### Master Troubleshooting Process: Windows 2000 (All Devices Fail)

Use this Master Troubleshooting Process if none of the devices are functioning.

In many of the steps, you will be sent to another shorter procedure that you need to complete. Once you have completed the procedure, you most often will be sent back to the Master Troubleshooting Process to continue with where you left off. Otherwise, you might be directed to call Digi Technical Support.

Process

Step 1. Check the status of the PortServer. Is AC displayed on the PortServer?

> Continue with the next step. | Do the following steps: Reboot the Port Server. If AC now is displayed, go to Step 2 to verify your network connection. Go to Running PortServer Diagnostics or Running PortServer II Diagnostics. Go to Resetting PortServer.

Step 2. To verify the network connection, telnet to the PortServer.

> From the DOS root prompt, enter:

> > `telnet`

> Did you receive a PortServer login prompt?

> Go to Telnet: Receiving a Login Prompt. | You might have a network, cable or hub problem. You need to check this. Go to Telnet: Receiving No Login Prompt.

Step 3. Test the port connection from Windows 2000. Go to Testing the Port Connection: Windows 2000.

> Are the keystrokes echoed (or shown) on your screen just like you typed them?

> This verifies that the port is functional, along with the attached cable and terminal while bypassing RealPort. Your connection is good. Your device should work. If it doesn't, call Digi Technical Support. | You need to check the port parameter settings of the device attached to RealPort. Go to Checking the Port Parameter Settings: Windows 2000.
