Situation: The client reports no one can send printer job to their label printer.

Troubleshooting: We find there is a Windows Update in the printer server.

1. Installed Windows update on all workstations.
2. Make sure the guest account on the server is enabled. Pease refer to this post:

• How to enable Guest account in Windows 10 and 11

3. If you have problem to enable Guest account, please you can add a guest account, for example visitor by following these steps:

1. Open an elevated command prompt. Here’s how:
   1. Press the key with the windows logo on it and the R key at the same time.
      This will open the “Run” box.
   2. In the “Run” box that opened up, Type “cmd” (without the quote marks) into the box next to the word open.
   3. Hold down the Ctrl and Shift keys and Press Enter at the same time.
      This will run the command as an administrator, and you will see a black window open up with a flashing command prompt.
2. Use the following commands in the elevated command prompt. You can type them yourself, or you can copy and paste them and press the Enter key afterward to execute the final command.  (If you wish to use a different name, type the commands one at a time and replace Visitor with your desired name. If it has a space in it, you have to enclose the name in quotes like this: “Guest User”).  Remember to press the “Enter” key at the end of each line to execute the commands.

net user “Visitor” /add

net localgroup Users “Visitor” /delete

net localgroup Guests “Visitor” /add

• If you want to add a password to the guest account, then type the following command as well, replacing Visitor with your Guest Account Name, and remember to replace NewPassword with the actual password you wish to use.

net user “Visitor” “NewPassword”

• When you are finished, you can close the command prompt window.

Situations: You might see some unwanted pop-up messages that appear to come from McAfee, but which don’t originate from McAfee. Here are some examples.

These messages are ‘spoofed’ (fake) messages that pretend to be from McAfee and try to make you click one of their options. If you click the options in a fake pop-up or alert, the security of your PC might be compromised. So, it’s always a best practice to read pop-ups or alert messages carefully.

The “Your McAfee expired today” pop-up message that appears in Google Chrome may be caused by a malware or an unwanted software installed on your computer. To turn off this pop-up message, you can follow these steps:

1. Open Google Chrome and click on the three dots (menu) in the upper-right corner of the window.

2. Select “Settings” from the drop-down menu.

3. Click on Extensions under Settings

4. Remove the suspected Extensions.

5. restart the browser or computer

This will reset the settings in Google Chrome to their original defaults, including any browser extensions that may be causing the pop-up message. After resetting the settings, you should no longer see the “Your McAfee expired today” pop-up message.

If the pop-up message persists, it may be a good idea to run a malware scan on your computer using your antivirus software, such as McAfee, to remove any malicious software that may be causing the issue.

There are several reasons why you may be receiving pop-up messages on your Windows 10 computer:

1. System notifications: These are notifications from the operating system, such as low battery warnings or notifications about updates.
2. Anti-virus software alerts: Your anti-virus software may send pop-up messages to alert you about potential threats on your computer.

1. Application notifications: Applications on your computer may also send pop-up messages to provide information or alert you to a new message, update, or other event.
2. Adware or malware: Pop-up messages may also be a result of adware or malware on your computer. These malicious programs can cause pop-ups and other unwanted behavior.

If you want to stop the pop-up messages, you can try the following solutions:

1. Disable system notifications: You can go to the “Settings” app and then to “System,” “Notifications & Actions,” and turn off the notifications you don’t want to see.
2. Disable anti-virus alerts: You can go to the settings or preferences of your anti-virus software and turn off the pop-up alerts.
3. Disable application notifications: You can go to the settings or preferences of the application that is sending the pop-up messages and turn off the notifications.
4. Scan for malware: If you suspect that your pop-up messages are a result of malware, you can run a full scan of your computer using your anti-virus software to detect and remove any threats.

Situation: The client has a Windows Server running as VPN server. Some users can’t establish the VPN with this Error Description: 809: The network connection between your computer and the VPN server could not be established because the remote server is not responding. This could be because one of the network devices (e.g, firewalls, NAT, routers, etc) between your computer and the remote server is not configured to allow VPN connections. Please contact your Administrator or your service provider to determine which device may be causing the problem.

Troubleshooting: As the popup error message mentions that “The network connection between your computer and the VPN server could not be established because the remote server is not responding”.

1. On the client site, check the VPN traffics and make sure there is not blocked UDP port 500, UDP port 4500 on the firewall. For example, port 500, UDP port 4500 are allowed.

2. On the server site, also make sure the VPN traffics are coming or not denied.

3. Also on the client site, trace route to check any timeout at end point.

4. Check the logs on server and client

Resolutions:

1. Check your network settings: Ensure that the network settings on your device are properly configured and that you have a stable internet connection.
2. Restart your device and the VPN server: Try restarting your device and the VPN server to see if this resolves the issue.
3. Disable third-party security software: Some third-party security software, such as antivirus or firewall programs, can interfere with VPN connections. Temporarily disabling these programs may help resolve the error.
4. Verify the VPN server address: Make sure that you are using the correct VPN server address and that it is reachable from your device.
5. Update your VPN client: Check to see if there is an updated version of your VPN client available, and if so, install it.
6. Contact your VPN provider: If none of the above steps help, contact your VPN provider for further assistance. They will be able to provide you with more specific information about the cause of the error and how to resolve it.

This error message occurs when trying to edit an attribute in the Active Directory Users and Computers snap-in on a Microsoft Windows Server. It means that the editor does not have a registered handler for the type of attribute you are trying to edit.

To resolve this issue, you can try the following steps:

1. Make sure that you have the necessary permissions to edit the attribute.
2. Check if the required schema extension has been made to support the attribute.
3. If the schema extension is not present, you may need to extend the schema and register the attribute with the proper handler.
4. If the schema extension is present, try restarting the Active Directory service or the entire server.

Resolution 2: You may need to add the attributes in order to be able to update them. This PowerShell Command will allow you to add the attributes and may prevent the error you’re seeing and therefore prevent you having to recreate the whole directory:

Set-ADGroup -Identity “test_authOrig” -Server dc.hepek.lab -Add @{authOrig=@(‘CN=TestUser,OU=User,OU=OfficeM,OU=HQ,DC=hepek,DC=lab’)}

Situation: The client has a new Comcast Business router. Wired connection works fine. However, WiFi users can’t use some apps such as Teams, Outlook. However, browsing website is no issues.

Situation: The client uses RSG VPN (in Azure) to establish the connection to the customer. It works for all office and home users except one of office users.

Troubleshooting: 1. We monitor the Palo Alto Firewall in the office, and it shows all traffics are allowed.

2. Trace router confirms it is not our system issues.
