I thought I would add this here in case anyone searches for this problem...
When using Connect-VIServer on a machine that is in the same domain as the vCenter Server it should pass my logged on credentials in.
VC is in domain and I can log into the web client with my domain credentials. The machine I am on is in the same domain
Connect-VIServer VC01
--> Prompts me for creds when it should pass through my creds
Connect-VIServer VC01 -Username corp\administrator -password VMware1!
--> Using the same credentials as i am logged into the machine as connects fine
This is a configuration issue with vCenter mentioned in this KB article which offers a solution that worked in our environment:

After applying the config change we got it working, a tip is to always enable verbose mode for this cmdlet as it gives a lot of information.
