Windows 10: Windows 10 Pro v 1909 and Synology Directory Server

I just bought a new Windows 10 Pro PC and did all of the updates to version 1909. I have an existing network with 3 PC's connected all Windows 10 Pro and all were upgraded from previous versions to version 1909. I am attempting to connect the new PC I bought to the Domain which is a Synology AD environment. I have set the adapter to the DNS server which is on the same server as Synology Directory Server 192.168.1.5. The forwarders on the DNS server point to Open DNS and Google respectively.


When I input the domain name to join the domain, I get:




When I open a command prompt and ping the domain name, I get:





I am unsure of what to try at this point. I know the Domain is active and working as I have joined 3 other PC's at an earlier time. It seems just this new PC won't connect.

Windows 10, Synology samba server - random disconnecting

Hello,

Since update to Windows 10 my users have a lot of problems to work normally.

We have such topology:

• DFS namespace
  • link1 to synology share
    • shared dir 1
      • shared file 1.1.pdf
    • shared dir 2
      • shared dir2.1
        • shared file2.1.1
  • link2 to synology share
  • etc

And since update to Windows 10, everyday after some time of work user (random time) has problem that file explorer 'taking' him up in folder view, for example user is in 'link1' -> go is trying to go to ' shared dir 2'. This is steps he follows:

• Going to 'My computer' -> everything ok
• going to mapped drive with dfs namespace -> everything ok,
• going to link1 -> everything is ok
• going to shared dir 2 -> everything is ok
• going to shared dir 2.1 -> for 2 seconds explorer is showing list of files and going again to 'shared dir 2',
• users is trying again to go inside 'shared dir 2.1', now file list is present for 1 second and file explorer go up, 2 directories above!
• next time user is trying to go inside he will be in DFS namespace.

Other links to synology shares during this time is working normally.

User has to wait for about 10 minutes (maybe oplocks?) to get into folder.

Other directories in 'link1' during this 10 minutes are problematic too.

Let's say we have pdf file shared file1.1.pdf, we are going into folder and trying to open file, we have such statements:

• in Acrobat reader - file doesn't exist
• in Windows 10 pdf browser - white page,
• in foxit reader - Unknown error,
• in Google Chrome - file opens normally!

Do you have any idea what's going on and/or where to look for some answers?

• I cannot find any logs saying about lost connection or permission denied.
• I've created Windows Firewall rules to disable firewall for domain
• we have Eset firewall installed, but our LAN is in trusted zone and teoretically it is set to allow everything from that zone

 

How To Map Synology DS918+ w/ 32TB

Check-out my Synology Community post I did some days back on this lousy issue together w/ a video I've done about mapping Synology NAS Shares on either Windows 10 20H1 / windows Server 2019 version 1809!
How To Map Synology DS918+ w/ 32TB

General details of the issue are pasted below!

Mapping a DS918+ NAS to either Windows 10 20H1 / Windows Server 2019 1809.



Please note that the Synology DS918+ NAS does map to the following editions of Windows 10.

Windows 10 Pro/Enterprise version 20H1 & above

Outlook Personal Account Required-

Full & clean installation of Windows 10 20H1 (Build 19041.84) done on March 4th, 2020 using only an Outllok personal account & the Synology DS918+ NAS works fine w/ it! - Also on February 29th, 2020 - I succeeded w/ an upgrade from Windows 1909 to Windows version
2004 (20H1) using a personal Outlook account & mapping does work as you can see w/ Windows 10 Insider Preview 19569.1000 (rs_prerelease) 20H1 w/ all fast updates applied, together w/ all my regular software!

Use the NAS login Device + Share & password!

NAS connected to network via a switch requires User + Password

Avoid any Microsoft Azure / Onmicrosoft & Contoso Accounts - until either you've or an IT professional has correctly configured the Synology DS918+ NAS for Microsoft Azure usage!

Avoid any any full & clean Windows 10 Pro/Enterprise/Enterprise LTSC 2019 installations w/ any Microsoft Azure logins - due to NAS volume share mapping failures w/ Windows 10 w/ the Synology DS918+ NAS until the NAS has been configured for MS Azure! - In other
words if you sign in to Windows 10 either w/ an *.onmicrosoft / *.contoso account(s), even if an Azure account login is created afterwards - (I just tried this yesterday on March 4th, 2020) - as an add-on to a personal Windows 10 Outlook login account & the
Synology DS918+ NAS volume share mapping fails!

Windows Server 2019.

If you need to sign in as a business account rather deploy Windows Server 2019 & above, or you could possibly use a domain account w/it too - as windows Server 2019 Standard/datacenter works well w/ the DS918+ NAS!

Synology Assistant

Anothder thing to avoid is not to install the "Synology Assistant" on "Windows 10 20H1" as it fails to discover the DS918+ NAS device! - You don't require the "Synology Assistant" for mapping any Synology NAS Shares on either "Windows 10 20H1" / "Windows Server
2019"!

For mapping all Share volumes - use the NAS login Device + Share & password - w/

If upgrading from Windows 1909 to Windows version 2004 the Synology DS918+ NAS shares mapping will work as a result of completing the Windows 10 upgrade w/ all updates applied!

For best business results rather deploy Windows Server 2019 Essentials/Standard/Datacenter

⦁ Windows Server 2019 Essentials/Standard/Datacenter Version 1809 / Build 17763.1039 & above

For Synology DS918+ / as well as other Synology NAS devices-

Do use the "Synology Web Assistant" w/in either Windows 10 20H1 / Windows Server 2019 w/ either "Google Chrome / Mozilla
Firefox" as these will discover your Synology NAS in around 15 seconds (w/in less than a minute)! - Avoid using either "Microsoft Edge / Internet Explorer 11" as both these fail to discover your Synology NAS!

NAS / System Image Backups & Restores

wbAdmin start backup -backupTarget:\\DS918\Images -include:C: -allCritical -quiet

Windows creates system images snapshot backups in different folders on non-system hard disks!

Example Share-

"\\DS918\Images\WindowsImageBackup\DESKTOP-XXXXXXXXXXX" where the 11 X's are last part of
the name of your desktop machine!

Or use either an internal/external HDD option-

w/ any "D" through "G" hard disk options to use!

wbAdmin start backup -backupTarget:d: -include:c: -allCritical -quiet

Windows creates system images snapshot backups in different folders on non-system hard disks!

Example-

"D:\WindowsImageBackup\DESKTOP-XXXXXXXXXXX" where the 11 X's are last part of the name of your desktop machine!

Use an appropriate internal/external non "C" Drive -backupTarget drive option for system images!

Synology sign in

I have a new windows 10 HP laptop v1903. Clicking on this PC shows connected devices. My problem is that clicking on DS.213j opens the Synology hard drive without a password being needed. I usually open the Synology in my main PC by searching under
"Internet" where it can be opened but requires a password. On my laptop the Synology is not listed under "Internet" only HP Laptop is listed.
