Having experienced IIS for many years I've hit this error various times in the past, and understand it, the gist being IIS is attempting to setup so many file change notifications over a UNC share that it is hitting a specified limit of active commands.

However, whilst I understand this is a registry change on the endpoints, in our internal network we're starting to hit this when running certain domains that have large content (and the content is then stored out of source control and instead on a dumb network store).

Given this is a testing environment and rather than changing registry settings (which may not even work for client (dev) machines that run Vista IIS), I'd like to stop IIS setting up all these file change notifications.

Is this possible to do on a per site basis? additionally the configuration can't be in the web.config, if this means having to disable FCN's for the entire IIS server this would be preferred.

Thanks in advance.
