Hi Alessandro,
Welcome to Microsoft Community.
I'm Hahn and I'm here to help you with your concern.
The error message you're encountering, "The print spooler failed to reopen an existing printer connection because it could not read the configuration information from the registry key," suggests that there might be an issue with the registry key related to printer connections on your Windows Server 2012 R2 system.
Here are some steps you can take to resolve the problem:
- Restart the Print Spooler Service:
- Open the Services management console by pressing
Win + R
, typingservices.msc
, and hitting Enter. - Locate the "Print Spooler" service in the list.
- Right-click on it and select "Restart." Alternatively, you can stop and then start the service.
- Open the Services management console by pressing
- Check Registry Key Permissions:
- The error message suggests a problem with a specific registry key. You may want to check the permissions on this registry key to ensure that they are correctly configured.
- Open the Registry Editor by pressing
Win + R
, typingregedit
, and hitting Enter. - Navigate to the registry key mentioned in the error message, which is likely something like
HKEY_USERS\S-1-5-21-1528231074-3849690144-2975117709-1013\Printers\Connections
. - Right-click on the "Connections" key, select "Permissions," and ensure that the necessary users or groups have appropriate permissions. The "SYSTEM" and the user account used for RDP should have full control over the key.
- Recreate the Printer Connections:
- In some cases, the printer connections might be corrupted. You can try to delete the printer connections and recreate them.
- On the server, remove the existing printer connections by going to "Devices and Printers" and deleting any problematic printers.
- Re-create the printer connections by adding the printers again, ensuring that they are properly shared.
- Check for Third-Party Software Conflicts:
- Third-party software, such as security or printing management software, can sometimes interfere with the print spooler. Try disabling or uninstalling any such software temporarily to see if it resolves the issue.
Disclaimer: Temporarily turn off antivirus protection. However, keep in mind that if you do so, your device may be vulnerable to threats. So please turn it on immediately once issue fixed.
- Check for Corrupted Printer Drivers:
- Corrupted or incompatible printer drivers can also cause issues. Make sure you're using the latest printer drivers and consider reinstalling the drivers for the affected printers.
Always be cautious when making changes to the Windows Registry, as improper edits can cause further problems. It's recommended to back up the registry before making any changes.
If the issue persists, you may need to restore the registry key from a backup or reinstall the printer drivers. I hope this helps! Let me know if you have any further questions.
Your Sincerely
