Can I change the inside NIC address on my ISA2006?

Because of a minor network change, I would like to change my inside NIC address on my ISA2006.  The new address is on the same network and same subnet, with the same mask, as the old address.

The old address is not directly listed in any access or publication rule.

Are there any ramifications to this change that I should worry about?

    Yes you can do it if, as you said, it is still in the same subnet.
    You should never had used the local IP address in any rule... in ISA there's a dynamic network object that is called "Localhost" and that is made for this use, so if you find any trace of your internal IP address in any rule just change it for "LocalHost".

    I already changed ISA internal IP address many times already.
    But as far as I remember, you'll need to reboot your ISA server for this change to be entirely applied to ISA filters level.

    Have a good day.
