If connecting through the WLAN option (and not through ATT) for access on
the business LAN, then Proxy (ISA) is restricting the account. If ISA is
setup to allow based on authorized access, meaning that he must log in or be
logged on to a Windows machine, and ISA uses Windows Authentication, then it
appears he's not logged on to the ISA with his SBS account (using the iPhone
WLAN access), then ISA will restrict access. I don't remember how or if
possible to configure proxy credentials on an iPhone. Is there an option to
Do you have ISA setup to restrict based on credentials, or IP address or
both? If both, and the AP has its own subnet, is the AP subnet defined as an
internal subnet? If you use a laptop on the AP, does the site work?
Does the wireless AP have its own DHCP service (giving out it's own IP
addresses on a subnet different than the business LAN), or is the wireless
AP set it 'corporate mode' (that gets an IP from SBS DHCP)?
