Let me start out by stating that I have already searched many sources for information or a resolution, but I have been unable to find a permanent solution.
Problem:
Randomly, for what appears to be no reason, the windows server starts to respond with the error message when it tries to access any network resource. It does not matter if it is a networked drive, a UNC path or a symbolic link. Also, clients cannot reach the server either once this error starts to occur. Remote Desktop states that the machine cannot be found when I try to connect. PING will return the IP assigned, but it states request timed out. There is no information in the windows event log for this error.
The server is a VM running Windows Server 2016. There is only one virtual network card assigned and there are no segmented VLAN’s.
Starting with http://support.microsoft.com/kb/319504 - I realize that this is for an older version of windows, but I do in fact get “system error 68 has occurred” when I execute the command “net use *serverfolder” at the time that the server is producing the error. However, none of the ways to fix the problem work.
I have a hard time believing that all ephemeral ports have been utilized. Executing the command “netsh int ipv4 show dynamicport tcp” currently displays that there are 16384 ports available for use.
Executing “netstat -ano” at the time the server is producing the error displays very few network resources in use (less than 50). The states are either listening or established. There are no sessions or ports stuck in time_wait or close_wait.
Next, https://support.microsoft.com/en-us/help/929851/the-default-dynamic-port-range-for-tcp-ip-has-changed-in-windows-vista. This article confirms what I am seeing for the dynamic range of ports, that it starts with 49152 instead of between 1024 and 5000. It also showed me the netsh command used above.
Most of the Google searches just point me back to support.microsoft.com/kb/319504, which is the first article that I went to or they are for an unrelated product (such as BizTalk or Exchange).
The VM has a light load. There are not many clients connected. The only software that is currently installed is SQL Server 2016.
If I reboot the VM, the error goes away for a few days. Then it comes back. And the really weird thing is, I have 2 VM’s that are acting this way.
The VM host machine is working without error. And all of the other VM’s on that host are working without error. The underlying network has no reported issues either. All machines are on the same domain.
I am at a loss on what is producing the error. Any assistance would be greatly appreciated.
Thanks

The network configuration of your VM is relevant here. Please share it?
Though I'm more familiar with Linux than Windows, if you are using a simple bridge network, I could imagine this happening either due to resource exhaustion caused by one or more other nodes (two VMs and a host sharing an IP, and between them they use up all the ephems), or simply because the ephemeral port the system wishes to use is already in use by another VM or the host itself and Windows naively assumes that it has exclusive rights to all ports, meaning that a failure to bind on min(in_use_port + 1, max_port) unambiguously indicates an exhaustion of ports. The one aspect of this that doesn't fit this hypothesis is that ping isn't responding. Ping is ICMP, and has nothing to do with availability of ephemeral ports, or lack thereof.
