消息.)

对于这个工作站,我似乎每秒钟充满了10个请求.最终Windows超时,并为自己分配一个169.x.x.x地址,然后退出.
任何见解/建议都是最受欢迎的.
在工作站上我尝试过：更新驱动程序.安装裸操作系统.禁用无线网卡.在HKLM-System-Current Control Set-Services-TCPIP-Parameters-interfaces-GUID中应用注册表设置“DhcpConnEnableBcastFlagToggle为1”.
在服务器上我尝试更新DHCP服务器.我现在在3.3-5ubuntu12.7
我调查了不同的延迟设置,但它们似乎没有帮助.
dhcpd.conf如下:(已删除其他预订)

我没有在客户端上看到任何看起来相关的事件日志.
我已经尝试将预留IP更改为192.168.1.6 – 客户端仍然使用dhcp服务器大约30秒,但最终会接受IP.我正在寻找192.168.1.249的可能重复 – 但尚未能找到一个.这是星期天,办公室里没有其他人,所以这可能是其中一部分原因.
我还添加了建议的注册表项.
更新：2018年1月7日12:40
我太庆祝了.我重新启动了客户端,它不再接受IP
更新2018年1月7日13:45
在请求IP 15分钟后,客户端最终接受了IP.记录下面的日志：

更改了NIC,使用新NIC的MAC更新了预留.
结果相同.
更新2018年1月8日9:45
更新2018年1月9日
我已经获得了2014年1月13日的停电窗口.直到15日才更新
更新2018年1月14日
我尝试重新启动交换机和物理服务器.仍然没有变化.
然后我为服务器分配了自己的物理网卡/交换机端口.仍然没有变化.
然后我查看了交换机配置,并将端口设置重新应用到正在使用的端口,并且洪水似乎已经停止.我还不相信,并会监视几天.
在我看来工作站中的网卡坏了.
尝试更新固件,如果仍然无法更改NIC.
