RDS Session Host asking for Smart Card

I set up an RDS farm with gateway/rd web and has been working fine

I've gone to demo it and when logging into the session host(2012R2) it is now asking to insert a smartcard

I have done some troubleshooting that others have suggested but no luck?

Interactive logon-> Require Smart card is set to disabled local GPO

Smart Card Enumeration service is set to disabled

On the gateway login type has been set to 0 (password NTLM)

Any ideas?

Thanks
