Q. I am using AuthentiX ISP, and the IP addresses on my machine don't show up!

A. AuthentiX ISP looks in the registry for:

HKEY_LOCAL_MACHINE 
/System
/CurrentControlSet
/Services
/* 
/Parameters
/Tcpip
/IPAddress

or

HKEY_LOCAL_MACHINE\
SYSTEM\
CurrentControlSet\
Services\
Tcpip\
Parameters\
Interfaces\
{NIC INTERFACE}
\IPAddress

this last is of type REG_MULTI_SZ and contains the list of IP Addresses configured for that network card on the machine.

Using regedt32.exe, if those registry areas do not exist, contain no IP addresses, or do not have correct read permissions for IIS, then the IP addresses will not appear in AuthentiX ISP.

For security reasons, AuthentiX ISP will only allow requests on IP addresses that it knows about.

As a workaround, you can manually create the entries AuthentiX is expecting to see.

Also, this from Bart Verbeek:

If you change the ip addresses in the registry key described above Authentix does not see them. (editing this key can be usefull if you want to assign multiple ip addresses to a single network controller)

Workaround:
After changing the ip addresses in the registry key and rebooting the machine, open the network properties --> TCP/IP --> Button Advanced...
delete one of the new ip addresses, and close all network property sheets. directly after that reopen the network properties --> TCP/IP / Button Advanced... and add the ip address which you deleted a few seconds ago.
close all network property sheets. open the Authentix Admin Program, and TADAAH there are your lost ip addresses :)

Thanks Bart!
