We have 2 Windows 2012 R2 servers, both are running on workgroup.
We set up NLB cluster. When we open NLB Manager on the server2, then message shows "loading configuration information. Access denied. Error connecting to server1". There is no issue doing this on server1, NLB Manager is able to connect to both servers. We login using default administrator account, both account name and password are the same for 2 servers.
When we check security event log on server1, there is this strange Audit Failure log using account "test_nlb" from server2 which related to "Access denied" error. Please let us know how to resolve this. Thanks in advance.
