12210 An Internet Server API (ISAPI) filter has finished handling the request

What is going wrong if you see the following logs in ISA server management console and users complain about missing parts in the web page?

12210 An Internet Server API (ISAPI) filter has finished handling the request. Contact your system administrator.

Don’t worry.  It’s not your fault, it is your web filtering software tells ISA that something has been blocked so don’t try to fetch anything more from there.

In my case, it is gravatar.com.  This website provides some components in WordPress.com, but it is also listed as a malware site and is blocked by the web filter plug-in in ISA server.  That also explained why I could never edit WordPress Widgets in office but everything is fine at home.

It’s not a good news for Gravatar for years; but seems the owner Automattic has never put any effort to clean up the reputation of their domains.  The open source world is too liberal to get controlled.

ISA, TMG. No more.

Heard this news after vendor visited us yesterday.  This vendor has been developing proxy-kind products instead of just Microsft plug-in for several years and they keep promoting their software and appliance to us, also another vendor has been on the same track for a while although they are not so much actively selling.  But Microsoft’s roadmap for Forefront or TMG proxy product was not very clear in the past few years, TMG, UAG and codename ‘Stirling’ are always confusing, even to a technical guy like me; and there’s no exposure in any recent Microsoft events.  Also I heard Microsoft didn’t really make money from ISA/TMG, maybe that is one of the main reason behind the whole story.

Still trying to swallow this news as Mrs. Shinder did, although this may not be a news anymore after two months since it’s revealed by Gartner (not Microsoft!).

Here are some links I found informative and helpful:

A summary of Gartner’s report can be downloaded from McAfee site, link in this blog, I am not sure if that is the $1995 one.
