I have a windows 2008R2 server with IIS 7.5, and I have repeatedly had an issue with it deleting my custom MIME types. I'll add one, and anywhere from a few days, to a few weeks or months, it will just disappear. has anyone else here experienced this? I have had absolutely zero success in finding a solution on google, when searching for "IIS 7.5 custom mime types lost" and I've tried replacing the last word of the search with "missing", "disappear", and "deleted" with no useful results. all of the results returned tell me how to add a custom MIME type, but I already know how to do that :-\
