    <description>&lt;P&gt;I hope the community can help me resolve a problem I'm having with one of my virtual machines. I'll describe the problem the best I can, but my knowledge of esxi/vmware/vcenter is limited and my terminology may not be up to par.&lt;/P&gt;&lt;P&gt;I have a Dell R730xd running ESXi 6.7 and vCenter 7. There are three VM's running: Server 2012r2, Server 2016 and a Windows 7 x32 vm, along with vCenter. They all share the same virtual network, and I have only one physical network connection to the LAN.&lt;/P&gt;&lt;P&gt;The Windows 7 x32 vm is running some archaic software (GreatPlains 9.1) that the business owner still need to access and only runs in x32 via a DOS window. This VM also has several shared network folders.&lt;/P&gt;&lt;P&gt;The Server 2012r2 and Server 2016 run fine with no connectivity issues, and I can PING them with no drops or time outs, and terminal services run fine.&lt;/P&gt;&lt;P&gt;The Windows 7 x32 vm started having problems in early February of this year. Mind you, these VMs have been running fine for the last 3 years.&lt;/P&gt;&lt;P&gt;Pining the Windows 7 x32 vm from my workstation results in random "Request timed out." errors. Its very random. I can have a slew of good replies, then a block of time outs. When logged into the VM via Remote Desktop, I suffer multiple connection dropped, attempting to reconnect problems.&lt;/P&gt;&lt;P&gt;Curiously, if I log into my Server 2016 instance and ping the IP of the Windows 7 instance, I have no time outs. This tells me that the problem is the traffic going out of the VM to my LAN, but only with the Windows 7 vm.&lt;/P&gt;&lt;P&gt;I'm at a loss after many days trying to figure this out. My co-worker who is much more knowledgeable and experience with vmWare is also stumped.&lt;/P&gt;&lt;P&gt;I hope someone can point me in the right direction to fix this problem. Thank you.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;A couple of things.&lt;/P&gt;&lt;P&gt;1 . The network adapter of all three VMs is the same, is there any difference?&lt;/P&gt;&lt;P&gt;2 Try creating the new network adapter with windows 7 and assign some new IP (separate subnet) and check if there is any ping drop?&lt;/P&gt;&lt;P&gt;3, From the ESXi host, run esxtop and validate if the eth0 of the VMs are using separate vmnic?&lt;/P&gt;&lt;P&gt;4 Update all the network drivers within the guest OS.&lt;/P&gt;&lt;P&gt;5. Check the hardware version of the VM (&lt;A href="https://kb.vmware.com/s/article/1003746" target="_blank"&gt;https://kb.vmware.com/s/article/1003746&lt;/A&gt;)&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Regards&lt;/P&gt;&lt;P&gt;Harry&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>
