Apache not working after Boot Camp setup

Hi,

I've just finished setting up Boot Camp (XP SP3 on a NTFS partition). In the end it worked OK.

Returning to OS X, my Apache/PHP setup is no longer working for some reason. It has been working great since day 1 I set it up (appx. 1,5 years back).

I've tried restarting Apache as well as turning Web Sharing off and on, but no luck. I have also tried rebooting.

I have not setup IIS in XP - but I guess it's not related to this anyway.

Anyway, what could be the reason for this? Web Sharing tells me that my personal website is http://mbp.lan/~peter/, but this and http://localhost/~peter/ don't work.

Any help much appreciated.

Thank you.
