Re: can't ping gateway IP address

Hi Terence,

I have emailed the information. ran CEICW - problem not solved. I removed
all ranges for internal adapter except our 192.168.16.0 range, but that did
not solve the problem. Followed your additional instructions, but got errors
during the Isatools process. Cab file is on its way.

The key issue that I was trying to focus on is the inability to ping the
router/gateway at 10.0.0.138. Not sure if the 14147 error is related.

Hello James,

Thank you for posting here. Let's also thank Cris for the input.

From the description, I understand that the domain users unable access
Internet and you receive event 14147 on the SBS Server about ISA 2004. If I
am off base, please do let me know.

The Internet access issue may cause by the 14147 error. Let's focus on this
error.

This issue occurs if the ISA Server network objects do not match the
routing table entries that ISA Server uses to understand the network
topology. I suggest you perform the following steps:

1. Run the CEICW. The CEICW will help you to configure the network settings
on SBS:
Please open SBS server management console, navigate to 'To Do List'. Click
'Connect to the internet' in the right panel. Follow the wizard to
configure the networking settings.

More info:
825763 How to configure Internet access in Windows Small Business Server
2003
http://support.microsoft.com/?id=825763

2. Please try to manually recreate the ISA Server internal network IP range
to see if the problem can be resolved:

a. Open ISA management console, navigate to
Servername\Configuration\Networks, on the "Networks" pane, and double click
Internal.

b. Go to the Addresses tab, remove the existed address range.

c. Click the Add Adapter button, and add your internal network adapter
(Server Local Area Connection)

d. Then confirm only the address range of your internal network will be
listed. And ensure
10.0.0.2-10.255.255.255;169.254.0.0-169.254.255.255;172.31.255.255;192.168.0
.0-192.168.15.255;192.168.17.0-192.168.255.255 which lists in the error
massage does not apply here.

e. Click the Apply button to save the changes.

3. If you have multiple subnets in your network, you may also refer to this
KB document for resolution:

Client computers cannot access external resources, and event ID 14147
appears in the Application log in ISA Server 2004 (884496)
http://support.microsoft.com/default.aspx?scid=KB;EN-US;884496

If we cannot resolve the issue after we perform the above steps, please
help me collect some information for further investigation:

1. Please help to gather the ISA Info:

1) Download the file from the following URL:

http://www.isatools.org/tools/isainfo.zip

2) Extract all files to a folder on ISA server.

3) Double click Isainfo.js. This will generate 2 files
ISAInfo2004-<computer-name>.log and ISAInfo2004-<computer-name>.xml in the
current folder.

4) Please send these files to me at v-terliu@xxxxxxxxxxxxx

2. Gather MPS network report on SBS:

a. Download MPSrepot_network from
http://download.microsoft.com/download/b/b/1/bb139fcb-4aac-4fe5-a579-30b0bd9
15706/MPSRPT_NETWORK.EXE

b. Run MPSRPT_NETWORK.exe on the server box.

c. The tool will automatically collect the information. This procedure will
take 10~15 minutes.

d. Open Windows Explorer, navigate to the folder:
%SystemRoot%\MPSReports\Network\Reports\Cab\

e. Send the .cab file directly to me at v-terliu@xxxxxxxxxxxxx

Hope the above info helps. Please feel free to let me know if anything is
unclear.

Thank you and have a nice day!

Best regards,

Terence Liu(MSFT)
