Ping can use previously failed cached record,  nslookup doesn’t use the cache, it queries the DNS server directly

Try this:

on the client machine,  run  ipconfig /flushdns

Problem:

After creating share on Windows 2016 server (workgroup enviroment), the users can not access the shares. The permissions are correct.

Option 1  Do it manually. 

Step 1  Disable 4 Windows services as shown in the pictures. (create a fake user account abc, and delete it after.)

• Delivery Optimization
• Background Intelligent Transfer Service
• Windows update
• Update Orchestrator Service

This step is very important, make sure to type in an incorrect password. The idea is that the service can not start if the credential is wrong.

Windows 10 updates will be disabled if those services can not start.

Step 2 Open Task Schedule, and

• delete scheduled Windows update items and Windows update folder.
• delete UpdateOrchestrator items and UpdateOrchestrator folder

Step 3 run cmd as Administrator     sc triggerinfo wuauserv delete

Option 2 Using a software. 

Run the Windows update blocker program Win10UpdateStopper.

Problem:  

One user can not use Start Menu and settings. So I created a test account, the test account has no problem use stat menu and settings

Solutions:

If a new created user account has no problem to use the start menu and settings, that tells me that the Windows system might be  OK. The “bad” user account might have a corrupted profile.

1: Log in as the new created user.

(You need to create a second Admin account to do this.) You need to enable “show hidden files….” and disable “Hide protected operating system files”

2: Go to c:\users\bad-user name\appdata\local\Microsoft\Windows find UsrClass.dat  rename it UsrClass-old.dat

3: Restart the computer

The problem should be resolved.
