Hyper-V-Integration EventID 4096

Sometimes you see warning in the Event Viewer for Hyper-V-Integration.
“EventID 4096 The Data Exchange integration service is either not enabled, not running, or not initialized.”

In previous cause for me it was a HAL problem as sometimes you import a VHD previously created in virtual server or virtual PC to hyper-V.

If the operation system is Vista Remove the ICs and do the following steps

1. Start msconfig
2. Go to the Boot tab
3. Click the Advanced options button.
4. Check the Detect HAL checkbox.
5. Click OK.
6. Click OK.
7. Reboot the VM.
8. Install Integration Services.

To update HAL for XP

 1. Boot off your Windows 2000 or XP CD.

2. When asked if you want to install or repair your current installation, choose Install.

3. Then, follow the steps to upgrade Windows (even though you’re not technically upgrading, you are updating your HAL).


I found another work around for this problem… you can test it.

 First Take a snapshot if it’s not already done because we never know what is going to happen, then simply delete (or rename) two file on the guest machine

C:\WINDOWS\system32\DRIVERS\wdf01000.sys and


After that, you just need to reinstall the integration services.

    The workaround may not work I tried this and when windows VM boots it looks for this file and fails “wdfldr.sys” I luckily did create a snapshot as suggested. I will try just renaming the “wdf01000.sys” and report back the findings.
