Hi, Does anyone experience problems connecting Vista Build 5744 VPN to ISA Server 2004? Both L2TP/IPsec (Preshared key and Certificate) gives me problems as well as PPTP... With Windows XP SP2 everything works, and Vista Build 5600 (RC1) works well... I did some Netmon 3.0 on the box, and saw that ESP never began on Vista Build 5744 (It only gets ISAKMP done) The test was done from an internal client to the internal interface on the ISA Server... if you like to test Vista VPN against ISA Server 2004, and provide some feedback on this, please let me know (I have a test account to a closed test lab) Thanks Jesper Hanno
