What would cause one OS X user acct. not to access the Internet?

[deckeda]

I didn't know there was much in the way of user-defined stuff where network behavior was concerned. One user could see the router just fine but no applications could access the Internet. The other user on the same Mac had no problem.

I fixed it by rebooting.

parental control?

That was going to be my guess as well.

I feel like I saw this issue once or twice as well... perhaps related to wifi passwords being stored in one user account keychain and not available to the other?

Not if a reboot fixed it.

I'd have hit the Console before rebooting.

I had a problem where an account with parental controls was completely blocked from the Internet and another time where parental controls was blocking many SSL sites. Internet filtering was not enabled. However, after Tiger*, parental controls started running all traffic through a proxy which lead to such odd behavior, even when Internet filtering was not enabled. As mentioned, a reboot did not fix the problem. I stopped using parental controls with Snow Leopard, as I had nothing but problems with parental controls in Leopard and Snow Leopard. Sometimes it works, sometimes it doesn't.

From a quick google search, there were many hits for Lion and Mountain Lion also having problems with parental controls as well.

*I could be wrong about Leopard being the earliest point to these problems, perhaps Tiger was likewise afflicted, but I do know that I personally never experienced this problem until Leopard.
