If I have questions regarding networking and infrastructure, where would I post such questions?
Because of being pestered and pressured into asking "the damned question" (;)), I'll state it explicitly.
I have a w2k3 server with 2 NICs, with addresses: 192.168.1.30 (LAN) & 192.168.1.32 (WAN), now, previously I was using a router which was assigning the rest of the addresses on the network using DHCP and in fact it was the default gateway to connect to the internet. The same server doubles up as a DNS and DC server on 192.168.1.30
Configuring DHCP doesn't seem to be an issue, its setting up ISA server that's proving to be a PITA. Local host can use the internet, but not any of the other computers on the network. Indeed, they can't ping any other computer, even the DNS server. Suggestions on where to start to diagnose and fix this?

I thought of that, but I thought I'd ask first, just in case.

I am not a greedy man, and would not wish to bankrupt a fellow CPian, but £100 would allow for a rather fine meal!

Probably not, mine is a server issue. Or servers rather, DHCP + ISA + Win2K3

For routing to work, they will need to be on different subnets. So the default 255.255.255.0 wont work here. Try 255.255.255.8 (or 7 or 32, or 31, heck I cant remember now!).

Can you suggest a site that can guide me on this? Google isn't being helpful by providing a zillion results

Sounds like they will be in the same subnet. That will realy mess things up.

So I should take your and Leppie's advice and split them into two different ones?

Make the first adapter 192.168.0.2 and the second 192.168.1.2 each with the subnet 255.255.255.0.
At the moment the server could be trying to get a resposne through the wrong nextwork interface and building up a queue of traffuc.

A number of things spring to mind:
1) The LAN and WAN cards should be configured into different subnets.
2) When you say you can't ping other computers, are you pinging them by name or IP address?
3) Using the router (now the other side of the firewall) to supply addresses to the internal network is going to take some work on the ISA server. I would suggest setting up a DHCP server on the internal network
4) Have you configured the computers on the LAN to use the ISA server's LAN IP as their gateway? Have you allowed the HTTP protcol from the internal network to the external network on the ISA server. Do the clients on the LAN have working name resolution for external hosts? If any of those answers is 'no', the clients won't be able to access the internet.

I got the DHCP working a while ago, and then I discovered that W2K3 can handle NAT/VPN routing all on its lonesome, so I've been busy with that. Alas, all my attempts have failed

Suggestions for the equivalent of a best practice address for the wan subnet or should I go with 10.0.0.1?

This has been resolved now that the DHCP server is working, thank you
Electron Shepherd wrote: 3) Using the router (now the other side of the firewall) to supply addresses to the internal network is going to take some work on the ISA server. I would suggest setting up a DHCP server on the internal network
I guess 2 answers this one...

I have uninstalled ISA server for the moment, I figured installing and configuring the DHCP server first would be prudent. Would it be possible to set this up using W2K3's built-in Router?

Hi, firstly please do not get the wrong idea, this is for good intentions,not spreading malicious software.
My school has over 300 computers connected to the network, and somehow they have ALL been infected with Conficker (the C edition). Unfortunately the schools IT manager recently retired and when it comes down to it I am the guy for fixing small IT problems.
We have already tried shutting down all computers and running the Microsoft Malicious Software Removal Tool (April 09 Edition) on each computer one by one. We have done this twice but obviously we are missing it somewhere and the dam virus keeps resurrecting and infects the whole network again.
My best guess is to somehow run the malicious software removal tool on all computers at once.
Does anyone know a way to copy and run a file from the server onto all networked machines?
I have full administrator access so thats no problem. Im just unsure of how to do this.
Thanks for your time in reading.
