ISA 2006 cannot be configured by the Small Business Server tools. Those tools include:
- Configure Email and Internet Connection Wizard – yes, the “fix everything wizard” will not work.
- Remote Access Configuration Wizard
- Change IP
These tools error out as they are not configured to work against the new API set provided by the ISA team.
Bottom line is the Beta of ISA 2006 does not work on SBS 2003. More information will be posted on the Windows Small Business Server 2003 F.A.Q. later this month on how much support will be provided for ISA 2006 on SBS.
I think the Great Susan Bradley said it best when she wrote:
Repeat after me… you DO NOT install betas on computers that you care about.
