Multi Proc Windows 2008
Use us many multi-proc machines so I was curious about the best practices for multi processor Windows 2008 conversion. Is there the same limitations on adding and deleting of the processors were in 2003? From my tests it looks like the PC ACPI x 86 or PC ACPI x 64 is used regardless of the number of processors that you are running. Is this correct? Any help from the community would be greatly appreciated.
Hello.
From my tests it looks like the PC ACPI x 86 or PC ACPI x 64 is used regardless of the number of processors that you are running. Is this correct?
I know that changing of 1 to 2 and then return only Exchange not the layer HAL in 2008. I have not tried with more than 2 CPUs. The limitations and the changes that have been in 2003 are certainly not during the passage of 1-2 or 2-1.
In this TechNet article by Mark Russinovich, he explains the changes in 2008. One of the quotes:
"One of the changes to the low level system is that Windows Server 2008 includes only a version of the kernel designed to run on multiprocessor systems. In the past, Windows used a specific version for single processor on machines with a single processor, because this version could achieve slightly better performance by omitting the necessary synchronization only code in multiprocessor environments. As hardware has become faster, the gain of performance optimizations has become negligible, and most server systems today include more than one processor, making it a useless uniprocessor version. »
Good luck!

VMWorkstation on Windows 2008 server
VMware workstation 7 usable with Windows 2008 64 bit as the HOST operating system?
therefore vm workstation allows me instant unlimmited... well based on available disk space. I have a new server with 16 GB of RAM and need for an operating system that will support that
Workstation, as the name suggests, more for the premises of the virtual computer, saves key strokes, experimenting with libraries and dev tools. If you have a real server, I still say VM Server will do what you want, and it's completely free. If you are just testing, Server (especially on Windows 2008) is what you want. Not my computer. They will do the same thing in the end, but it is designed for a machine environment virtual multi.
Server has unlimited snapshots too. If your server is remote. you have the ability of remote management, which can be a problem with the workstation, because it is not designed for the server in mind.

Installation of Windows 2008 R2 x 64 as virtual machine using workstation7
Hello
I am trying to install Windows 2008 x 64 R2 as virtual machine on VMware on an ASUS Wndows7 teacher a new computer workstation7 laptop with i3 proc. I use an ISO image downloaded from Microsoft downloads.
I get an error as follows:
A required cd/dvd drive device driver is missing. If you have a driver floppy disk, cd, dvd or usb please insert now.
When I try to search for the driver on flopp or cd/dvd, it is unable to find it.
Could you please help me with this one.
Thank you and best regards,

Hello and welcome to the forums.
This error is most likely due to a corrupted ISO download. Try to download it again and see if that corrects the problem.
Good luck!

Re: Toshiba Store Alu 3.5 "1 TB HARD drive works only with Windows 2008 64-bit
Just bought this as a backup device for Small Business Server 2008 running on Windows 2008 64-bit. However it does not? Are there drivers anywhere for this or it is simply not supported and I need to buy an alternative solution?
Plugged into my laptop Windows 7 64 bit and no problems.
Someone else had the same problem?
Hello
Unfortunately, there is no other software by download.
I checked the driver page Toshiba in the Options area but didn't find anythingAFAIK it of a plug & play HARD drive if you n t need any software to recognize the HARD drive
There may be a password.
Try this:
Connect your HARD drive to the computer when the HARD drive is working
Select the CD drive with your browser (password)
Run the ONSPCLCK.exe
Select 'Options '.
Select "Disable security password"
Enter your current password
Unplug the HARD drive
connect the HARD driveNow, it will work, but with no password protection. Perhaps it would work

I hope someone out there can help you, we have recently tried to upgrade an instance of MBAM version 2.0 to version 2.5 and have received the following message is displayed:
"This version of this file is not compatible with the version of Windows you are using. Check your computer's system information to see if you need a x 86 (32 bit) or x 64 (64-bit) version of the program. »
The upgrade was performed on an instance of Windows 2008 R2 64 bit and we are work struggling on why this product could not recognize the operating system? Especially given that all the prerequisites were followed to ensure that we could run the upgrade.

Windows 2008 Server Standard not install KB3099860 with error code 8000FFFF
Hello
I look after 3 x Windows 2008 Standard Edition servers. Two of them to date very well and are up to date with updates. One of them however, which is identical in hardware to either of the other two and even fewer programs (we use it as a simple file server), fails on the last update released December 2015:
KB3099860 a security update for the .NET Framework 3.0 Service Pack 2 in Windows Vista Service Pack 2 and Windows Server 2008 Service Pack 2: 8 December 2015
I tried a variety of things after having studied the problem these past few days, including:
1 Uninstalling some updates before this one and see if they re - install. They are all re - install fine until I get to it where it fails with 8000FFFF error code so this leads me to believe that this is not in itself a problem with updates
2. manually and also linking this Microsoft 'fixit': http://windows.microsoft.com/en-us/windows-vista/windows-update-error-8000ffff
3. how to install the System Update Readiness Tool for Windows Server 2008 that installs but does not report errors
4. manually by downloading the fix and trying to install - does not work.
5. all the details here: https://social.technet.microsoft.com/Forums/windowsserver/en-US/ae6e81e9-5c49-4826-89bc-04a676992706/error-8000ffff-windows-server-2008?forum=winservergen
including rename them the folder C:\Windows\SoftwareDistribution Windows Update and giving of right on drive C for "Network Services" - still does not work.
6. as it is associated .NET I tried to repair .NET facilities that exist on the server (2, 3, 3.5 and and re-apply updates, but even once, fails on it.)
So, what should I do now? The behavior may suggest that it is that only this particular associate .NET that is a failure and that future ones will work, but it's "critical" and which relates to the .NET version which is initrinsic to the Windows 2008 operating system I think I should get it fixed :)
Any thoughts?
Thank you

Search for content in pdf files stopped working after the migration of Windows 2008 Indexing Service
Hello
We have designed a search custom as an aspx page that uses the Indexing Service to search for content in a set a which coexist document types (doc, pdf, xls, etc.)
We moved to a Windows Server 2003 Indexing Service to Windows 2008 and since the Indexing Service has stopped the search pdf files. The search returns only another type of pdf files.
On the new server where the Indexing Service, I installed Adobe PDF iFilter 11 for 64-bit platform, I think it's the plugin the Indexing Service uses to find the content of pdf files.
Does anyone got the Search Indexing Service content in PDFs on Windows 2008 server?
