It appears that Microsoft Word (WinWord.exe) could crash simply because your Windows system is unable to resolve the DNS. If you notice when you launch
Microsoft Word There are certain Word Document Templates to pick from. It seems like Word accesses the following DNS “officecdn.microsoft.com” address to
access its templates. In my particular geo “officecdn.microsoft.com” resolves to the canonical name
It is very likely that Word reaches out to officecdn.microsoft.com download thumbnail images that it presents as document templates to choose from. I think Microsoft needs to
make sure that failure to resolve a DNS record that does result in a crash. It is not
really acceptable for me to be able to at least access local documents even if my office CDN is down.
