Blueprint Administrator Error (141254): "The Model Manager is currently unavailable. Please try again shortly."

When I click on the Assets\Devices context of the Blueprint Administrator I receive the following error message:

Blueprint Administrator Error (141254): "The Model Manager is currently unavailable. Please try again shortly."

(see attachment)

Microsoft released a security hot fix to .NET on July 10, 2007.

This stops .NET Remoting from working unless the following Pharos server components also have the hot fix applied:

1. Analyst server

2. Collector server

Clients are advised to download the hot fix and apply it to all Pharos server components.

If clients feel unsure that this is the cause of the problem they should check the Administrator logs for the following error line:

Error: Type missing for member of type Object '_ContextID'
