Security issues with Windows XP using Ravlin Soft

I have just recently purchased a new computer running Windows XP Pro and I use a program called Ravlin Soft to create an IPsec tunnel to the company intranet and email server. The problem is that the program will go through Phase 1 and then will not go th
rough Phase 2 which is the authenitication mode where the password is required, instead after Phase 1 is says that security is enabled. Then the required programs will not open (Outlook or the intranet home page). I looked at the logs and it shows the co
mputer going through Pase 1 but no mention to Phase 2. Are there settings in XP that I can change or is this going to be a software issue, it worked flawless with Windows 2000.
