I have a Windows 10 Pro Insider (v.14936) and since the last update (the 14936), I do not anymore have access to my network hard drives (NAS Synology DS210j and another Thecus N2800 NAS).

Previously I had no problem accessing the NAS, I've also another computer under 10 on my network and this one i've no problems for access it. They both have the same antivirus and the same firewall settings (ESET Smart Security).

Here is the error message I get when I try to open my network drives :

I deleted the credentials stored in Windows.

In addition, following the recommendation of Microsoft support (KB912998) I checked the next local strategy was well off: "Network access: Do not allow storage of credentials or .NET Passports for network authentication"

I tried a system repair using the command "sfc / scannow" and "chkdsk / r" without any changes.

Do you have an idea to solve this problem? Is this a bug referenced in this release?

Thank you in advance for your assistance,
