Server 2012 R2, Hyper-V VM-PDC w/ AD DS, DNS (single DC still; 2nd will be created shortly)

The Event ID 10154 General comments state:

The WinRM service failed to create the following SPNs: WSMAN/vsWBCdc01.wbc.local; WSMAN/vsWBCdc01. 

Additional Data 
The error received was 1355: %%1355.

User Action 
The SPNs can be created by an administrator using setspn.exe utility.

I worked with the setspn command. I could see "WSMAN/vsWBCdc01.wbc.local and WSMAN/vsWBCdc01" were not listed for either the administrator or the server.

I added "WSMAN/vsWBCdc01.wbc.local and WSMAN/vsWBCdc01" to the server but the error remained. I had little confidence in, but tried anyway to add them instead to the administrator account.

In both cases the 10154 EventID remains.

I guess my question is 'can I fix this error?' and 'do I need to fix this error'. Did I misread the instructions in the event viewer?

Or is this also simply a transient error that resolves after the dynamic activity of startup completes?

Your spns need to be added the service accounts, not the local administrator. ADSIEdit can be really helpful in figuring out where they go.
