EqualLogic Auto-Snapshot Manager Agent fails to start on Windows hosts that are not connected to the internet. This happens because the Host Intergration Toolkit 4.0 uses .NET 2.0.
Each time a .NET application starts, it tries to check revoked certificates at crl.microsoft.com because the server has no internet access the service times out while waiting.
The solution is to increase the ServicePipesTimeout value in the registry.
This can also be caused if the installation of the HIT 4.0 fails to install the Microsoft MPIO feature. The solution is to uninstall the HIT, reboot, manually install the MPIO feature and then install the HIT again.
