      Good idea. You will feel much better.

      Start with DHCP. Start rolling that out tomorrow.

            Here's the slowness I've been talking about in my VM2 (File Server called services01)

            This is only a 82 MEG file...taking FOREVER to copy to the drive on VM2:

            ![copySlow.jpg](uploading 100%)

                Looks like picture didn't attach well...basically showing 25 minutes to copy just 82 meg from my PC to the drive on VM2, that will eventually be our main file server drive. In addition, task manager shows 89% memory usage (of the 4GB allocated and on dynamic)...about to reboot the VM2 and see what happens but this is scary.

                  @garak0410 look at the tcp offload settings. I am not at a place to look at the client where I had the same problem. but there is a setting in hyper-v manager that I had to change then reboot everything in order get get the network to perform correctly.

                    image button uploads images to imgur. If you know the link you can edit the post to do it manually.
                    remove the extra whitespace I added to make it show

                      So I should turn off the TCP Checksum offload for IPv4 on both virtual adapters?

                        This is where installing to USB is recommended. Just have a spare USB copy laying around.

                        Except you cannot install Server 2012 + Hyper-V to a USB.

                          Just logged into that server. It was VMQ that I had to disable. I think it was on by default and I never checked if it was supported or not. The users were screaming down my back so I just disabled it.

                            OK I'll check that because turning off TCP Checksum offload for IPv4 has no effect and was even show to delete files from that drive...took 3 minutes to delete 10 meg...

                              Is turning off VMQ a command line or a GUI option? Not seeing it.

                                Are you sure? Microsoft just recommended that two weeks ago on SW.

                                  Well, something is causing extreme slowness just copying a file from my PC to the drive on my VM2 (services01). Horrendous. Is it network or VDISK related? I have a week now but got to get this resolved right away.

                                    Honestly just install ESXi or XenServer. They aren't all weird and picky like HyperV.

                                      You may be right...and may be crazy! LOL...I had a network engineer tell me last night to just say physical in my environment...love the varied opinions I get. 🙂

                                        A network engineer isn't a discipline that would know anything about this nor understand the ramifications.

                                          HyperV is the hardest to use and biggest learning curve. Install XenServer and see if that just fixes everything for you.
