MUVPN Users are unable to log on.

Having trouble setting up muvpn users on our new Watchguard Firebox.  I have tried contacting Watchguard tech support but they never seem to call me during an appropriate time.  Any help would be appreciated.  Here is hat I have done so far.  

Step 1:  I first setup the Authentication Server.  I am using Active Directory for authentication.  My settings are as follows:
IP Address:  100.100.100.5 (Domain controller)
Port: 389
Search Base: ou=SBSUsers,ou=Users,ou=MyBusiness,dc=miamicpas,dc=local (This is the active directory ou where all the users reside on the domain controller, SBS 2003)
Group string: memberOf
DN: blank
Password: blank
Login Attribute: sMAccountName
DeadTime: 10 minutes

Step 2:   I created a mobile user vpn group. Under VPN, Remote Users.  These are the settings that I created.
Group name is: SBSUsers
Authentication Server: Active Directory
Allowed Access: 100.100.100.0/24 (IP Scheme of internal network)
Virtual IP Address Pool: 100.100.100.125 - 100.100.100.130 (Reserved address pool for vpn users on DC)
IPSEC Settings:
Key Negotian Type: pre-shared key
Key Exp: 128000KB or 8 hours
Encr: AES (256 bit)
Auth: SHA1

At this point the mobile user vpn policy is automatically created allowing all ports open for this specific user group.  I went ahead and exported the profile o a laptop which had the muvpn software installed.  Imported the profile which was successful and tried logging on using an aircard.  I keep getting the error IKE Error phase 1, lost connection to peer.  This is where I am stuck.

I apologize with the long message, but I wanted to give all the details possible.  I hope someone can help.

Thanks,
