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

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.
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.

OH, I know...just enjoyed his perspective. At least I don't have to pull his long hours and sometimes crazy on-call schedules.

I did turn off VMQ on the Physical Adapters and bam! Normal Speeds!
In fact, then testing one of our apps, making it's work directory a folder on the VM, I got a 3 second increase compared to physical drives on our current server and the hypervisor...finally, some success! LOL -

When I rolled out a server in November, yes this was the case. I have not read up about any changes as I have no Hyper-V installs pending. I will state, that I did attempt to install to the built in RAID1 SD in the Dell server then and that failed. That led to my searching which stated that it was not possible except for a limited OEM version that was not published.

Okay. So now for backups.
In what way is Unitrends appearing to not be the right solution? What is it lacking in the free version?

It's hard to tell context in a message (saying I am not irrationally upset...I'm content but determined...LOL) but I am done with virtualization. Every time I try something, some new challenge comes up. I just want the new server to work as the old one but faster. I've got too many other duties piling up (like ordering toner for our copier, LOL) and I've spent a week on this and keep finding roadblocks. I am getting great advice but it doesn't seem to be good for our environment or budget.

Not throwing in the towel but serious, one man IT shop and too much to do right now to keep encountering these little roadblocks and detours. Basically, I need a all in one backup suite to backup AD, Files, SQL on both virtual and physical. With ZERO budget. I guess I could use BOTH programs but I like it nice and neat.
-
Okay. Just one final question then. Now that you have things working on HyperV - if you want to do everything the same as before, why does that rule out virtualization? Can't you do everything the same and virtualize?
No need to do anything differently because you are virtualizing. Aren't all of the roadblocks, other than the temporary performance one, caused by looking to make other changes and not because of the virtualization at all? Or did I miss some roadblock that has come from the virtualization.
-
And by that I mean keeping the BackupAssist, all roles on one server, static IPs, everything. If you skip virtualizing today you are locked in for the life of the system. You give up your options.
But as long as you virtualized now, everything else can stay the same and/or change gradually over time. Only this one piece is a cut and dry do now or miss out for a long time.
I don't want this to seem overwhelming because of lots of moving parts. But I don't want you screwed for years to come either.
-
To bad you don't have more time to work/play with this.
First things first - @scottalanmiller is right - you should ditch HyperV only because you don't have the time to learn how to make it work correctly. VMWare ESXi Hypervisor (free version) is super simple to install - insert CD and install. it's pretty much nearly that simple.
Even if you stay with HyperV now that you have performance issue resolved you're 80% there.
As Scott mentioned, the processes you have to follow to move to a new server are the same on VM or physical server.

I would generally wait until after hours but should be pretty safe in most environments. AD is rarely something that an SMB depends on minute to minute.
Tempting to do now...but I can VPN around 5:30 and run it too.
I tried running ADPREP and it didn't work since my current Domain Controller is 32 bit. So if I understand this article correct:
http://support.microsoft.com/kb/2743367
It has to be run remotely? It was kind of vague.
Correct - you have to run the commands on a 64bit system (most likely your newly installed 2012 R2 server)
-
The ADPrep issues will follow you to a physical environment too.
