Reposting this here since I posted in the wrong section here, so mods delete the old one if desired.
I only have this problem with Win10 Pro x64, regardless of the version/build numbers (v1511, build 10586.29 currently). Wired directly to my TrendNet AC1900 (problem has persisted through multiple FW versions).
After making a few connections to my network location that I add, in this case a WebDAV file server for school I use, Windows will eventually decide that the location doesn't exist anymore. If I remove the drive, and add it again via "Add a Network Location", no matter what address I enter, the location "...doesn't exist..." (click for image). The wizard will start, I give it an address, and after a few moments it tells me it cannot find the location, while the Windows Security box's bar is still moving from left to right trying to connect.
If I use a third-party program, it will work at first like above, but after I connect so many times after system shut downs, these programs will eventually stop working too (but they at least retain a cache so I can view my drive offline); this is because Windows Explorer decides again the location doesn't exist. If I decide to boot via my Win8.1 install, it works as I would expect it to. EDIT: A few days later I tried one of the 3rd party ones (MountainDuck/WebDrive for example) and it's working again. I imagine it will eventually quit again though like before.
I've done everything I can think of to rule it out including:
- Disable AV suite & protection/defense components
- Make sure any networking related services are running
- Use DMZ on router briefly to rule it out
- Using Windows Troubleshooter
- Disable firewall
- chkdsk (via my USB copy)
- DISM repairs via my install.wim file
- Run system repair (via my USB copy)
- Contacted the IT individuals running our WebDAV setup, who claim it's a Win10 bug/problem (which I thought it was too)
- Reinstalled board manufacturer network driver, and later a generic Intel based one.
- Disabled unnecessary adapters (IPv6 support, Atheros, TA)
Interesting enough, this is a relatively clean install. My first Win10 install had huge problems with the v1151 update, so I formatted and installed Win10 v1511 right before Thanksgiving. This problem, exactly the same, occurred with my first install too, eventually just ceasing to work like now. Whereas I'd expect the problem to start after I installed some program or service, it always happens a few weeks later out of the blue, when nothing new has been installed that could explain why it stopped working (or at least to me).
At this point, I'm lost and don't know if this can be fixed, or if this is another problem to add to the list of "Windows 10 killed networking in general".
I've attached a CBS log if anyone is curious, and MTB log, but importing my install.wim file doesn't change it, nor does it probably help that I change my login background which I know also makes the system find errors. MTB insists on only pinging via my IPv6 connection, which does work, but times out. Anyhow, pinging anything via IPv4 works fine, and connecting directly with IPv6 works fine, a la ipv6.google.com.
It'd be great if this is something that can be fixed! Sort of desperate at this point since I can't figure it out and it's bothering the heck out of me.
