HKLM\SYSTEM\CurrentControlSet\Services\NlaSvc\Parameters\Internet

Change or add the following keys as indicated:

ActiveDnsProbeContent = 8.8.4.4
ActiveDnsProbeContentV6 = 2001:4860:4860::8844
ActiveDnsProbeHost = dns.google
ActiveDnsProbeHostV6 = dns.google
ActiveWebProbeHostV6 = www.msftconnecttest.com
EnableActiveProbing = 1

Then either restart the computer or disable/enable the network adapter.

We experienced this on a machine that had just installed some updates. The cause was the dependent Base Filtering Engine service hanging when trying to start.

1. Fix the BFE Service Registry Keys:
   Windows 7  |  Windows 8  |  Windows 10  | Windows 11
   
2. HKLM\SYSTEM\CurrentControlSet\Services\BFE\Parameters\Policy
   Change the permissions on the Policy key
   Add NT SERVICE\BFE
   Advanced permissions – Allow:
   - Query Value
   - Set Value
   - Create Subkey
   - Enumerate Subkeys
   - Notify
3. Select Replace all child object permissions with inheritable permissions from this object
4. Restarting Windows may be required

If still not good, try resetting the BFE service permissions / security descriptors in an elevated command prompt.

When a client attempts to connect to a VPN host, it fails with “A connection to the remote computer could not be established. You might need to change the network settings for this connection.”

In Device Manager:

1. Uninstall all adapters starting with “WAN Miniport” by right-clicking each > Uninstall
2. At the top of the Device Manager tree, right-click the computer name > Scan for Hardware Changes. The adapters removed in step 1 will reinstall automatically without restarting

When recovering data from a failing drive that is slow to read, you will get the occasional “You don’t currently have permission to access this folder. Click Continue to permanently get access to this folder” block that may never (or take forever to) finish.

You can avoid this by using an elevated instance of Explorer. However, the only option in Task Manager is to restart the Windows Explorer process so it’s impossible from a command prompt.

The solution is to perform the following commands from within an elevated session of PowerShell:

taskkill /f /FI "USERNAME eq $env:UserName"/im explorer.exe
c:\windows\explorer.exe /nouaccheck

A client RDP machine running Windows 11 may get stuck on “Estimating connection Quality” when connecting to some servers that are not up to date. To fix, add:

HKLM\Software\Policies\Microsoft\Windows NT\Terminal Service\Client

Add DWORD (32bit)

fClientDisableUDP  = 1

No need to restart the computer but kill stuck background Remote Desktop processes before trying it again. The previously-stuck sessions continue to run even if you close the RDP when it’s stuck on “Estimating connection Quality.”

We have had a few cases where an older version of Outlook was updated to Outlook 2019 or later to accommodate modern authentication. It would work for a while then the user would begin getting repeatedly prompted for their password because it stopped using modern authentication.

For some reason, the following registry entries were either missing or changed. Changing/adding them resolved the issue:

HKCU\SOFTWARE\Microsoft\Office\xx\Common\Identity\EnableADAL
REG_DWORD    1

HKCU\SOFTWARE\Microsoft\Office\xx\Common\Identity\Version
REG_DWORD    1

HKCU\SOFTWARE\Microsoft\Office\xx\Common\Identity\DisableADALatopWAMOverride
REG_DWORD    1

HKCU\SOFTWARE\Microsoft\Office\xx\Common\Identity\DisableAADWAM
REG_DWORD    1

HKCU\Software\Microsoft\Exchange\AlwaysUseMSOAuthForAutoDiscover
REG_DWORD    1

Later versions of Outlook do not have the ability to create a profile without a working email address. Such profiles are commonly used when Outlook is being used only to open PST files that have been created as archives.

Running this command will create such a profile:

Outlook.exe /PIM <profile name>

So, to create a new profile called “snapshot”:

Outlook.exe /PIM snapshot

Remember that Outlook’s search index will have to be built for the data file(s) associated with this new profile so the search function will be limited at first.

The shortcuts located at the bottom of the folder list in Outlook 365 (Mail, Calendar, People, Notes, etc.,) moves to a narrow vertical bar on the left with some of the shortcuts, such as Notes and Folders, missing.

For now, the only fix I have found is a registry entry:

HKCU\Software\Microsoft\Office\16.0\Common\ExperimentEcs\Overrides

Add/change 32-bit Dword:

Microsoft.Office.Outlook.Hub.HubBarcollapsible = 0

Workgroup printers stop working after Windows Update for RPC exploit (KB5005565.) Attempts to reconnect give error 0x0000011b

This can be resolved by adding/changing this registry entry:

HKLM\System\CurrentControlSet\Control\Print

Add DWORD RpcAuthnLevelPrivacyEnabled = 0

Then restart the Print Spooler service

This known issue was corrected by Microsoft on 2/24/2022.

1. Close Outlook
2. In REGEDIT, browse to HKCU\Software\Microsoft\Office\16.0\Outlook\Profiles
3. Locate the Outlook Profile name of the profile that the shared mailbox is not updating and select it.
4. In Registry Editor choose Edit, Find, and search for registry key name:  0102663e
5. Locate this key in the profile where the parent key is just above the GroupStore as shown below:
   
6. Right click on key name: 0102663e and select Delete.
7. Close Registry Editor and restart Outlook.

It will take a minute or so for the sync to re-establish.
