Hi!. I just wanted to know if you configure a PPTP VPN that I can have security flaws. Would publish with ISA Server 2006

Hi Jose, Not sure what you are are asking. If you combine PPTP with EAP/TLS authentication (using smart cards), there really are no security flaws for PPTP. Most of the previous flaws related to poor passwords in combination with weaker forms of password encryption (CHAP). If you are using username/password, then you want to support a minimum of MSCHAPv2 Brian
