Situation: The client just configures Local Administrator Password Solution (LAPS) on their domain. It works for a while. Now, most domain computers don’t install LAPS and LAPS doesn’t change the administrator password..

Troubleshooting: 1. gpresult /R shows the LAPS policy has been applied to the computer.

Applied Group Policy Objects
—————————–
LAPS GPO
Default Domain Policy
Local Group Policy

2. The Event Viewer shows this error.

Log Name:      System

Source:        Application Management Group Policy

Event ID:      101

Level:         Warning

Description:

The assignment of application Local Administrator Password Solution from policy LAPS GPO failed.  The error was : %%1274

Resolution 1: Enable the Specify startup policy processing wait time

1. On the Domain Controller, run Group Policy Management

2. Right click on the policy you want to modify, for example LAPS GPO in our example, click on Edit.

3. Navigate to:

Computer Configuration > Policies > Administrative Templates > System > Group Policy.

4. Enable the Specify startup policy processing wait time or Startup policy processing wait time. Set Amount of time to wait (in seconds): = 90 or more for a test.

Resolution 2: Enable Always wait for the network at computer startup and logon

1. Repeat resolution 1 step 1 and 2.
2. In a GPO that applies to that computer, add the following setting:
   • Computer Settings
     • Administrative Templates
       • System
         • Logon
           • Always wait for the network at computer startup and logon – Enabled

3. Check Enabled

Resolution 3: Make sure the computer can access the LAPS software and have permissions. For example, you may assign everyone to access the LAPA shared folder for a test.

Resolution 4: And I just found another different cause of this error. If you have “Spanning Tree” configured on the ethernet switch connected to the problem workstation, it will delay activation of the switch port when the PC boots up. Disabling Spanning Tree for the switch port or enabling “Spanning Tree Portfast” for the switchport solved this problem on a few of my workstations.

Situation: The client just creates a new mailbox for group users. However, none of the users can’t see the emails with this message:

“We didn’t find anything to show here”

Resolution 1: Changing Hidden state to ‘Compact’ or ‘Preview’.

1. Click on the specific folder where you receive error ‘We didn’t find anything to show here.’

2. Select the ‘View’ tab from the Outlook toolbar.

3. Click ‘Change View’ from the ‘Current View’ group.

4. In the resulting drop-down menu, does it say that this folder has been set to a ‘Hidden state’?

5. If so, please change it to ‘Compact’ or ‘Preview’ (depending on your preference).

Resolution 2: “Reset View”

If “Reset View” was grey, click on the “reset View”. that may fix the problem.

Resolution 3:  I just turned off my message preview and all of the mail in my box showed up.

Resolution 4: It could be you reach some of Outlook limitations such as account limitation, session limitation, folder limitation, space limitation and email limitation. Googling for these limitations.

Situation: The client has Synology NAS. After he adds a domain user to the NAS and assign permissions on the user by going to Domain/LDAP.

However, the user can’t see Control Panel and Package Center.

Resolution: You need to create a domain group and join user in the group. Then go Control Panel -> Domain/LDAP -> Edit -> Advanced -> Domain Administrators -> Add the group.

Situation: The client installs some network on their Windows 2019 Server. However, those printers don’t show in Printers & Devices.

Resolution 1: Run Services and restart the print spooler.

Resolution 2: Restart the server.

Resolution 3: Check any Windows updates holding. You may install them and restart.

Situation: The client tries to create backup storage on Veeam backup. They have a problem to access one of shared folders.

Case 1: Make sure you have assigned the permissions.

Situation: You may receive a notification “Storage pool 1 has reached the space alert threshold”, despite having plenty of space available in the volume.

Causes: If the capacity of the created volume is larger than the configured Storage Pool threshold, the error message will appear. In our example,

Volume Alert is setup 80% of 5.28TB

Storage Pool Alert is setup 90% of 5.44TB

5.28/5.44=0.970588, which is over 90% so that you receive the alert.

Resolution 1: Adjust Storage Pool Alert to 98% by going to 1) Storage & Snapshots > Storage > Storage/Snapshots. 2) Select Storage Pool. 3) Click Manage to open Management Window. 4) Click Action. 5) Select Set Threshold.

Resolution 2: Disable the predefined threshold on Storage Pool Alert.

Resolution 3: Shrink the volume size so that the allocated capacity becomes lower than the predefined threshold.

Situation: The company has 3 email addresses, a.com, b.com and c.com. One of users doesn’t receive emails on b.com.

Troubleshooting: From User Properties > Attribute, we can see all 3 email addresses are there.

However, Aliases under Office 365>admin center>Active users shows only two email addresses.

Go back to User Properties > Attribute, we find smtp: and b.com email address has a space on username,  for example smtp: username@b.com. Changing it to smtp:username@b.com and re-syncing  fixes the problem.

Situation: The user reports that her laptop Taskbar s empty after login windows. Another user login the same laptop or using her account on other laptop don’t have this issue. it must be the user profile issue.

Resolution 1: Delete the user profile and re-login to create a new user profile.

Resolution 2: Run System restore. If you have a problem to run system restore using GUI, try rstrui.exe command from Task Manager.

Resolution 3: Uninstall recent updates.

Resolution 4: Reset This PC.

Resolution 5: Delete HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\IrisService from Registry. 

1. Press the Ctrl + Alt + Del keys and select Task Manager.

2. Click on File and then Run new task.

3. Type cmd and click OK.

4. Type this command

reg delete HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\IrisService /f && shutdown -r -t 0

and press Enter key.

5. The PC will restart.

Resolution 6: Update the Display driver from Device Manager manually and check if the issue is resolved.

Step 1: Press Windows key + X and click on Device Manager.

Step 2: Expand Display Adaptor.

Step 3: Right click on the video driver and select Update Driver Software.

Step 4: Restart the computer.

Resolution 7: Right click on Start > Select PowerShell (admin)

Type or copy/paste the following command into the window then press Enter.

Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}

Ignore the errors in red. When the command finishes, reboot the computer and verify everything is working as it should.

Resolution 8: I advise Resetting the pc or if you have the Windows Creator Update roll back to the previous build and wait for updates.

Resolution 9:

I’m on the Insiders Build and this is something that had been giving me some trouble for a while.  First, I had been pointed to the IrisService but that was a dead-end, and then I also been told to restart the WSearch service which may have worked but wasn’t consistent.

Finally, someone mentioned trying to restart explorer, so I decided to give that a try.  You could probably get this accomplished with cmd but I tend to use PowerShell more.

Get-process -Name explorer | Stop-Process

This killed the Explorer process and the Taskbar immediately came back and is working fine now.  I’ll see if I can try to reproduce again to verify, but this is a good start.

Resolution 10: I found that the only solution at this point, is to keep a shortcut to task manager on your desktop. Once you’ve logged in with no icons, click on the task manager go down to Windows explorer. Restart the process. Log out. And log back in. I’m hoping this is an incredibly short term fix.

Resolution 11: Ran this in PowerShell worked for me when nothing else did. Restart after or restart explorer.exe Change the two web quotes “ ” to normal quotes.
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}

Resolution 12: Restart File Explorer.

Situation: A manager attempts to create an organization-Wide Teams in Microsoft Teams but can’t.

Troubleshooting: Only global admins have the right to create a company-wide team. Have global administrator do it.

Situation: When using Barracuda Backup, you may receive an error message: The selected item :path no longer exists.

Cause: In most cases, these files are deleted but Barracuda cache hasn’t cleared them.

Resolution: Go to Backup > Schedules. Click on Edit.

Navigate to missing files or folders. Uncheck them. Reports in our example.

Click Save. You have options to keep all files with your retention policies or  Purge all.
