Configuring IP help

I want to assign a local IP to my PC running XP Pro. My wireless router
gets it's IP and DNS servers automatically from my ISP.

So I go into my network connections, right click properties on my
wireless connection and go into TCP/IP and check 'use the following IP
address'

I enter 192.168.1.70, 255.255.255.0 and 192.168.1.1. Then I leave the
DNS servers blank as my router gets them automatically.

I have this pretty much same setup in Mac OS X, where I leave the DNS
blank. Anyway, once settings are applied my machine does get it's new IP
but for some reason the connection to the internet is lost, strangely
though I'm able to get email.

Any ideas? I just want to assign an IP address to my XP machine, what am
I missing?

Why? It much simpler to use automatic IP and DNS address set up.

I'm running remote desktop clients, it's very difficult to connect to
client computers if their IP is constantly changing everytime they are
rebooted.

Why not enter the DNS servers manually? You won't get far without them.
Alternatively you may be able to tweak the DHCP in your router so it
always assigns a fixed address to each machine (determined by the MAC
address of its NIC).

If you've already made a connection (eg using DHCP initially) then Windows
might have cached the IP of the remote mail server, so will connect again
to that IP without any need of a DNS lookup. DNS problems are easily
found if one cannot ping (say) bbc.co.uk but can ping an IP such as
212.58.224.131 ( as returned when I used nslookup bbc.co.uk )

It's fairly common to either set the DNS to be the router (and thus use
the ISP-provided DNS), or to define the DNS settings along with the IP,
netmask and gateway on your wireless connection (so long as you have a
way to monitor the details supplied by the ISP to the router, typically
shown in some system log reporting the boot/connection/login process, it
will be easy enough to determine whether the IPs have changed - but ISPs
don't make changes 'too often', IME). I routinely use fixed IPs from
a couple of different ISPs and vary the servers on different PCs.

I do something similar here - I just set the DNS address to the IP Address
of my router (in XP).

Fair enough. Presumably you're using a router with VPN server
capability?

As someone else suggested: set the clients' DNS server address to the
LAN IP address of your router, the latter will/should relay DNS
requests without clients needing to know the external DNS server
address, which can also change.

Put the DNS addresses in aswell.

Fix the IP in the router configuration. Every time you reboot the router
assigns the same IP address.
