@nimh,
I don't think that happened exactly like that. Your computers should not have had the same IP... ever. I think your problems stemmed from elsewhere.
For instance a wireless router will have an address like
186.192.1.0
and then all the rest of computers on the router will be assigned an address such that...
computer 1: 186.192.1.1
computer 2: 186.192.1.2
computer 3: 186.192.1.13
computer n: 186.192.1.(some number between 1-255)
if you run the test again, go to run >> cmd and then type "ipconfig /all" in the command prompt, you should find that your IP addresses are not the same.
There are problems with IP ban, but overall, it is an effective tool used at many sites. This problem is not unique to A2K, and this solution has worked well on other sites. This isn't
my idea, I'm just relaying the information I know that has worked on other sites.
Better than the IP ban is the hardware ban, but I admit that one is a lot more tricky and I don't personally understand the nuances very well, but it uses the computer's MAC address which is absolutely unique.
