Hi Mike,
If I don't misunderstand, you noticed the following event Log on the problematic Windows Server 2008 operation system.
Log Name: System
Source: VDS Dynamic Provider
Date: Date
Time: Time
Event ID: 10
Description: The provider failed while storing notifications from the driver. The Virtual Disk Service should be restarted. hr=80042505
Please note: This event is logged every time that we shut down and then restart the operating system.
Cause:
This problem occurs if the Virtual Disk service is started. The Virtual Disk service is a "demand start" service that runs only if something has called it to be run. Therefore, the start type of the Virtual Disk service in Services.msc is "MANUAL."
This issue occurs because the Virtual Disk service stops the Virtual Disk providers when it shuts down. When this occurs, the Virtual Disk service unregisters for driver notifications. Then, the service stops the notification processing thread. Because the process occurs in this order, the notification processing thread may call back in to the driver after the provider has unregistered for notifications with the driver. In this case, an event is logged.
Resolution:
To resolve this issue if you have an application, an accessory, or a service that experiences a failed Virtual Disk start, restart the Virtual Disk service.
Please follow the steps:
1. Click Start, type cmd in the Start Search box, right-click Cmd.exe, click Run as administrator , and then click Continue.
2. Type the following command, and then press ENTER:
Net Stop "Virtual Disk"
3. Type the following command, and then press ENTER:
Net Start "Virtual Disk"
Please note: Even if the Virtual Disk service has been restarted once, the issue may still occur after you restart the operating system.
Event ID 10 may be logged on a computer that is running a clean installation of Windows Vista SP1 or Windows Server 2008
