Call of Duty: Modern Warfare 2

Hello

This is not the first topic on the problems with Call of Duty MW2 NAT

I bought the WRT120N has a few months ago because I got faster internet (20 Mbps).

I checked CoD MW2 If NAT was open, it was not. I did some research on the internet and after a few attempts the NAT was finally open.

The computer is connected via a cable.

About 2 weeks ago, it was closed again. I don't know why, I changed nothing on the configuration of the router.

Sometimes I save my options again without changing anything and it will open. But now it does not even help

I made some screenshots and maybe someone can see the mistake I made or something.

Le.100 and the end of the ports are correct, as you can see here.

I hope someone can tell me what to do with the NAT will remain open all the time

Kind regards

    I now have windows 7. It was the same thing with Vista! Help, please

    Hi pavz,.

    Some practical information would be useful...

    Your laptop is overheating? You should try to clean using compressed air stream. This could blow out the dust from the cooling fans. You can get the jet of compressed air from each computer dealer.

    The more you use a non-Toshiba display driver? If Yes, you must remove it and install the latest driver for Toshiba page.

  • Call of duty Modern Warfare 2 error: the system administrator has set policies to prevent this installation.

    I have Windows Vista.

    When you try to install COD MW2 disc, I get the following message is displayed:

    The system administrator has set policies to prevent this installation.

    Then it continues with the installation of the first disc perfectly, but the problem occurs with the second disc. When you are prompted to enter the second drive I do and he doesn't recognize. The drive doesn't look like it runs as if it is scanned intermittently. STEAM will freeze and (no response) as well as menu my computer and the DVD disk drive. So far, I can't find any solution to my problem.

    I had the game earlier on the same pc but had to uninstall STEAM temporarily.

    Any help would be appreciated! Thank you.

    Thank you for your response. However I can't find the "local security policy" in administrative tools. Not sure if it's because of Vista.

    However I managed to the second drive yesterday after many many attempts. It seemed to work when I changed the AutoPlay settings to open the folder and view the files. I have no idea why, but he was able to read the disc in this way, after a few attempts.

    Thanks anyway. :)

    Hello

    It seems that the issue could be with the file to install the game. I suggest you to uninstall the game and then get the new installation disc. Reinstall the game using the new drive and see if that fixes the problem.

    I suggest you to check with the game support Men of War for more information.

    • What you have already tried to solve the problem I have updated my graphics records a few days ago from nvidia.com

    The minidump files showed various stop without named third-party driver error as causing the crash.

    One of the errors was an error VIDEO_SCHEDULER_INTERNAL_ERROR (119) which can be hardware related, but could be driver connected.

    One thing c:\windows\system32\drivers\sptd.sys driver has been known to cause various errors blue screen in some configurations, so I recommend you to uninstall the application that has installed this driver, possibly it is Daemon Tools.

    Then, uninstall the c:\windows\system32\drivers\sptd.sys - see "How can I remove driver SPTD on 32-bit operating system?" in the following link:

    "www.duplexsecure.com/en/faq

    Also, remember to update ATK0110 driver for the motherboard, you may need to find the latest driver for Windows 7 under Windows Vista.

    Also, consider updating the BIOS version 1401.

    Hello

    You may notice this problem only with Call of Duty or in other games too?

    It's not easy to say why this is happening but maybe your laptop is overheating and so he died while playing a game. You can try to clean your laptop using a jet of compressed air. This could blow out the dust from the cooling fans. I clean my cell phone every 3-4 months and I m always asked how much dust out. You can get the jet of compressed air from each computer store.

    In addition, you should only use directly display Toshiba drivers because they have protection against overheating. Other drivers could damage your graphics card.

    You have disk problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD burning and)
    Playback of CD and DVD). So it is not unusual for parts from 1 or 2 to not work so that others do
    correctly.

    Step 1: Please do all the same underneath if you did some before as is often total
    a process that solves the problem.

    Try this - Panel - Device Manager - CD/DVD - double click on the device - driver tab.
    Click on update drivers (this will probably do nothing) - RIGHT click ON the drive - uninstall.
    RESTART this will refresh the default driver stack. Even if the reader does not appear to continue
    below.

    Then, work your way through these - don't forget the drive might be bad, could be a coward

    Another possibility is that the cables are loose. Remove ALL power, then make sure that the cables in both
    ends. Remove and replace, do not just tight. For laptops, you can often clean power and
    contacts data with a pencil eraser.

    Some DVD players do not use the Windows default drivers so check with the manufacturer of system and
    manufacturer of device to see if there is a firmware or drivers for your drive if necessary.

    ===============================

    Step 2: You have disc problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD
    Burn and CD and DVD read). So it is not unusual for 1 or 2 operational so that other parts

    Did you follow the Troubleshooting Guide for the reader who still does not work? There are
    the entries in registry that the troubleshooter does not solve and those who "might" be the cause.

    Check with your Maker system and a device for the two possible firmware updates and the
    correct registry entries for your car.

    Here are the keys that I of course are those in question - for the subkeys of the CD/DVD drive
