    Hey,

    I used system restore (in windows 7) and found that the time zone was messed up (in leopard) and also I can't connect to the internet with leopard (both firefox and safari). I'm typing this in windows 7 on the same mac. Could the leopard ethernet driver be deleted during system restore in windows 7? (I'm assuming the drivers are the same in both bootcamp and leopard (is it?)...but that cant explain why I can still connect to the internet with windows 7 on the same machine) Anyone ran into a similar problem with xp or vista?

    If you used system restore to take it back before you installed the BC drivers from the Leopard DVD, it can delete the drivers.

    But, no, OS X and W7 don't use the same drivers. W7 cannot change anything on the OS X side.

    but how did I lose the internet connection on the leopard side? I didn't change any settings on leopard. Is there any quick fix for this? (besides reformating my mac?)

    BootCamp sets up a virtual BIOS, as Mac's are running with EFI firmware. This allows you to boot a non-EFI aware OS from a separate partition. So when you boot Windows, (via BootCamp), it's completely separate. Windows won't be able to read the Leopard partition. Totally separate.

    Your issue sounds like it's related to a network problem. Your router may have spoofing protection and does not like a different OS using the same MAC address as what is saw online earlier. Did you have an IP dished out when you were in Leopard?

    Don't reformat your Mac. That's not where the issue is. That's like saying "I'm not getting mail delivered so I'll tear down the house and build a new one"

    Not too sure because I live on campus and I don't have access to those information. But my time zone was changed as well (original time - 5hrs)... how did that happened?

    BC has been known to not hold the time zone info all that well, since Windows doesn't actually have access to the system clock while powered down.

    That's a different issue. Windows does not use UTC by default and changes the hardware clock to suit. To fix the time issue, you'll need to fix Windows by altering the following registry setting:

    Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation]
    "RealTimeIsUniversal"=dword:00000001

    I meant time zone was changed on the leopard side after system restore on win 7 side. (sorry about the miscommunication)

    That's not right, there is something else going on here.

    Yes, I understood that. Ok, I'll explain...

    By default Leopard will use your internet connection to contact an NTP (Network Time Provider) commonly called a time server. When/if it finds one, it requests the time based on UTC/GMT and will update the OS and then update the hardware clock.

    Then you boot into Windows, and it will do something similar, query a time provider, however it will set the hardware clock based on localtime not on UTC. When you boot back into Leopard, you will see the clock is wrong, however if you give it enough time, an update will occur and Leopard will change the clock back to the correct time.

    The problem is that Windows does NOT interpret the time base correctly. So Windows needs to be corrected.

    The UTC issue he is talking about is what I have posted the registry fix for.

    As for his being unable to surf the net via Leopard is another issue again, so you're right, there is something else going on, separate to this time woes.
