Windows NLB Issues in VMware environment

Hi there,
We are planning to use Windows NLB cluster for high availability solution, and found several blog post in Vmware stating the issues of Windows NLB and unicast network configurations.
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1006580
I am not sure whether the above issue is only with WS2003 OS or also exist in the WS2012/WS2012 R2 operating system as well.
Any help is appreciated.
Thanks,
Vineeth

Hi Vineethk,
Could you clarify your question what issue you have meet, the Windows NLB still use the unicast and multicast, but the NLB on VMware need some VMware product configuration,
you can refer the following VMware solution to solve your issue.

Best solution for Windows gaming in OS X environment

Hello!
What would be the best solution to play Windows games in OX X environment - Parallels or VMWare? (iMac 2012)
I do know that is would be best for performace just to make a separate installation of Windows via BootCamp, but I need to run Windows in OS X environment only.
I just obtained a custom-built iMac with 680MX onboard and would like to switch to Mac completely from my PC. But gaming is one of the most important aspect of my compure use. So I would like to have the ability to play as I did on PC without constant annoying reloading of the machine.

Wine is going to give you better performance over any VM for games. It supports a great deal of DirectX 9 games and DirectX 10 support is planned for the coming months.
Give Barrel a try (http://barrelapp.co.uk). It's an app I developed that lets you install, run and manage windows games on OS X 10.7+ by using Wine, that was designed with usability I mind. If you try it and have any questions ask and I'll answer them.
Alternatives are wineskin and crossover for Mac.

Enterprise DNS servers are not responding when using Windows NLB with Direct Access 2012

Hi
We have installed Direct Access 2012 as one server installation:
- Two network cards. First one in DMZ and second one in internal network
- Two consecutive IP addresses configured in DMZ because of Teredo
- PKI because of Win7 Clients IPSec
- Our corporate network is native IPv4 so we use DNS64/NAT64 and DA-server is configured as DNS
- DA-servers are VMWare virtual machines
One server installation works fine and now we want to use Windows NLB as load balancing. NLB installation goes fine too,
but problem is DNS. If we still try to use DA-server as DNS there comes error message below
None of the enterprise DNS servers 2002:xxxx:xxxx:3333::1 used by DirectAccess clients for name resolution are responding. This might affect DirectAccess client connectivity to corporate resources.
When trying to configure DNS using Infrastructure access setup, DNS cannot be validated when using DA-servers DIP or cluster VIP. Only domain local DNS looks to be ok but those have no IPv6 addressess. So how DNS should be configured when using multicast
NLB?
Tried to remove name suffix then adding again => Detect DNS server => DA-server IPv6 address found => validate => The specified DNS server is not responding...
Then tried to ping detected address => General failure
NLB clusters are configured as multicast and static ARPs are configured too. Both clusters can be connected from those subnets as they should be.
Any clues how to fix this?

Windows NLB for SPF high availability

I have SPF in my organization as a bridge between VMM and WAP. One of my design tenants is to configure everything in a high availability configuration and I am having trouble getting SPF to work in an HA environment.
If I set the binding on SPFs website to the NLB name and use the certificate that I have for it, WAP is unable to write anything to the SPF database. If I set SPF back to no binding and use the certificate that is created for the machine itself, WAP
works exactly as it should.
The NLB that I am using is windows NLB and I have it configured in unicast /w all ports being forwarded to the SPF server. I have just one NIC per server on my SPF instance.
I understand that SPF is supported and have configured it using this guide... (link: http://www.hyper-v.nu/archives/mvaneijk/2013/06/system-center-2012-sp1-service-provider-foundation-high-availability/) It works from the server to the VMM server (using
the web test as prescribed) but gets an error 12 that references the provider section of the site when I try to create the SPF connection from WAP.
Does anybody have any ideas?

thank you for the prompt reply. The certificates that I am using are created by my enterprise CA which is automatically trusted by my WAP servers. The servers all get a client/server authentication certificate as part of AD's auto-enrollment.
I have created a custom certificate with just the name of the NLB. Do i need to specify the actual server names of the SPF environment as SAN's in the certificate request? Could that be the problem?
Single server SPF uses a certificate that is trusted with the single server name
NLB environment uses a custom request certificate that has client/server EKU and the only name that is registered is the DNS name of the NLB's IP address. This is the same name that I put in the binding for the spf website on my SPF servers.
(this method is broken)

Nishant,
Sorry for the late reply. You may well have resolved this by now, if you have can I suggest that you update the post with the resolution so others may benefit.
Looking at the logs, I can see that Jabber is trying to login to the IMP server below, but its returning server unreachable error.

I can't eject ("files in use by another application") Windows/Vista Issue?

OK... so in the grand scheme of things, this really is NOT the end of the world... but it sure is super-annoying!! This is my first every Apple product (took a while to get on the bandwagon) and I was hoping for more stability and ease of use... I've called AppleCare several times and they can't help me figure this out... according to them it's a Windows/Vista issue (which DOES seem likely). I'm running Windows Vista Home Premium on a Dell Dimension E521.
Here's how it goes... I plug my iPod in, which opens up iTunes and it syncs fine. I wait until the top of iTunes says "sync complete" and the face of the iPod simply says "Connected". Then I click on the "eject" button next to the iPod listing in iTunes. It pauses for a moment, then I look down and the iPod suddenly has those syncing, circular arrows, moving again and it says "Synchronizing- do not disconnect". And then a few moments later, iTunes gives me a pop-up that says " XXXX ipod cannot be ejected because it contains files that are in use by another application"
So obviously, something else is connecting to the iPod and preventing me from ejecting it using iTunes, but I have not been able to figure out what it is!
Since it's something on my machine, I have tried the following:
- shut down AntiVirus (TrendMicro Internet Security 2008)
- turned off Windows Firewall
- went through all the programs running in the task bar and turned them off
- opened up Task Manager and turned EVERYTHING else I could see off
None of the above have made any difference. The workaround that Apple gave me was to go into Computer and then right click on the listed drive and select "Safely Remove" which usually works (the times it doesn't work, it gives a similar message saying the device was being used by another application and can't be removed, try again later). But 90% of the time it works.
I use that or the Eject option when I right click on that drive (not sure the difference, they seem to do the same thing). The workaround works, but I'd sure LOVE to get iTunes to be able to eject my iPod!!
Here's what I've done regarding this iPod and iTunes:
- reset the iPod
- restored the iPod
- uninstalled and re-installed iTunes
- selected and unselected the various things I'm syncing (currently: Music, TV Shows, Podcasts, Photos) to see if it was one of them causing the issue
NONE of the above has made any difference (and I've done each about 2-3 times, ZERO exaggeration).
I've called into AppleCare about half a dozen times now, hoping to get that one brilliant tech that knows more than the others... but no luck yet... so I thought I'd try this forum to see if one of the brilliant posters here can help me sort this out.
PLEASE- ANY help you can provide (or even just point me in the "right" direction of how to determine this) would be GREATLY appreciated!!
Thanks so much in advance,
SC

I am using windows Vista and having this problem also (not exactly, but iTunes gives pop-up that "files are in use"). Acting a suggestion from another answer in this thread, I clicked on Computer and selected eject...windows did warn me that the device was in use, but also gave me a CONTINUE button, which I clicked and it was ejected...had to go back to iTunes and eject the iPod there also, but it did eject

We have a 10 person office - all either use Acrobat XI or Reader XI. One person is on Windows 7. The rest are on Windows 8 (not 8.1). I say this because I thought it was a Windows 8 issue, but having the same problems on the Windows 7 machine. We are all having problems opening pdf's sent to us from other firms. This has increased in frequency over the past two months. We've checked with the various firms, and their other clients are not having problems. Some pdfs open but with a lot of missing content and strange formatting, others won't open at all. There are different error messaged depending upon the doc. Some are regarding the fonts, for example "can't extract the embedded font...." Others are "insufficient data" errors. There are more, but for purposes of keeping this short, I won't include them. Another unrelated issue is that we are having trouble printing excel files to pdf. The files end up with bad formatting. I've worked with adobe "chat" support, our IT consultants with no resolution. I also haven't found any similar "known issue" online Would very much appreciate any assistance. Thank you

The font embedding can be a problem if not done and you are trying to view the PDF and do not have the font on your machine. Acrobat will often try to find a replacement, but it is not always a good choice. Sometimes the "Use Local Fonts" button can be changed in state to resolve some of the viewing issues.
If you are trying to copy or export info, then it is important that you have the fonts on your system. Otherwise, the message you are getting about embedded fonts would not be showing up.
As for Excel formatting, be sure that the Adobe PDF printer is selected in the printer screen before you look for the paging and formatting of the file. In most OFFICE programs, if you change the printer the application will reflow the document to best match the printer (called "using printer metrics"). So check before you create the PDF that the layout is correct.

Windows 8 Issues

So, I have purchased 'Windows 8 Pro' and am working to get it stable on my W520.
Specs:
- Lenovo W520 4270-CTO
- i7 2720qm
- Quadro 2000m
- 16gb G-Skill DDR3
- 120gb Intel 320 SSD
Usage:
- Systems Engineer using various development suites, virtualization technologies (directed i/o is a must), and other processor/ram intensive activities. I am looking to use Hyper-V and do some fairly heavy infrastructure simulations.
- Occasional games (usually DOTA, Skyrim, etc.) which run at high FPS with gfx settings near maxed (Starcraft 2 is an exception, which doesn't work at all... Stupid Blizzard...)
Windows 8 Issues:
- Cannot boot off install media with VT-d Virtualization Technology enabled. If I re-enable it post-install, sometimes it crashes, sometimes it doesn't.
- Blue screens on sleep resume
- Crashes on various driver installs (random, sometimes they work, sometimes they don't), locks up on boot, then after physical restart, crashes on Automatic Repair before being able to start back up normally.
- After installing Hyper-V, system crashes, crashes on automatic repair, then is AOK...until it randomly crashes
What I've Tried:
- Switching between Integrated/Discrete/Optimus graphics doesn't seem to have made any difference.
- Disabling VT-d seems to have helped with issues booting, but alas, no big fixes
- Updated BIOS to 1.38, and 1.39 - both made no difference, still at 1.39.
- Event log reports kernal power loss and various bugcheck errors but unable to find anything referencing the code provided, nor is there any surefire reported dll or driver which seems to be sticking out.
- I have attempted 3-4 installs from scratch without resolve.
Other then these issues, if its booted and doesn't crash, the o/s is quite peppy (faster then w7 by a fair degree) and the UltraNav touchpad works quite well with navigating Metro and various Charms.
Have a Mini Series 3 dock which works well (although it has its issues i'll post up elsewhere) and switches between docked and normal usage with ease.
I have since reverted back to Windows 7 until I can find something promising to work with as the lack of support resources is understandably limited at this point.
I cannot develop for Windows 8 or Windows Phone 8 without upgrading or buying a new system. I've been quite happy with my W520 but this is just frustrating and would rather not move to another mftr if I don't have to.
My question:
>>> Has anyone successfully installed and run Windows 8 Pro without issue?
>>> If so, can you please provide me with what releases/versions of the drivers you are running and what BIOS version you are running.
Any suggestions or sources would be immensely helpful in my quest to get W8 somewhat usable on this beast.
Thanks in advance!

BSOD on resume:
Happened to a W530 with Crucial m4 mSATA SSD. It turned out that it would happen if the drive is password-protected. After removing the password in BIOS Setup, there's no more BSOD on resume.
So, thusfar, no BSODs on resume. I still have to install the rest of the drivers but at this point, no BSOD since fresh install early this morning. I only have the single Intel 320 SSD in my SATA bay, no mSata drive as of yet. Additionally, I do not have a HDD password. I use the BIOS password w/ fingerprint authentication though.
Post-install, Windows had installed whatever drivers it felt were necessary. After that finished, I had installed Lenovo System Update and went through its update procedure. I elected to install all but:
- ThinkVantage Active Protection (I have SSD, not necessary)
- Audio Driver for Windows 832/864 (Sound works, reports as High Definition Audio Device - I am investigating option for Dolby driver as I had setup in Windows 7 as per W520 Sound Enhancement thread)
- Ricoh Media Card Reader Device (only used a handful of times in the past, will find some cards to test)
Outstanding issues:
- Device Manager reports two non-install devices (Base System Device and Unknown Device).
- Base System Device hardware ID is: NTPNP_PC <-- I don't know what this is, any ideas?
- Unknown Device hardware ID is: ACPI/LEN <-- I assume intel chipset since I had already installed Power Management driver via System Update?
- Update other Windows standard drivers to Lenovo Windows 8 releases
- Update NVidia Drivers to latest release/verde (maybe depending on video performance)
- Setup Fingerprint software in Windows 8 to match that of the BIOS as right now, no fingerprint auth in Win8
- Install Development software, Hyper-v once I have everything else settled
- Anything else I'm forgetting?
Without jumping the gun, it seems as installing using UEFI fixed a few critical reliability problems (VT-d, boot, etc.). Try that if you're having severe stability issues.

Unable to Resolve Windows Update Issue in Windows 8.1

Hello,
I recently, as far back as 1 month ago, began experiencing issues with the update service under the Windows 8.1 OS platform.
I found that I was having to repeatedly run the Windows Update Troubleshooting Tool. This appeared to fix the issue with each run of the tool, but eventually I'd have the same problem receiving updates again. My problem is as follows:
1. Windows Update service hangs during register analysis.
2. Unable to reset (stop or restart) wuauserv.
3. Unable to reset (stop or restart) Cryptserv.
4. Unable to reset (stop or restart) BITS.
5. Unit recently, was unable to connect to internet from Desktop GUI, but was able to connect using Metro GUI.
I'm not sure is there was a recent update that caused this issue, but I can no longer download updates for my system, nor can I successfully run the Windows Update Fixit tool.

Hi,
Let's confirm these situations:
Now your desktop Internet Explorer can't connect Internet.
You receiving the same updates again and again.
If I am right, please check that update's installation status from update history.
Then refer to this article to troubleshoot:

Assamese language India in Adobe PageMaker 7 in Windows 8.1 Pro x64 environment

How can I type 'Assamese language, India' in Adobe PageMaker 7 in Windows 8.1 Pro x64 environment ?
http://answers.microsoft.com/en-us/windows/forum/windows8_1-performance/assamese-language- india-in-adobe-pagemaker-7-in/3f97fbde-332c-48f1-a7f0-62f617af8fde

You will run into many problems as pagemaker is obsolete. It really only runs under win xp. Some people claim they can get it to run on windows 7, 8 but often run into problems when it comes to printing/pdf creation.
The other problem is that pagemaker will only support the first 255 characters in a font, which severely limits it's usefulness. There was a middle eastern version of pagemaker with special fonts, but I don't think it's still available.
I would look into Indesign, but research the language support before commiting to Indesign, as it may require some additional software, and or workarounds. Post your question in the Indesign forums.

On windows 8 and itunes I have importing problems the DVD is only reading the music cd from 1.5x to 4.0x for 95% of the time, it does hit speeds of 30x for the other 5% of the time. Is it a driver issue with the DVD or is it a windows 8 issue?

No. You have no alternative but to plug it into a computer running iTunes and restore it.

Windows Firewall issue, Inbound rule opend all, still not the same as turning off

This is Windows Firewall issue on Windows 8.1 Pro.
Backup Exec server cannot expand a computer node in selection list. I drill down to Microsoft Windows Network/Domain/Computers, then when I tried to expand a Windows 8.1 Pro computer node, it hangs out.
I narrowed this problem to Windows firewall related issue on Windows 8.1 Pro computer.
When I turn off Windows Firewall on Domain profile, Backup Exec Selection expands the computer node of the Windows 8.1 Pro computer. So, I created an inbound rule opening all to BAckup Exec server as following, but it's still not the same as turning off
Windows firewall specifically on Windows 8.1 Pro computer;
Any Local IP address, Any Remote IP address, Any port, Any protocol, All Interface, All Programs and Services, All profiles(Domain, Private, Public)
And there are no rules blocking any which may override the above rule.
Ethernet on Windows 8.1 Pro computer shows profile is linked with Domain, but just to make it work, I selected all profiles.
Even though I opened all available in inbound rule, it's still not the same as turning off windows firewall. Why am I missing?

It looks as something related to RPC(UDP 135), but even when inbound rule is all open, why it matters? RPC seems working fine only when firewall is turned off on domain profile.

Windows vista - issues w/ linksys WRT54GC?

i have a new laptop running windows vista basic and i've tried two wireless routers so far - dlink DI-524 and now the Linksys WRT54GC.
With the dlink, I was able to connect, but unable to create a WEP password. Also, I named the network Home123, but it kept showing up as 'default' in My Networks. my wife was using her MacBook and it kept showing up as 'default' also.
So I purchased the new Linksys WRT54GC because the Dlink was over 2 years old and thought that may have been an issue. Well, tonight, I was able to connect to the Internet again, but the cdrom setup never recognized my router and it never asked me for creating a password.
Does anyone know is Vista has issues with wireless routers? Am I doing something wrong??
thanks!

corleone, thanks, tried this.
but still no dice. on my vista network manager, my pc is connected to the router correctly, but the router is not connected to the internet at all. there is a red X. i asked vista to diagnose it and it said there may be a DNS issue...
can anyone help?
last resort is to get an airport exreme from apple for my wife's mac. but i heard windows have issues with airports..
thanks.

How to Expand the Screen of Windows Server 2003 on VMware Server 2 ?

Folks,
Hello. Because Windows 7 is not compatible to be installed PeopleSoft PIA, I have to install VMware Server 2 and then install Windows Server 2003, that is compatible with PIA, on the virtual machine.
But when I open Windows Server 2003 on the virtual machine, the screen of Win2K3 is very small, and its size is about 1/4 of the screen of my computer screen. This is not comfortable to work for a long time.
Does any folks know how to expand the screen of Windows Server 2003 on VMware Server 2 virtual machine so that its size covers the entire screen of my computer ?
Thanks in advance !
Lucy

Did you already installed the VMWare tools onto your VMWare guest OS ? Generally, it helps a lot to be able to redefine a larger screen definition.
