I have an IIS site, and one of the virtual directories is actually on a separate server, accessed via a UNC path.
Every now and then (several times a day) the ASP.Net application restarts, and in the event log I get :
Event message: Application is shutting down. Reason: Configuration changed.
Now, I know that the configuration has not changed, however I am able to recreate the problem in a test environment by temporarily making the UNC path unavailable, and then requesting a file from it.
I happened to stumble over the following gem on an unrelated KB article (269009):
Microsoft does not recommended using UNC-mapped content on high-capacity Web sites
Now, my question is: Why don't MS recommend using UNC Paths, and what alternatives should I be using instead?
