Hello, I have a lot of assets which shows this scan issue:

Scanning Access denied - possible causes:.
Scanning credential is missing administrative privileges on KESC-EP.
Username/password incorrect for: NNTN Login Credentials (.\WIN-06C8SOK6DMF), G4L (.\Administrator)

How to resolve it?

Hello there!

As Lansweeper pulls most Windows computer data from WMI (Windows Management Instrumentation) and WMI data is, by default, sent over random ports, we recommend checking your firewall settings whether anything is blocking WMI traffic. If you are using Windows Firewall, you can find additional information and instructions on how to configure the firewall in this knowledgebase article: https://www.lansweeper.com/knowledgebase/firewall/. For other firewalls, you will need to consult your firewall documentation.

Other things you can try/check while further troubleshooting these errors: 

• Double-check whether your scanning credentials are set up correctly and are linked to the correct scanning ranges. In addition, make sure these credentials have sufficient (administrative) privileges on the machine. General information on creating and mapping scanning credentials can be found here: https://www.lansweeper.com/knowledgebase/creating-and-mapping-scanning-credentials/ 
• Try running the following script on the client machine (as administrator). It will reconfigure DCOM and some other settings. DCOM is used to establish the initial connection to the client machine and could also cause RPC errors.
• Checking the troubleshooting steps in https://www.lansweeper.com/knowledgebase/wmi-access-is-denied/ on access denied errors and https://www.lansweeper.com/knowledgebase/the-rpc-server-is-unavailable/ on RPC errors as well. 

Additionally, we have received a number of similar reports from customers where scanning credentials suddenly stop working for Windows assets. We suspect it is related to DCOM security hardening, which is now enabled by default. Please check out this Quick Tech Solution post on our community forum for more information:
