can't make any secure connections

[wmmk]

Safari won't let me log into paypal or mobileme (gives an error msg. about "secure connections"), Apple Mail isn't working, and a message has been popping up and telling me that my IP address on my network is already being used.


What might be going on?

Thanks much,
wmmk

Well, are there other machines on your network? It's very possible the machine is trying to user another machine's IP address. Also, provide more details about the error messages, both their phrasing and when they occur.
