Cannot connect to WSUS console after changing administrator password

We had to change our domain administrator password and now I cannot connect to my Windows Update server from the WSUS Console.  The Windows Update Server is running Windows Server 2012R2 Standard.  Can someone tell me how to reset/change the password in WSUS, so I can connect to the server again from the console?

Check you IIS logs

this is an article for windows 2008

WSUS does not have a account or password it uses IIS and port assignments to gain access to the administrative console.

check your IIs setting

Any event errors ?

Thank you trgrassijr55 for the information.  

Below are the steps I took to resolve:

Open IIS Manager
Browse to Sites/WSUS Administration
Right Clicked WSUS Administration
Go under Manage Website/Advanced Settings
Selected Physical Path Credentials
Clicked box with 3 dots
Clicked the Select button
Typed in username (including domain name) and new password
Clicked OK twice
Right Clicked WSUS Administration
Chose Manage Website and Restart

After this I was able to connect to the server in WSUS Console on the server.  I apologize if this is too much detail.
