Hi
This problem may be caused by a NetBIOS name conflict between the workstation and either another workstation with the same NetBIOS name, or a workgroup or domain with the same NetBIOS name as the workstation.
Computers must have unique names on the network. To fix the issue, I would have you rename the computer and see if it fixes the issue.
You must be logged on as an administrator to complete these steps.
Right click Start, click Control Panel, click System, and then click Change Settings under Computer name, domain, and workgroup.
Click Change Computer Name, type the new computer name, and then click OK.
If the issue persists, you may stop and restart the computer browser service and check if it helps.
Here are the steps:
Press Windows Key + R to open the Run prompt.
Type services.msc and hit enter.
Find Computer Browser in the list, right click on it and select the properties.
Click on the Stop button, restart the computer and now restart the service by clicking on Start.
