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.

Does anyone have any ideas?

Hi,
You could disable SMBv3 on server 2012 to check if the issue related to SMB protocol.

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.

Server 2012 R2 slow performance over all

This is a DELL PowerEdge R820 / 256GB RAM / 4TB onboard storage configured as Remote Desktop Services Host /TS... running QuickBooks, MS Office 2010 STD, Symantec EndPoint Protection (basic antivirus installation ONLY)... 1 month old server... SUPER fast,
super powerfull.... Part of an AD in SBS 2008 Premium... single NIC card 4 ports / 3 ports disabled. single IP... no VLANS... server is able to resolve ANY pc, DNS record with no problems... able to resolve DC by name, able to receive GP, able to update, able
to do everything that I can think of.... EXCEPT... anything I open, word, excel, QuickBooks, IE.... takes forever to open... after the application is open is fast but to open anything takes 3-4 minutes.... open ticket with Symantec all looks good, created
lots of exceptions for antivirus/real time scanning, open ticket with QuickBooks: files look good application was removed and reinstalled to be sure all was done correctly... check the binding order for the disabled NIC; the active one is TOP option, no errors
at all in event viewers for system, application, setup, no errors at all in DELL management tool, no hard drive errors, no controllers errors.... this server is replacing an old dell poweredge 2008 STD with 24GB RAM... the old DELL opens the same applications
way faster than the new one... same Quicken version; old server opens Quicken in seconds, new one 3-4 minutes..... Real time monitoring NEVER goes above 1% for CPU and 3% for memory utilization.... one more thing... removed antivirus 100% restart... same performance
without antivirus.....
Any ideas will be great as of how to troubleshoot the slow performance....
Thank you!

Hi,
Based on your description, I do the same operation in my Lab environment (Hyper-v and Windows Server 2012). Unfortunately, this issue can’t be reappeared. So, before
going further, would you please let me confirm something?
Did you mean that there was no error message when this issue occurred, just the progress was stuck at 24%? How long did you wait for the change approximately? Finally,
can the feature be installed successfully or not?
Meanwhile, please locate to C:\ Windows\ Logs\ CBS folder and check the
CBS log if you can find some clues.
If anything I misunderstand or more details you can provided, please don’t hesitate to let me know.

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!

Windows Server 2012 R2 robocopy not copying inherited directory permission from source file server to destination ?

Can anyone here please help me with Robocopy on Windows Server 2012 R2 to copy the file server content from \\OldFileServer\Data share into the local S:\Data drive ?
here's my script that I use to copy 11 TB of file server contents:
robocopy.exe "\\OLDFILESERVER\Data" S:\Data *.* /E /SECFIX /SEC /XO /ZB /COPYALL /MIR /DCOPY:DAT /R:0 /W:0 /NP /NFL /NDL /TEE /LOG:"G:\robocopy.log"
Any kind of help and assistance would be greatly appreciated.
Thanks
/* Server Support Specialist */

Hi,
Based on my tests, inherited permissions will not be copied using robocopy.exe.
That’s because that after we copy or move an objects to another volume, the object inherits the permissions of its new parent folder.
My suggestion for you is to disable the inheritance on corresponding subfolders, and Convert inherited permissions into explicit permissions on this object. After that, those permissions can be copied.
Here are some references below for you:

Some performance counter objects are not available for a 32-bit process on 64-bit versions of Windows Server 2012 standard

When we try to gather performance counter information for a 32-bit process on a 64-bit computer that is running Microsoft Windows Server 2012, all our performance counter objects are not available with 32 bit perfmon application (C:\Windows\SysWOW64\perfmon.exe)
I didn't notified any errors while registering our counter objects or while running Perfmon.exe
Note: Same counter objects are available and working fine with Windows Server 2008 R2.
for diagnostic our counters on WIN2012, ran command as follows:
cd c:\windows\sysWOW64
lodctr /Q
I am able to see all our counter objects on response and infact all were shown as enabled, as shown below
Appreciate quiclk response with solution or clues to diagnose it more details.
Thanks & Regards,
Sudhakar Rudra

Hi,
Thanks for your reply.
I hope you understood our problem.
same our system counter objects (ver x), we able to browse from Perfmon 32 bit app on Windows 7, Windows 2008 R2 (64bit) OS but not on Windows 2012.
I am able to see all counter objects registered as follows (same at HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\HMI Alarm Class\Performance,
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\HMI Alarm Class\Performance
and
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HMI Alarm Class\Performance)
Only difference I observed that "Disable Performance Counters" were set to 4 in Windows 2012 OS unlike other windows 7 64bit OS and there is no differnece for remaining all entires.
I tried setting that "Disable Performance Counters" value to "0", but some how they get reset to "4", no luck..
I think "Disable Performance Counters" value either "0", or "4", should not matter for browsing our counters with 32bit bit perfmon applicaiton.
Do you see any issues of registry entries. ?
On what basis perfomance monitor list few enabled counters?
How can we add our counters manually to perfomance monitor?

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.

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):

VirtualDisk on Windows Server 2012 R2 Storage Pool stuck in "Warning: In Service" state and all file transfers to and from is awfully slow

Greetings,
I'm having some trouble with my Windows Storage Pool and my VirtualDisk running on a Windows Server 2012 R2 installation. It consists of 8x Western Digital RE-4 2TB drives + 2x Western Digital Black Edition 2TB drives and have been configured in a single-disk
parity setup and the virtual disk is running fixed provisioning (max size) and is formatted with ReFS.
It's been running solid for months besides some awful write-speeds at times, it seems like the write performance running ReFS compared to NTFS is not that good.
I was recommended to add SSD's for journalling in order to boost write-performance. Sadly I seemed to screw up this part, you need to due this through PowerShell and it needs to be done before creating the virtualdisk. I managed to add my SSD to the Storage
Pool and then remove it.
This seem to have caused some awkward issues, I'm not quite sure of why as the virtualdisk is "fixed" so adding the SSD to the Storage Pool shouldn't really do anything, right? But after I did this my virtual disk have been stuck in "Warning:
In Service" and it seems to be stuck? It's been 4-5 days and it's still the same and the performance is currently horrible. Moving 40GB of data off the virtual disk took me about 20 hours or so. Launching files under 1mb of the virtual disk takes several
minutes etc.. It's pretty much useless.
The GUI is not providing any useful information about what's going on. What does "Warning: In Service" actually imply? How am I supposed to know how long this is supposed to take? Running Get-Virtualdisk in PowerShell does not provide any useful
information either. I did try to do a repair through the Server Manager GUI but it goes to about 21% within 2-3 hours but drops back down to 10%. I have had the repair running for days but it wont go past 21% without dropping back down again.
Running repair through PowerShell yields the same results, but if I detach the virtual disk and then try to repair through PowerShell (the GUI wont let me do repair on detached virtual disks) it will just run for a split second and then close.
After doing some "Googeling" I've seen people mentioning that the repair is not able to finish unless I have at least the same amount of free space in the Storage Pool as the largest drive in my Storage Pool is housing so I added a 4TB drive as
due to me running fixed provisioning I had used all the space in the pool but the repair is still not able to go past 21%.
As am running "fixed provisioning" I guess adding a extra drive to the pool doesn't do much difference as it's not available for the virtual disk? So I went ahead and deleted 3 TB of data on the virtual disk so now I've got about 4 TB free space
on the virtual disk so there should be plenty of room for Windows Server 2012 R2 to re-build the parity or whatever it's trying to do but it's still the same, the repair wont move past 21% and the virtual disk is still stuck in "Warning: In Service"
mode and the performance keeps being horrible so taking a backup will take forever at these speeds...
Am I missing something here? All the drives in the pool is working fine. I have verified using various bootable tools so why is this happening and what can I do to get the virtual disk running at full state again? Why doesn't the GUI prompt you with any
kind of usable information?
Best regards, Thomas Andre

Hi,
Please run chkdsk /f /r command on the virtual disk to have a try. In the meantime, run the following commands in PowerShell to share the output.
get-virtualdisk -friendlyname <name> | get-physicaldisk | fl
get-virtualdisk -friendlyname <name> |fl

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.

Hyper-V 2012 High Availability using Windows Server 2012 File Server Storage

Hi Guys,
Need your expertise regarding hyper-v high availability. We setup 2 hyper-v 2012 host in our infra for our domain consolidation project. Unfortunately, we don't have hardware storage that is said to be a requirement that we can use to create a failover cluster
for hyper-v host to implement HA. Here's the setup:
Host1
HP Proliant L380 G7
Windows Server 2012 Std
Hyper-V role, Failover Cluster Manager and File and Storage Services installed
Host2
Dell PowerEdge 2950
Windows Server 2012 Std
Hyper-V role, Failover Cluster Manager and File and Storage Services installed
Storage
Dell PowerEdge 6800
Windows Server 2012 Std
File and Storage Services installed
I'm able to configure the new feature about Shared Nothing Live Migration - i'm able to move VM's back and fort between my hosts without storage. But this is planned and proactive approach. My concern is to have my hyper-v host to become highly available in
the event of system failure. If my host1 dies, the VMs should go/move to host2 and vice versa. In setting this up, i believe i need to enable the failover clustering between my hyper-v hosts which i already did but upon validation, it says "No disks
were found on which to perform cluster validation tests." Is it possible to cluster it using just a regular windows file server? I've read about SMB 3.0 and i've configured it as well i'm able to save VMs on my file server, but i don't think that my hyper-v
hosts are already highly available.
Any feedback and suggestions or recommendation is highly appreciated. Thanks in advance!

Your shared storage is a single point of failure with this scenario so I would not consider the whole setup as a production configuration... Also setup is both slow (all I/O is travelling down the wire to storage server, running VMs from DAS is ages faster)
and expensive (third server + extra Windows license). I would think twice about what you do and either deploy a built-in VM replication technologies (Hyper-V Replica) and apps built-in clustering features that does not require shared storage (SQL Server and
Database Mirroring for example, BTW what workload do you run?) or use some third-party software creating fault tolerant shared storage from DAS or investing into physical shared storage hardware (HA one of course).
Hi VR38DETT,
Thanks for responding. The hosts will cater a domain controller (on each host), Web filtering software (Websense), Anti-Virus (McAfee ePO), WSUS and an Auditserver as of the moment. Is the Hyper-V Replica somewhat give "high availability" to VMs or Hyper-V
hosts? Also, is the cluster required in order to implement it? Haven't tried that but worth a try.

Cannot publish Flash Updates Verification of file signature failed for file SCUP 2011, SCCM 2012 R2 and WSUS all on same Windows Server 2012 machine

I am attempting to distribute Adobe Flash updates using SCUP 2011, SCCM 2012 R2, WSUS ver4 and Windows Server 2012. Everything installs without error. I have acquired a certificate for SCUP signing from the internal Enterprise CA. I have
verified the signing certificate has a 1024 bit key. I have imported the certificate into the server's Trusted Publishers and Trusted Root CA stores for the computer. When I attempt to publish a Flash update with Full content I receive the following
error:
2015-02-13 23:00:48.724 UTC Error Scup2011.21 Publisher.PublishPackage PublishPackage(): Operation Failed with Error: Verification of file signature failed for file:
\\SCCM\UpdateServicesPackages\a2aa8ca4-3b96-4ad2-a508-67a6acbd78a4\3f82680a-9028-4048-ba53-85a4b4acfa12_1.cab
I have redone the certificates three times with no luck. I can import metadata, but any attempt to download content results in the verification error.
TIA

Hi Joyce,
This is embarrassing, I used that very post as my guide when deploying my certificate templates, but failed to change the bit length to 2048. Thank you for being my second set of eyes.
I changed my certificate key bit length to 2048, deleted the old cert from all certificate stores, acquired the a new signing cert, verified the key length was 2048, exported the new cert to pfx and cer files, imported into my Trusted publishers
and Trusted Root Authorities stores, reconfigured SCUP to use the new pfx file, rebooted the server and attempted to re-publish the updates with the following results:
2015-02-16 13:35:44.006 UTC Error Scup2011.4 Publisher.PublishPackage PublishPackage(): Operation Failed with Error: Verification of file signature failed for file:
\\SCCM\UpdateServicesPackages\a2aa8ca4-3b96-4ad2-a508-67a6acbd78a4\3f82680a-9028-4048-ba53-85a4b4acfa12_1.cab.
Is there a chance this content was already created and signed with the old cert, so installing the new cert has no effect? In ConfigMgr software updates I see 4 Flash updates, all marked Metadata Only (because they were originally published as "Automatic."
No Flash updates in the ConfigMgr console are marked as downloaded. I can't find any documentation on how the process of using SCUP for downloading content for an update marked Metadata Only actually works.
Comments and suggestions welcome.

File systems available on Windows Server 2012 R2?

What are the supported file systems in Windows Server 2012 R2? I mean the complete list. I know you can create, read and write on Fat32, NTFS and ReFS. What about non-Microsoft file systems, like EXT4 or HFS+? If I create a VM with a Linux OS, will
I be able to acces the virtual hard disk natively from WS 2012 R2, or will I need a third party tool, like the one from Paragon? If I have a drive formated in EXT4 or HFS+, will I be able to acces it from Windows, without any third party tool? Acces it,
I mean both read and write on them. I know that on the client OS, Windows 8.1, this is not possible natively, this is why I am asking here, I guess it is very possible for the server OS to have build-in support for accesing thoose file systems. If Hyper-V
has been optimised to run not just Windows VMs, but also Linux VMs, it would make sense to me that file systems like thoose from Linux or OS X to be available using a build-in feature. I have tried to mount the vhd from a Linux VM I have created in HyperV,
Windows Explorer could not read the hard drive.

Installed Paragon ExtFS free. With it loaded, tried to mount on Windows Explorer a ext4 formated vhd, created on a Linux Hyper-V vm, it failed, and Paragon ExtFS crashed. Uninstalled Paragon ExtFS. The free version was not supported on WS 2012 R2
by Paragon, if Windows has no build-in support for ext4, this means this free software has not messed around anything in the OS, I guess.
Don't mess with third-party kernel-mode file systems as it's basically begging for troubles: crash inside them will make whole system BSOD and third-party FS are typically buggy... Because a) FS development for Windows is VERY complex and b) there are very
few external adopters so not that many people actually theist them. What you can do however:
1) Spawn an OS with a supported FS inside VM and configure loopback connectivity (even over SMB) with your host. So you'll read and write your volume inside a VM and copy content to / from host.
(I personally use this approach in a reversed direction, my primary OS is MacOS X but I read/write NTFS-formatted disks from inside a Windows 7 VM I run on VMware Fusion)
2) Use user-mode file system explorer (see sample links below, I'm NOT affiliated with that companie). So you'll copy content from the volume as it would be some sort of a shell extension.
Crashes in 1) and 2) would not touch your whole OS stability.

Ext2Read

(both are user-land applications for HFS(+) and EXT2/3/4 accordingly)
Hope this helped :)
