Windows server 2012 R2 Slow RDP

Hi
I have server 2012 R2 Datacenter installed on HP Proliant 380 G8. All drivers and firmwares are updated and confirmed by HP. The machine is quite powerful with hundreds of gigs of RAM.
When I RDP into the machine, The screen hangs on "welcome" screen for a good 10 seconds. Same hardware with server 2012 Datacenter is much faster. It is also fast with 2008 R2.
I deployed 4 servers so far and all have the same issue.
Has any one experienced this slowness before?
I appreciate any help.
Thanks

Hi Atif,
Thank you for your posting in Windows Server Forum.
First of all please try to provide TP’s answer. In addition, what’s the version of client OS and RDC? If you are using Windows 7 then use RDP 8.1 for better performance. Apart from this, try to DisableTaskOffload in the IP-parameters. For more information,
kindly go through beneath article.
Performance Tuning Windows 2012: Network Subsystem–Part 1
Also try to configure below setting, might helpful for your case.
On the server:
Computer Config > Windows Settings > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Connections > Select RDP transport protocol = Use only TCP
On the client:
Computer Config > Windows Settings > Admin Templates > Windows Components > Remote Desktop Services > Remote Desktop Connection Client > Turn off UDP on Client = Enabled
Hope it helps!
Thanks,
Dharmesh

Windows Server 2012 very slow performance executing files

Hello,
I am running windows server 2012 as dc with 2 clients connected running win7 pro x64, this is a new setup.
Whenever i try to open a large file from the client or an application from the client it takes forever to startup or to load. The performance monitor indicates a maximum workload of 15% at all times.
I have tried all the following potential solutions i found, however none of them seem to do the trick.

Windows server 2012 standard - slow performance in file sharing

I recently installed two windows server 2012, one is for DC, one is for File Sharing; it works fine in the beginning.
Lately, it comes a problem, every once a while it is very slow when opening a file on the server from a client PC; but when i restart the file server then it will be fine again.

Hi Simon,
Based on your description, how is the workload of the file server?
Before going further, regarding slow network performance when opening a file that is located in a shared folder on a remote network computer, the following article can be
referred to as reference.

Fresh install Windows Server 2012 R2 cannot RDP

I did a fresh install of WS 2012 R2. I enabled remote access as normal leaving network authentication on. I am unable to rdp to an administrator desktop. I then enabled pinging of the new server to make sure I can see the server. I am able to ping the server
from the WS I wish to RDP from and to ping the WS from the server.
I have installed a lot of servers and never had an issue with this.
Anything new in R2 which I'm missing?

Figured it out! Trying to RDP from outside domain, R2 has this rule disabled in Firewall.

Serial Port communication very slow in RDP on windows server 2012

Hellò, we have installed a new server 2012 and connected some thinclients via RDP, since that moment all peripherals connected to the imported com ports of the thinclients are running very slow, for example the cash register issue any receipt only after
15-20 seconds!!. We have try to connect via RDP also a personal computer with many other OS like windows 8, windows 7, or XP but the result is the same: 15-20 seconds for a receipt!! We solve the problem only changing the server 2012 with a old server
2008 or 2003!. How is possible window server 2012 is so slow on RDP imported com ports??. There is something to set for speed up the com ports on rdp? For us this is a great problem, all of our customers are using cash register via RDP and they can't wait
all this time for a receipt. For your information we have tried to connect the cash register to the same com port of the same thinclient to the same server 2012 without RDP and the issue of the receipt is fast, so the problem is something on RDC of the new
OS windows Server 2012. Also note this is a bi-directional communication because the cash register use a bi-directional communication for printing each one of the voice on the receipt, this problem wll not affect other printers unidirectional where the
print process starting in less one second. Please help us to solve this problem, otherwise we will not more install windows server 2012.

Hi,
Thanks for your posting in Windows Server Forum.
When the slow performance issue occurs on server 2012, check the Windows Logs – Application category of the Event Viewer (eventvwr.msc) on both the client and server sides. If there is any logs recorded, please let us know them. Please also check the
driver is properly installed on server and check the compability guide with the cash register machine, whether it support server 2012 with remote session. If there is particular requirement then you need to solve them first.
In addition, would like you to try connecting with RDP 8.1 and check whether it faces same issue.

Disabling RDP Compression on Windows Server 2012 R2

Hi
On Windows 2008 R2, we could disable RDP compression via GPO by configuring "Do not use an RDP compression algorithm" in the following GPO
Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Set compression algorithm for RDP data
It seems like with the Windows Server 2012 R2 GPO's, this setting is no longer available? How do we disable RDP compression so that we can use it with Riverbed products?
Thanks

Hi,
How is the issue going now? Is there any update?

Windows Domain Controller on Windows Server 2012 R2: Hyper-V roaming profiles not loading due to slow connection

I have racked my brain and done everything that I know to do for about two weeks now. I am setting up a new system at our fire department and I am having the worst luck with getting the workstations to login to the domain controller with roaming
profiles. It keeps telling me that the roaming profile could not be loaded because of a slow connection. These are workstations that are connected directly to the switch that the DC is connected to. I have tried multiple connections regarding
the layout (DC into the router, router into the switch). The router is a Cisco RV220W. I have two VLANS, one for public and one for private domain. The Private VLAN has DHCP turned off since I am providing it through the DC. I currently
have a connection from the Private VLAN going to the unmanaged switch that the workstations and server are plugged into.
The server is a Dell PowerEdge R420 that has 6 NIC ports (1 dual port and 1 quad port). I have a virtual switch setup on Hyper-V for an external port (let's say Card 2 Port 3) that is assigned to the WS 2012R2 Domain Controller. The DC can see
the internet fine and the workstations can connect to the shared folders on the server. I can retrieve files by just using the computer name or FQDN. The DC is also running DNS and DHCP. The DNS has the _msdcs setup from when I installed
the active directory role. I have attempted to assign static IP addresses to the workstations:
IP:                     10.0.0.80
Subnet:             255.255.255.0
IPV4 Gateway: 10.0.0.1
IPV4 DNS:        10.0.0.12
I've attempted "append the specific DNS suffix", I've "registered the connection in DNS", I've used "use this connections suffix in DNS registration".
The server is assigned:
IP:                     10.0.0.12
Subnet:             255.255.255.0
IPV4 Gateway: 10.0.0.1
IPV4 DNS:         10.0.0.12
The DNS entries have forwarders that forward to my ISP DNS servers for lookup
I've enabled and disabled DHCP, I've installed a new VM just to create another DC to make sure that I didn't goof up when I created it.
I've lost my patience with this project and am sinking fast. Can someone please offer some advice as to what I've done wrong? I've created this exact scenario at work many times but, I've never done it with Windows Server 2012. Is this
possibly something to do with the Dell PowerEdge server (Generation 12) with the SR-IOV? I am going to attempt to work on it some more tomorrow when I get over there. I think there may be an issue with the SR-IOV not being enabled on the machine
through the Dell Bios. Would the SR-IOV really cause the workstations to report a slow connection? When I login at the domain controller the roaming profiles and folder redirection work fine so, I know the GPO settings are correct. I don't
have "ignore slow connections" or any of those GPO's set. I need to get it working the correct way so, I didn't want to fool the server when there is another underlying problem. Any help that someone can offer, I am more than willing
to listen. If you need more information, please ask.
Thanks,
Jay

So, I've managed to research this some more since Thursday and I've come to the conclusion that Hyper-V does a horrible job of supporting Qualcomm NIC cards. That's the only thing I can conclude as far as where the issue is originating. I've read many
post and walkthroughs but nothing that has helped. The issue wasn't with any settings in the domain controller. The issue was that there really is a slow connection originating at the domain controller that is a VM and has network connectivity through the
virtual switch from Hyper-V. So, next question is, how do I get the DC to have better connectivity through the NIC that Hyper-V won't give it? If hyper-v would allow passthrough, this would be so much simpler. VM-ware is looking really good at this point.
Im disappointed in MS right now.

Windows Server 2012 Storage Spaces Simple RAID 0 VERY SLOW reads, but fast writes with LSI 9207-8e SAS JBOD HBA Controller

Has anyone else seen Windows Server 2012 Storage Spaces with a Simple RAID 0 (also happens with Mirrored RAID 1 and Parity RAID 5) virtual disk exhibiting extremely slow read speed of 5Mb/sec, yet write performance is normal at 650Mb/sec in RAID 0?
Windows Server 2012 Standard
Intel i7 CPU and Motherboard
LSI 9207-8e 6Gb SAS JBOD Controller with latest firmware/BIOS and Windows driver.
(4) Hitachi 4TB 6Gb SATA Enterprise Hard Disk Drives HUS724040ALE640
(4) Hitachi 4TB 6Gb SATA Desktop Hard Disk Drives HDS724040ALE640
Hitachi drives are directly connected to LSI 9207-8e using a 2-meter SAS SFF-8088 to eSATA cable to six-inch eSATA/SATA adapter.
The Enterprise drives are on LSI's compatibility list. The Desktop drives are not, but regardless, both drive models are affected by the problem.
Interestingly, this entire configuration but with two SIIG eSATA 2-Port adapters instead of the LSI 9207-8e, works perfectly with both reads and writes at 670Mb/sec.
I thought SAS was going to be a sure bet for expanding beyond the capacity of port limited eSATA adapters, but after a week of frustration and spending over $5,000.00 on drives, controllers and cabling, it's time to ask for help!
Any similar experiences or solutions?

1) Yes, being slow either on reads or on writes is a quite common situation for storage spaces. See references (with some of the solutions I hope):

How to install RDP CALs pack on Windows Server 2012 R2 (member of NT domain)

OS: Windows Server 2012R2 (64-bit), member of NT (Samba 3) domain.
Task: install RDP CAL pack, to allow connecting above its default 3 sessions limit.
Problem: when setting up RDP licensing/other required service, I came to a problem: RDP access broker service requires AD type of domain to be installed.
The server is part of NT (Samba 3) domain and we have no intention to change domain type only to satisfy an auxiliary service.
Is it possible to enable additional RDP CALs on Windows Server 2012 R2 without mandatory joining an AD? The license control available up to Windows Server 2008 has been removed from Windows Server 2012, I can't bypass installing broker and the rest of related
services.
Thank you for any information.

Single server solution for RDS / TS / RDP using Windows Server 2012 R2

Planning on setting up a small single server and need this functionality:
* 3 local users runnnig Windows 7 Home Premium needs to access files on the server
* The same 3 users should also be able to connect from home (PC, Mac, iPhone) and run an application on the server. (Session-Based Remote Desktop).
We want to use Windows Server 2012, and found out that Essentials does not support RDP, so that leaves Foundation and Standard versions.
However, I also found out that in WS 2012 the RDP can not be on the same server as the Domain Controller, and we therefor needs to run 2 server instances on our hardware. I think this starts to look way to complicated for what we want to do, but found out
that WS 2012 R2 allows a single server to run RDP (See TechNet article 2833839).
So we will go for Windows Server 2012 R2, either Foundation or Standard to set up our RDP.
So now the question: Will that solution work with our local machines running Windows 7 Home Premium, as they cannot connect to a domain? Can we set up some kind of simple file share or Workgroup to acces files locally while still keeping the RDP
functionality on the server?
And, will WS 2012 Foundation R2 do this as well as WS 2012 Standard R2?
(I have been asking several locat MS representatives to find a solution to our needs, but no one seems to know how this works....of cause we could just get 2 WS 2012 Standard server instances, run one as DC and on as RDCB and upgrade all our clients to Win
7 Pro, but we would like a solution with minimal investment in time and money)

Hi Ryan,
and thanks for the answer! I do not know how to do "multiple quote" in this forum so I do it this way:
"have you considered virtualisation, as you can run multiple virtual machines under one licence. I think this would be the cheapest and most efficient use of your money. Upgrading your clients to Windows 7 pro would allow you to have domain control
Single Sign On SSO. "
This is the "official" solution I think: Upgrade all clients to Win 7 Pro and run two instances of Win Server 2012 Standard on the server.
However, I was hoping to get away with something a bit more Quick & Dirty.....;-) We do not have big security issues and will have a good backup system, and I think for 3 users only, it will be more work trying to centralise administration like updating,
backups etc, than to just go to each machine and do what is needed.
We are good with computers/Windows but have no Server experience. A server guy will help us get started, but I dont want him around after that, so it must be a very simple solution.
Also, installing 2 instances of WS 2012 and upgrading all 3 clients to Win Pro, and then installing all software and settings on the clients into the new domain user accounts on these clients is quite a lot of work. So I was hoping to keep only existing local
users on the client machines and only have some kind of file share thing going on with the server disks that we need to access. So perhaps use a Workgroup instead of a domain, if that works with the RDS setup?
"Option 1
2 virtual machines 1x DC and 1x RDS server."
So, if we set up RDS this way (so we can log in remote and run our application session-based on the server), can we keep the local clients running Windows Home Premium using our current local user logins (ie no domain user accounts created on the client machines,
as this is impossible in Home versions) and still access the server disks somehow, or is it impossible?
Another question is if it is stupid/a really bad solution...but I still want to know if it is possible....;-)
"Option 2
2 virtual machines 1x DC and 1x RDS server.
You can configure your RDS solution as a domain joined platform and will still be able to access resources from the local device as you can map local drives to the session host. http://www.serverintellect.com/support/techfaq/drive-rdp/
Your users would have two sets of credentials, one for the local client and one for the domain."
I do not want to access files over VPN or RDP, we only want to run an application on the server from remote (Session-Based Remote Desktop). However when we use the local clients we want to access files on the server, and then we access huge image and film files
on fast RAID drives, so local network speed must be top speed. Also if possible we would like to not upgrade to Win Pro, and then joining a domain is not possible.
"Option 3
1x Server
The second option would be to manually deploy the session host role and licencing role to a work group server. This would limit access to RDP only and you would loose web access functionality."
I think this is what I was hoping for. It seems that the new R2 release of WS 2012 allows you to rund RDP and Domain Controller roles on the SAME instance of the server. That sounds nice, it limits what we need to keep track on and minimises the load on the
server that needs to act as a very fast file server locally.
However, can we do this and still keep file acces with only Windows Home (no domain) in the local clients (same question as above under "Option 1")?

Windows Server 2012 HyperV VMs becoming extremely sluggish and slow

I have recently set up a new system for a client consisting of a single Dell T320 server with Xeon E5-2350 2.2GHz 6 core cPU and 32GB of RAM. Windows Server 2012 Standard is installed on the bare metal, and runs only the HyperV role. It is not
joined to any domains.
It hosts two VMs, one a Windows Server 2012 Standard VM containing the RDS related roles acting as remote desktop server, with 10GB RAM allocated and 3 cores. Only 5 people use the terminal server concurrently.
The second VM is a Windows Server 2008 R2 based primary domain controller, with 16GB of RAM allocated and 3 cores. It runs the AD role, as well as Exchange and GFI MailEssentials 2012. Avira is also installed on this VM.
The problem is that the system will function properly for 3-4 days, then suddenly it goes into a state where a multitude of applications would start consuming inordinate amount of CPU time, and become very, very slow. Almost like the hypervisor goes
into a software emulation mode where everything runs like molasses. This affects BOTH VMs equally. For example, Exchange and GFI on the Windows 2008 R2 VM together consume about 25% CPU, most of it is spent in kernel CPU time. At the same
time, in the other Windows Server 2012 VM, svchost, Taskmgr, WMIPrvSE, LogonUI, Explorer, sqlservr, wsmprovhost etc. will all consume a total of about 70% CPU time, this time 99% of this is user time, not kernel time. When one user starts any application,
be that internet explorer, firefox or TaxPrep, the CPU spikes up to 100%.
All while nobody is using the system, the system is idle and no mails are flowing in or out of the system. A reboot of the VMs does not fix anything, even a reboot of the host server does not fix anything. When I yanked out the two power supplies
and performed a hardware diagnostic (which came back 100% OK), it booted up and the slowness was gone for 3 days, until today when it started acting up again like I described above.
One more thing, when the system behaves normally the sunspider javascript benchmark in IE10 takes 316ms to execute (average) on the HyperV host operating system. When the system goes slow like this, I pause the two VMs in HyperV then run sunspider
again, only to be greeted by an average time of 5084ms. So this clearly does not only affect the virtual machines but the host operating system as well. My gut still tells me the hypervisor is getting messed up somehow.
Any ideas? This is a major problem and I have no idea what is causing it.

We have had the EXACT same thing happen with a Dell T320 on two separate servers. The first one was running SQL Server 2008 with nothing else funny going on. It ran fine for a month or so, then it developed this slowness issue. We finally installed SQL on
a loaner box (without Hyper-V) and it worked fine. We brought the T320 back to our shop and tested the hell out of it with Dell's assistance and it was NTF. Took it back onsite and moved an SBS 2011 VM over to it. After a few days, it ground to a halt. CPU
utilization was 100%. I started shedding services, killing Exchange, Sharepoint, etc. Even stripped to the essentials, the CPU was still up in the 60-70% range.
I put a T310 out onsite and downed the guest SBS vm. I copied the HUGE vhd over to the T310 (running Server 2008r2 with the Hyper-V role) and it ran perfectly. CPU at about 2-4%, spiking to 15% occasionally.
We finally concocted a story that the USB controller was bad, so they replaced the motherboard (not the CPUs) and it all seems to be working OK now after we sunk at least 100 man-hours into the problem.
Our second one is a similar setup. T320, Server 2012, Hyper-V role, SBS 2011 Standard and a couple of member servers running basic apps. No one can find any problem and everyone acts like this is something new, although my posting comes one year after Tim's
original posting.

Windows server 2012 R2 PXE boot is unworkable slow, I have this exact same set-up working in 2008 R2 What can I do?

Hi there
I'm trying to deploy a windows 7 image through Windows deployment services via PXE boot from a 2012 R2 server.
Issue: PXE boot is extremely slow, it takes up to more than 60 minutes for the device to download download the PXE boot
Things I already tried to get this up and running:
I've tried to change the TFTP block size via command prompt and via regedit
I've changed the settings on the tab of the WDS role (go to WDS role -> properties on server -> Tab "tftp")
Both actions resulted in PXE boot being even slower than it already was.
To make sure this is not because of our environment I’ve set up the same configuration on a windows server 2008 R2, here PXE boot image is downloaded to the machine within 3 minutes.
Both servers are set up through Hyper-V this is the configuration:
2008 R2:
Memory: 4096 MB
1 Virtual processor
IDE controller 2 hard drives
Network adapter
2012 R2:
Memory: 4096 MB
32 virtual processors
SCSI controller 2 hard drives
Network adapter
I can’t imagine that PXE boot is not working because of the differences of the Hard drives controllers or because of the amount of the virtual processors.
Windows server 2012 R2 seems to handle PXE boot TFTP differently in comparison to 2008 R2.
Do you guys know what I can do/try to get this working?

Hi Jacques Rodrigues,
You can run Windows Deployment Services on Hyper-V virtual machines,
that the performance will often be degraded, particularly during the Trivial File Transfer Protocol (TFTP) download phase. This phase is very resource-intensive and may
fail if insufficient resources are available on your server running Hyper-V.
If you are using multicast, Check if IGMP Snooping is enabled i.e. Routers that support multicasting. In particular, Internet Group Membership Protocol (IGMP) snooping should
be enabled on all devices. This will cause your network hardware to forward multicast packets only to those devices that are requesting data. If IGMP snooping is turned off, multicast packets are treated as broadcast packets, and will be sent to every device
in the subnet.

Black Screen on a RDP Session on a Windows 8 VM (with a RemoteFX 3D Card) running on Windows Server 2012 HyperV

Hi,
I am trying to test a Windows 8 VM (RTM) with a RemoteFX 3D adapter (I used Powershell command to add the RemoteFX adapter to the VM) and when I connect the machine with the RDP Client (Windows Server 2012 RTM),
I just get a black screen.
Off course, I can not connect using VM Connect (because RemoteFX is enable in the VM).
I tested same configuration but this time with a Windows 7 VM and this time it's OK, RemoteFX working fine.
Any Idea will be apreciated :-)

I may have a solution for this which I am about to test.
My environment is 2012R2, Win8.1 VDI Machines on a Dell R720 with Nvidia GRID K2.
I've been trying to rollout VDI all week with everything working except RemoteFX.
On logon the screen is just black but if you press enter it continues to log on, it appears that the logon message text may be causing the issue so I have created a GPO for my template machines and client machines which disables require CTRL+ALT+DEL
and also deletes from the registry the logon message and logon text entries that are displayed on all machines, I figure the users will see this when logging onto their ThinPC machine before connecting to VDI so it's not needed twice.
CONFIRMED working!!

1. How to RDP my windows server 2012 from my Windows 7 with " Firewall disabled" & "Firewall Enabled" conditions

Hi,
Just make sure that the firewall is disabled in all three profiles Domain/Private/Public.
Create a incoming UDP rule on firewall to allow port 3389 and give a try.
