Could not load file or assembly 'SSPI.dll'

Symptoms

When scanning a VMware vCenter server with XIA Configuration Server v9.1, you may see the following error:

Could not load file or assembly 'SSPI.dll' or one of its dependencies

- or -

Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime

Cause

This is due to a bug in the SSPI.dll used to provide SSPI support for the VMware system agent. This allows the system to scan a vCenter server running on Windows using the service account credentials.

Resolution

To resolve this issue, please upgrade to the latest version of XIA Configuration Server.
