Remote Desktop Gateway Authentication Timeout Change

    Question

  • Hello,

    I am in the process of implementing RADIUS based two factor authentication for the RDS gateway.  Its a phone based 2nd factor authntication and it adds a considerable amount of time required to authenticate, sometimes up to 60-90 seconds.  However, it looks like when remote desktop client is open and says "Initiating Remote Connection..." if the user does not pick up the phone and authenticate in the next 30 seconds, the connection will time out even if the authentication was successfull.  Is there a way to change amount of time that the gateway and RDP clients are waiting for the authentication attempt to succeed?

    Our Environment:

    Windows 2008 R2 RD Gateway + ISA 2005 on Windows 2003

    Thank you.
