Windows 10: Network instability issues when serving a website from localhost

Hi guys,

First time poster here.

I have an issue with my Windows 10 Pro installation. Whenever I try to serve a local website from localhost (either using the nodejs http-server, browser-sync etc. or IIS) the request takes ages to process and the assets do not load completely or correctly. This also happens when browsing websites but a lot less frequent.

For example, if images eventually do load, they load only partially or badly decoded - like a messed up jigsaw puzzle.
Even the default IIS website which only contains one .png image out of 3 requests, once it fails to load the image.

Curiously however, today I was doing some debugging from visual studio with IIS Express and the website I was debugging worked perfectly.

If I am to load a static html website using either IIS or a nodejs web-server and navigate to it via localhost or 127.0.0.1 the issue above occurs.
If I open an webpage with File > Open from the browser it works perfectly though - so the issue must be web-server / localhost related.

Additionally, it seems the network is not stable enough to allow file downloads.
Each time I try and download a file from the internet it fails. Chrome says Failed - Network Error while Edge just says it cannot download the file. I have to hit resume several times just to get a few Kb of data.The issue occurred some time after I've reinstalled windows - this weekend.

I'm running windows 10 Pro Insider's build 14965 on a Dell XPS 15 9550. This is the same build I was running before I did a windows 10 reinstall and I did not have this issue.

Things I've tried:
Boot up an Ubuntu live cd - it serves files from localhost perfectly so I don't think it's a hardware issue. Also downloads work
Disable antivirus software - issue still there
Disable windows firewall - no change
Disable IPv6 - nothing changed
Disable any power saving and WMM features from the wireless adapter
Cleared all cache and cookies from the browsers - still no luck
Manually set DNS server
Cleared DNS and WinSock cache/catalog
Reinstalled all network drivers and then some older versions - no change
Did a full network reset - no change

Things that are working:
- Doing a network speed test yields expected results with a decent ping ms time
- Downloading from torrents, doing a npm install or wget works
- General browsing most of the time works though sometime some assets from third party websites fail to load. ie: the wysiwyg editor from this forum did not load from the first try, I had to reload a couple of times.

The only option I can think of now is to do a windows reinstall, but I simply cannot afford doing it during this week *Sad

Has anyone else encountered this issue or anything similar?
Thanks a lot for your help!

IIS not serving local pages on localhost

IIS is serving up my localhost index page but won't serve anything further - click on links on that page and it won't serve them.

The links in question are not links on the web.

They are links to files right there on the local machine.

If I write their URLs into my browser - i.e. localhost/brassrazoo it will happily serve up that page.

But if I write localhost I will get the index page from wwwroot and if I click on a link on that page to 'brassrazoo' it will not serve it up nor does it offer any explanation, any error messages.

I found this in the event log but if this is the problem I'm not sure how to fix it. I looked for the component services admin tool and didn't find it.

The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID

{8D8F4F83-3594-4F07-8369-FC3C3CAE4919}

and APPID

{F72671A9-012C-4725-9D2F-2A4D32D65169}

to the user NT AUTHORITY\SYSTEM SID (S-1-5-18) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.
