Vista Businness - Remote Access and Windows Firewall issues

I was wondering if anyone could help me. I'm running Windows Vista Business
on a Virtual Machine (on VMWare's ESX)

I've got a Vista Business Virtual Machine, and i've added it to a Domain
thats being run from a Windows 2003 Domain Controller. However, i cannot
activate REMOTE ACCESS on the Vista Business VM. Each time i do, it tells me
i need to activate Windows Firewall.

However each time i attempt to activate the Windows Firewall, its not
allowed, the service will not start due to dependency issues.

Can anyone help me with activating the Windows Firewall?

Thanks!
