Event error 10028 may occur when ports between computers or servers are blocked. The description in your event log then shows:

Log Name: System
Source: Microsoft-Windows-DistributedCOM
Event ID: 10028
Level: Error
In my case, I was trying to manage some servers with Server Manager. These servers existed in another VLAN. But you may also encounter this error when
- you have enabled the Windows Firewall, or
- you have not enabled File and Printer sharing on the target machine
- the computer is not in your network (anymore), but the DNS record still exists
To solve this error:
- try to disable the firewall on the target computer
- enable File and Printer sharing on the target computer
- remove the computer from Server Manager (if you don’t want to monitor)
remove the server from Server manager is the solutuion
