2. Try downloading a copy of the DLL from the Internet to fix DNS error. Most of the dll files are available downloading on the Internet. The new dll files can replace the missing or corrupted one so that you will remove DNS error after restart your computer.
3. Copy the same dll file from a networked computer.If you have a computer running on the same OS or having a similar set of programs installed, do a search in that computer and see if the error can be fixed by that.
