      Sounds like a VMQ issue.

        This is Server 2016 and Intel... I hadn't heard of anything but broadcom with the vmq issue.

          It still can happen on Intel or Server 2016. Have you also installed the latest LAN drivers too?

            Yes, LAN drivers are up to date. I'll try the VMQ and also unteaming.

            Nothing looks glaringly wrong?

              That VMQ thing can be an issue on 1 GB NICs with out-dated firmware/drivers. The info of affected drivers and NICs and the resolution can be found here:

              https://support.microsoft.com/en-us/help/2986895/virtual-machines-lose-network-connectivity-when-you-use-broadcom-netxt

              This is a good write-up and how to resolve it. Or you can just run firmware and driver updates.

              VMQ should be disabled on 1 GB NICs. The issue with the broadcoms is that it's enabled by default, and shouldn't be.

                The implementation of VMQ was rolled out so badly.

                I ranted on it in a thread more than a year ago.

                You can disable it on the NICs quite easily.

                  Even if you disable it on the NIC, you may/will still need to disable it on the VM.

                    I have unteamed, and disabled VMQ on the Hyper-V settings. I haven't disabled it on the NIC yet. No change so far.

                    I assume the powershell command will take them offline for a moment... Do I need to have the VM's shut down first before running it?

                      HyperV VMQ setting doesn't matter with 1g NICs.

                        It has mattered with 1 Gbps NICs just more with Broadcom devices.

                          This is provably false. You have said it repeatedly.

                          Yet I have posted clear proof in the previously linked thread.

                            No, what matters is the NIC setting, not the HyperV setting.

                              I know for a fact it doesn't matter with 1G NICs.

                              You are talking about the setting in the NIC properties. I'm not. I'm talking about the setting in the HyperV VM Settings.

                                  Even if it doesn't matter. I have run the powershell command and it's still running slow. Any other ideas?

                                    Is it slow accessing the application via IP and DNS?

                                      The way the app is installed is that essentially all the server is doing is hosting a file share. You place a shortcut to the .exe file on the desktop.

                                        Is the shortcut path and target starts with \\ip-address\... or \\dns\...?

                                          Got it! I have tried both. No noticeable change.

                                            Tried disabling antivirus and maybe firewall on the workstation that is accessing the application?
