ICS on XP Pro with Server 2003

[snoopydawg]

Hi there people. I have my main computer running XP Pro and i have a second computer with a demo of Server 2003. My connection is dial-up. My question is, does Internet connection sharing have to be inabled on both computers or just the host being my XP. The reason i ask is because i can't seem to find ICS on 2003 server. Can someone please help point me in the right direction.

Thanks,

SnoopDawg

You only need it running on the machine with the internet connetion. Depending on how you are networked I would probably connect with the XP pro machine using ICS so the connection is firewalled. This will give protection to both machines when connected. 2003 server doesnt have a firewall built in like XP sp2

It is enabled on the ICS Host only.
All other clients are set to obtain an IP address automaticly.

If you do not have two network connections on any machine, including your Windows 2003 server, you will not be presented the ICS option.

Be very careful about giving a server a dynamic IP address rather than a static one as it can cause problems if the addresses change.

I would suggest that if you have a requirement to share an internet connection you look at a better solution, maybe a broadband connection with a router enabled for DHCP instead of relying on a workstation to act as your DHCP server, for instance should that workstation be off when you want to release an ipaddress you would be assigned an APIPA one instead, this could then cause issues with clients using a leased address and those using the APIPA address.

He will not be given a choice if ICS is enabled on the server as Host. It will be a static IP.

If i have ICS enabled on XP and the two computers are networked properly, i think, then when i click on IE on server 2003, i don't get any web pages. Dunno, i think it's the IE security on server 2003, i can't seem to figure it out.

From the IP computer, do a Start, Run, CMD

ipconfig /all

and post the results back here. (You can highlight the text with your mouse. While highlighted, right click on the iconic C;\> icon at top left, Edit, Copy to make a copy of the contents into the clipboard.)

Are you using the XP workstation as the ICS Host?

If so, set the Windows 2003 computer to 'Obtain an IP address automaticly' under Network connections, properties.

Reboot.

Now from the troublesome computer, do the ipconfig /all again on that machine and repost.

Your ICS Host machine looks fine.

Now from a non-Host machine, post the information.

This entry:
Dhcp Enabled. . . . . . . . . . . : No

Tells us that a static IP has been assigned.

 

[SimonDavies]

Does the 2003 server have a fixed IP or dynamic? was it assigned an address from the ICS host?

Can you ping any outside addresses from the 2003 machine? This will tell you whether the enhanced IE security is the issue or whether it's something else. If name resolution isn't working from the cmd prompt then you either have an incorrect ip address (ie fixed) or there is a problem with the network connection.
