There is a strange thing happened to the computer with isa firewall client installed. When I restart the computer it, ip address will change to 0.0.0.0.

Anybody knows what was wrong with my network ?

Thanks in advanced,
Daniel

Hi Daniel,

Is the machine a DHCP client?

Thanks!
Tom

Hi Daniel,

I've heard of this problem, but I haven't heard of any solutions [Frown]

Hi,
Maybe it is too obviously, but I still post this.

Basic:
Address 0.0.0.0 is the address the DHCP-client have before it contact the DHCP-server for an IP-lease, and it broadcast an IP-request to ANY DHCP-server, the first who answers with an IP-address the client ussually takes.

So what I'm thinking, is that your client doesn't get an IP-address, and why not? are you sure you have free IP at your DHCP server?
But OK, since this happened when you installed ISA Client Firewall, it should have something to do with that, have you checked the bindings on your NIC? what happends if you set a static IP on the client, can you still not ping your gate way etc?

One more question, is your DHCP server on the same network segment as the client? or is the DHCP server on the other side of the ISA server (if you know what I mean?)

ISA Server IP is 10.130.20.1
DHCP Server IP is 10.130.10.20
DHCP Scope is between 10.130.100.1 - 10.130.100.254
Subnet mask is 255.255.0.0
W2K Server & W2K Workstation

If I change to static IP, I still can ping gateway, server etc.

If your DCHP server is unavailable usually the computer will automatcally assign its self a ipaddress

I've come across this issue before, I suggest trying

Ipconfig /release
ipconfig /renew
If you can't contact the dchp it should assign an ip between 169.254.0.0-169.254.255.255

or just statically assign an IP for that computer
make sure its in the same subnet of your internal network
