    Hi,

    Looks that I hit the bug in the Ethernet driver of the Parallels - in some situations it's crashing the guest Windows (XP) OS - BSOD (Blue Screen of Death).

    After installing the Cisco VT Advantage (video conferencing support for Cisco Call Manager) as soon VT Advantage starts - it's crashing the Windows Guest OS to blue screen of death.

    After investigation I see that the crash occurs as soon as VT Advantage calls it's CDP driver (to handle Cisco-proprietary L2 Cisco Discovery Protocol) which tries to communicate with the Parallels Ethernet driver.

    Looks that this problem is specific to Parallels - VT advantage works just fine under Fusion.

    Anyone seen something like this?

    Here are details about the drivers:

    Cisco VT Advantage + iSight + Macbook pro = Blue-Screen-Of-The-Death

    Hi

    Same issue down there!

    Setup:
    Model Name: MacBook Pro 15"
    Model Identifier: MacBookPro2,2
    Processor Name: Intel Core 2 Duo
    Processor Speed: 2.33 GHz
    Number Of Processors: 1
    Total Number Of Cores: 2
    L2 Cache (per processor): 4 MB
    Memory: 2 GB
    OS: Mac OS 10.4.10 (Tiger)
    Parallels Desktop 3.0 Built 5160
    Guest OS - Windows XP PRO SP2

    Isight is working fine with my Win XP PRO.
    Cisco VT Advantage installation is ok.
    But I soon as run it when the laptop is connected to my Cisco IP Phone (7970) via ethernet, it generates the BSOTD - error PRLETH.SYS

    Tried to add more memory RAM + Video but no change.

    Please Advice.
    Thanks

    Since Parallels ethernet driver crashes, I would try replacing it with a Realtek 8029 driver.
    Please try this:
    1) Open the start menu and go to Control Panel.
    2) If you can switch it to classic view, do so.
    3) Double-click "System"
    4) Go to the "Hardware" tab and click "Device manager".
    5) Open the "Network adapters" and double-click Parallels Network adapter.
    6) Go to the "Driver" tab and select "Update driver"
    7) Say "Not this time" to a windows update prompt, choose to install a driver from a specific location. Click on "Don't search, I will choose the driver to install"
    8) Select a Realtek RTL8029(AS) ethernet adapter (universal). Or you can try any other Realtek 8029 adapter.
    9) Install this driver, restart the virtual machine and see if the crash persists.
