Frequently Asked Questions

Question

What is NT Service

If a product is installed as a service, then when the machine boots up and the program is started automatically.

Customer installed the product. Some time later, restarted NT, logged on. Customer can see the IPeXchange installed as service, but neither the Internet Junction program started automatically nor the customer can invoke the program manually.

During first installation, the customer probably logged on as Administrator and second time he logged on as a user. A user does not have authority to start programs. Make sure the customer logs on as Administrator, start the service, and then he or she can log on under a different user id.

Customer is unable to install or configure TCPIP

Do the following steps:

When the machine boots up, IPeXchange does not start rather screen disappears or gives the following message:

Main:CRInit Failed. or/and Gateway not found: or/and Internet Junction Terminating.

These error message are reported because the hostname of the NT machine (gateway machine or machine you are installing IJ software) is not being resolved. This happens for example when you configure the hostname of the NT machine, but do not have a DNS entry or an LMHOSTS entry for that name. You can confirm this by opening a DOS box and try to ping to the host name (for e.g. ping NT host where NT host is the hostname of you machine)

This will fail if the hostname cannot be resolved.

Following are the steps to fix this problem:

1. Go to Contol Panel Network On top left side, you will see Computer Name. Let us call this value (V1). Note down this name. If the name contains any spaces, please change the name. No spaces allowed.
2. Go to Contol panel Network TCP/IP (installed software window) Configure Note down the TCP/IP address . Let us call this value (V2).
3. Go to Contol Panel - Network TCP/IP Configure - DNS

   On top left, you will the Host Name. Let us call this value (V3). Make sure that V1 and V3 are identical. It is case sensitive also.

4. Now open a DOS window , and create a directory called etc of the root ie: mkdir c:\etc.
5. Create a file called lmhosts in c:\etc directory. This file should have minimum one entry: TCP/IP address (V2) Name (V1/V3) and save the file.

   Example: 171.69.3.1 ijgate

6. Close the DOS window and go back to Contol Panel Network - TCP/IP ConfigureAdvanced. Select Import lmhosts. It will pop up a new window to provide path for lmhosts file.

   Input the path ie c:\etc (Do not enter the filename: ie: c:\etc\lmhosts).

   Click OK at all places. If you changed the Computer Name (V1)than reboot the machine, otherwise just restart the Internet Junction program.

When I boot my NT machine, the Internet Junction Gateway does not come up. What should I do ? Any troubleshooting tips.

1. Note down any error message on the screen.
2. Invoke Event Viewer within the Administrative Tools program group.

Some common error messages and their solution are as below:

Error Message 1:

The cisco Internet Junction service depends on the following nonexistent service:

NWSapAgent.

Go to Contol Panel - Network and check if SAP Agent is listed in the Installed Network Software. Most probably the SAP Agent is not installed. Internet Junction Gateway requires this component. Install the software by selecting SAP Agent from Add Network Software menu.

Contol Panel Network -Add Software Select SAP Agent .

Error Message 2:

The Microsoft Client Service for Netware could not start because it did not bind to any transports.
OR
The NWLink IPX/SPX Compatible Transport Protocol service failed to start due to the following error: The parameter is incorrect.
OR
The value for the Nwlnkipx parameter Export was illegal

Reinstall Client Service for Netware (Microsoft NT Workstation 3.5x) or Gateway Service for Netware (Microsoft NT Server 3.5x)

The Cisco Internet Junction service depends on the following nonexistent service: NWCWorkstation.

Install Client Service for Netware on Microsoft NT Workstation 3.5x or Gateway Service for Netware on Microsoft NT Server.

Contol Panel Network - Add Network Software

If I do not have an external router, can I use RAS to dial out to my Internet Service Provider ?

Absolutely, This way you would require only 1 IP address and in most cases,this address is provided by your Internet Service Provider.

How would I configure RAS ?

Go to Contol Panel - Network -- Add software - Remote Access Service. The detail information can be found in Microsoft manuals.

Is "dial-up on demand" available on NT ?

No, currently Windows NT provides static dial-up access. Dial-up on demand is not available yet on NT. This functionality by Microsoft is expected soon.
