Strange Fixed IP Problem

Hi guys.

This is a strange problem that is driving me batty.

I use Sky broadband, coming off the router I have my home PC (fixed
IP) Xbox (fixed IP) and work pc (DHCP), everything has worked fine for
2 years. I also have an IP phone.

Now, all of a sudden, my home pc and xbox (fixed IP addresses) cannot
access the net. If I set my home PC to obtain an IP address
automatically, it can connect to the web fine, but if I assign it a
fixed IP address, it cannot. It can still access the xbox ok and I
know the router is still up and running, if it wasn't then my IP phone
display would go blank. also, my work PC connects fine even when my
home PC does not.

Can anyone suggest to me why my router might have suddenly prevented
me from accessing the web when I use fixed IP addresses.

I am assuming it is the router as opposed to my PC that is causing the
problem.

Any advice would be most welcome indeed.

Regards,
Kieran

It is possible that your ISP changed their DNS server settings. When you set
your machine to use DHCP, it receives the correct DNS settings. If this is
the case, change the hard coded DNS entries (or set all your machines to use
DHCP).
