EMS - WinRM client received an HTTP status code of 307

We're getting the following error when trying to use the Exchange Management Shell. Everything else appears to be working perfectly fine. 

New-PSSession : [$SERVER] Connecting to remote server $SERVER failed with the
following error message : The WinRM client received an HTTP status code of 307 from the remote WS-Management service.

There seems to be very few articles relating to a 307 response. We've tried a few things but have gotten nowhere. EMC web interface still works and has no issue that we've come across yet. We're beginning to think that the several other IIS websites we have hosted on this machine (Mostly on port 80, but all bound to specific host names) has something to do with the issue however the server ran fine for months before with extra websites. Even then, none of the other websites have a 307 configured...

Help would be appreciated!

Cheers,
