Judging upon the information you have already given I think there is some issue with the IP addresses you are using and/or a setting in ISA that is not correct. But before we can continue I need more information about your server and client setup.

 

In addition to the above can you tell me what laptop that is and how many network adapters it has. I would also like to know what third party software is installed on the server and the client.

The server has SBS Premium 2003 running ISA, SQL, and Exchange in a 2 NIC config.

 

Third party software on server is: 

EBM (bidding software)

EPIC (Pricing DB for EBM)

Maxwell (Accounting program)

AVG

 

Laptop is a brand new, right out of the box HP nx6110 Running WinXP Pro and Office SBE

 

NICs are: 

Broadcom 440x 10/100 Ethernet

Intel PRO/Wireless 2915ABG (Disabled)

 

Third Party Software on laptop: 

Netswitcher

AVG

Adobe

Hi Aaron,

 

Server's ipconfig is good, and the client with Admin01 is good too. The other machine simply doesn't seem to get through to the DHCP server. Can you check the cable and port where it is connected to? It hasn't been joined to the domain either yet, right?

I assume the your-a9279112e3 is the new laptop? Did you notice it does not get an IP address from the server? I would disable netswitcher if you are joining the workstation because that could well be the cause of the problems. Does the AVG antivirus on the laptop also has some Firewall build in? Many do. If so, disable that.

I checked the port and replaced the cable JIC and had the same problem. Yep, that is the computer name that HP assigned it. I just uninstalled Netswitcher and rebooted. Tried to do ConnectComputer and got "The page cannot be displayed". There is no firewall in AVG. I tried to "repair" the connection for the Ethernet card and it just sites on Renewing your IP address.

Hmmm, that sounds like a hardware problem to me. Can you try to connect the laptop to the some other router you have that does DHCP? If the laptop gets an IP address then we have to further investigate where the problem comes from. If you renew the IP address on another workstation does that work?

Do you have ISA 2004 installed and was that an upgrade from ISA 2000?

I do not have any routers. I just have two 24 port switches and two 24 port patchpanels leading to them. I renewed the IP address on my workstation just fine. I unplugged my workstation from the switch and plugged the cable from the laptop into it. I tried 2 different network cables (one brand new) and could not renew the IP address on the laptop.

 

I checked the event log and am still seeing many warnings. They are all:

 

Warning

Catagory: Packet Filter

Event ID: 15108

Description: ISA Server detected a spoof attack from Internet Protocol (IP) address 192.168.16.13. A spoof attack occurs when an IP address that is not reachable via the interface on which the packet was received. If logging for dropped packets is set, you can view details in the packet filter log.

 

This appears everey 2 - 6 seconds when the laptop is plugged in. That is the IP address of the laptop.

 

Thanks.

I just noticed that the IP Config is now different on the laptop. Here is the new one.

Can you ping the server by name? What happens if you run connectcomputer?

Can you answer this question please: Do you have ISA 2004 installed and was that an upgrade from ISA 2000?

Still getting Page cannot be displayed when trying to COnnectComputer and PING could not find host when I try that.

I have ISA Server 2004, version: 4.0.2163.213

 

I believe that this is an upgrade from 2000. I know that that we upgraded from SBS2000 premium to SBS2003 Premium.

OK. Open ISA 2004 Manager and browse to networks. In the right pane double click the Internal Network Object and choose the tab Adresses. It should show you the same as in the picture. If it does not remove the range, then choose Add Adapter and choose to add the Server Local Area Adapter.

 

I did that and it showed two ranges.

192.168.16.0 - 192.168.16.12

192.168.16.14 - 192.168.16.255

 

I removed both ranges and then added Server Local Area Adaptor and I now have three ranges.

192.168.16.0 - 192.168.16.7

192.168.16.9 - 192.168.16.11

192.168.16.13 - 192.168.16.255

 

What would cause his? Static IPs?

 

Thank you.

Aron,

 

This is strange. Can you check the DHCP server and see what scopes it has and also check the Server Local Area connector and check what IP addresses are listed there?

The only scope it whows is 192.168.16.1 - 192.168.16.254.

Server Local Area Connection shows IP Address: 192.168.16.2 with submask of 255.255.255.0

OK, strange. Instead of setting the adapter in ISA 2004 I suggest you set a range like 192.168.16.0 - 192.168.16.255 manually.

OK. Did that through ISA. Still cannot renew IP address. Rebooted.

Still cannot do ConnectComputer.

Just looked in DHCP and it shows 192.168.16.13 is leased to your-a9279112e3. Lease expires 5/9/2006 2:33:49 PM

Changed the laptops ComputerName to HPVP just in case the long, weird name caused some kind of problem, rebooted.

DHCP shows the name change with same IP address.

Still cannot rewen IP address.
