[Samba] Non Samba question

Hai Bob,

> I have a almost non-Samba question, I think. So, I do not want to post it to the forum, yet. 
Yes yes, i remember you :-) , and i have no problem with direct messages. 
How are you doing? 

I'll reply to the list with a CC for you. Because this involves samba also. 
And this might help others also. 

Slugghish windows 10? There are may ways to fix a "sluggish" windows. 
One example: 
- With (almost) every click you do in windows a dns request is involved and internet is accessed. 

This is also why i hammer on a correct resolving setup, this helps in speeding up you windows.

So here it starts DNS/Resolving. 

Example : Windows cannot access \\server check the spelling of the name 0x800704cf 
That involves all links below. 

Read:
https://tools.ietf.org/html/rfc2606 
https://tools.ietf.org/html/rfc6761
https://en.wikipedia.org/wiki/.local 
https://tools.ietf.org/html/rfc6762

Other good articals with examples, ( must read )
https://social.technet.microsoft.com/wiki/contents/articles/34981.active-directory-best-practices-for-internal-domain-and-network-names.aspx

And a security consideration:  https://www.us-cert.gov/ncas/alerts/TA16-144A  (Leaking DNS info)

This is a must read :
https://support.microsoft.com/en-us/help/909264/naming-conventions-in-active-directory-for-computers-domains-sites-and  

And looking at table 6.2 here: 
https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-2000-server/cc959336(v=technet.10) 

Your resolving should match this : ( at least for an AD-DC/LAN network )
- hostname , min 1, max 15 characters, a-Z,0-9, -
- DNS domain name, max total FQDN 254 characters, include the dot's. 
    And 254-15, results in 239 characters left for the domain.tld part.  
    The FQDN for an Active Directory domain name is limited to 64 bytes.

When this is perfect, you will notice and increase of speed in you windows 10. 

(BOB)>  I always felt like, but could be wrong, that with one of the previous W10 upgrades, windows changed something and my file explorer was suddenly slower.  
Yes, you are correct, more and more is going to internet, unless you disable/block it. 

Themes, set the most simple, plain themes, what you set at home is up2you, 
	but for businesses, keep is as simple as it is possible. 
In GPO : 'User Configuration > Administrative Templates > Start Menu and Taskbar > Notification', Turn off tile notifications

Make you windows less fancy but much faster. 
- Disable Effects & Animations 
- Set visual effect to Best performance. 
- Disable Transparency Effects
- remove/disable Cloud Sync.
- Disable "Fast startup", yes, you pc might start a bit faster,
 but it will give you some nice problems back in the end, due to power saving/hibernation/Sleep states. 
 A reboot is not reboot anymore, it unloading/loading windows ( not powercycle) ! 
 Disable it to be able to reboot your pc normaly. 
 Laptop/notebook might suffer from these problems and even worse, some have these settings enable in the bios 
 And windows will pick up these settings. 
- Computer Configuration > Administrative Templates > Windows Components > Search. Disable Cortana
- Unpin Quick-Access, just disable it or remove the "Work ...." parts. 
  Or set the Quick-access to "Open File explorer to "this PC" 

- Windows 10 frequently performs optimization in the background and that can cause File Explorer to be slow.
  Fix it with : 
Right-click the folder that’s slowing down File Explorer. Choose Properties from the menu.
Go to the Customize tab.
Set Optimize this folder for to General items. If this value is already set, select any other value from the list. After that, switch it back to General items.
Check Also apply this template to all subfolders.
Click Apply and OK to save changes

- the index might be corrupt, fix it by rebuidling the index. 
Press Windows Key + S and enter indexing options. Choose Indexing Options from the menu.
Advanced : Now click on Rebuild button.  ( optional change index locations. ) 

- Clean up windows and check up windows. CMD with Adminitrator rights. 
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth

- Clean up your windows with "Disk cleanup" first as user, then as Administrator, then select all you can. 
Tip, do this before all major updates of window 10, this helps preventing windows 10 upgrade. (like 1803 to 1903 upgrades)
It will easily save you 10-20GB on your pc.

In a LAN, enable, Wait for Network in the GPO. 

https://www.spinics.net/lists/samba/msg159233.html 
Shows the suggested services to enable (slowed down at start up)
! NOTE, I personaly, have not changed these settings, because its not needed here. 
GPO and correct DNS does it all for me.

-  Use netsh winsock reset command

-  Disable the TDM service if you dont use it. 

A "small" part of my arsenal in batteling windows. 
Yes, i have more, but above helps in 99% of the cases. 

Greetz, 

Louis

I hope you remember me from a few years ago. And I apologize for the direct message.
I have a almost non-Samba question, I think. So, I do not want to post it to the forum, yet.

	In this post on the Samba forum,"[Samba] Windows cannot access \\server check the spelling of the name 0x800704cf" you mention checking some Windows settings and creating a GPO for them. 
I just had a quick look at the thread. A long threath... 

	I first checked your suggested settings on one workstation and these services were not enabled. Then I created a GPO to push these settings to all workstations. Forced the GP update and check services again and all were enabled.

	Prior to changing the settings (you suggested), for the longest time I had "sluggish" file explorer issues and changing these settings greatly improved the sluggishness.
 I always felt like, but could be wrong, that with one of the previous W10 upgrades, windows changed something and my file explorer was suddenly slower. 
Yes, correct, with so many things in windows getting things from the internet/ms servers, its making you pc slow. 

	When these changes were made other domain services improved. Occasionally my 'profiles" would not load at workstation start up. Now with improved network setting (you suggested) I have not experienced these failed profiles issues, as yet.

		Have you ever had an experience similar to mine (sluggish file explorer) or a similar complaint from a customer like this? Where there any other GPO you created or know of that might help the connections between W10 and my domain members?

	I attempted a question similar to this on the forum but got one answer which actually was a non-answer from some guy who does not use GPO.
	forum? Samba forum? 

	This turned into a longer email than I expected, sorry.

	-- 

		Thank you.
