I just configure IIS 7.5 and was installed my we site. All working good with files less than 30mb. But if i uploading files bigger 30mb progressbar doesn't filled and after 1.5 minnutes i'll reciving error -
404 - File or directory not found.The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.
After pushed the upload button i saw incomming traffick on server, this is mean the file i selected is uploading. But after 1.5 minnutes connection is refused and files not copied.
