Issue resolved by following resolution step,

Give the Local Administrator Group on Second Host Remote Launch and Remote Activation permissions in dcomcnfg.

On Second Host  Open Elevated Command Prompt  Then type “dcomcnfg”  Expand Component Services  Click on Computers  Right-click My Computer  Properties Under COM Security  click "Edit Limits" for both sections.  Give remote access, remote launch, and remote activation for Local Administrator Group.

Thank you.

Is this machines are part of workgroup or domain?

If its part of workgroup, then ensure that you will keep admin user/password same on both nodes.

Also if this is unicast NLB, ensure that you have 2nd adapter installed on both nodes, otherwise the behavior is expected
Because in Unicast original MAC Addess is overlapped by virtual one, hence you need 2nd NIC to connectivity between NLB nodes
