These steps should only be required on Windows 10 systems that can no longer use WMDC. If you are not sure, we recommend following the manual installation instructions for any client instead of tampering with the Windows registry.<\/p>\n\n\n\n<p> If your function keys do not work as expected, be sure to confirm your emulation settings as described in the section regarding your telnet host entry. If the keys do not work after starting a new session, refer to the technical reference on keyboard maps for a list of common alternative keyboard mappings. <\/p>\n\n\n\n<h2>Basic Error Message Codes<\/h2>\n\n\n\n<p>If you don\u2019t see an emulation screen on your device, the message displayed should point to the possible causes. The following are the most common examples:<\/p>\n\n\n\n<style>\n  table {\n    border-collapse: collapse;\n    width: 100%;\n  }\n  td {\n    border: 1px solid black;\n    padding: 10px;\n  }\n  th {\n    border: 1px solid black;\n    padding: 10px;\n  }\n  .col-narrow {\n    width: 20%;\n  }\n<\/style>\n\n<table>\n  <tr>\n    <th class=\"col-narrow\">Issue\/Error<\/th>\n    <th>Solution<\/th>\n  <\/tr>\n  <tr>\n    <td>Not a Valid Windows CE Application<\/td>\n    <td>This message is typically displayed when the wrong client has been loaded on your device. Some manufacturers also include resource files that are required for the StayLinked client to run. Please confirm the client matches your hardware and device operating system. Contact support for further details.<\/td>\n  <\/tr>\n  <tr>\n    <td>Out of Range<\/td>\n    <td><div style=\"display: flex; align-items: center; gap: 10px;\">\n      <span>This message appears when the device operating system reports that it is not associated with an access point. In most cases, this means the radio has not been configured for your network. If the radio has been configured and can be contacted with a network ICMP ping, then you can set the client to ignore the association status. To disable out of range detection, scan the first barcode for the setting and then restart the client by scanning into the StayLinked client scan test.<\/span>\n      <img src=\"https:\/\/portal.staylinked.com\/sl\/kb_ev\/wp-content\/uploads\/2026\/08\/Barcode.jpg\" alt=\"always in range and restart barcodes\" style=\"width: 25%; height: auto;\">\n    <\/div><\/td>\n  <\/tr>\n  <tr>\n    <td>Error: Host Timeout<\/td>\n    <td>This message appears when the client was unable to complete the connection handshake with the server. This can be caused by entering the wrong address or port for the StayLinked server, attempting to connect to a server that is not running, incorrectly configured network or security settings, firewalls that block UDP protocol, and routing and other network-related issues. Please review the Technical Reference for Host Timeout or call support if the error persists.<\/td>\n  <\/tr>\n  <tr>\n    <td>Blank Screen<\/td>\n    <td>After the client displays the \"connected\" message, you might be presented with a blank screen if the device is reporting invalid screen dimensions or if the iSeries subsystem you are connecting to has not been started. We recommend entering fixed rows and columns for the display in the StayLinked configuration, and then contacting your iSeries administrator if you are using 5250 emulation.<\/td>\n  <\/tr>\n<\/table>\n\n\n\n<p>Once connected to the StayLinked server, the server may display several different error messages on the device. These message codes mean the device connected to the StayLinked Server just fine, but the Server cannot create a session because of the issue described with the code.<\/p>\n\n\n\n<style>\n  table {\n    border-collapse: collapse;\n    width: 100%;\n  }\n  td {\n    border: 1px solid black;\n    padding: 10px;\n  }\n  th {\n    border: 1px solid black;\n    padding: 10px;\n  }\n  .col-narrow {\n    width: 25%;\n  }\n<\/style>\n\n<table>\n  <tr>\n    <th class=\"col-narrow\">Message<\/th>\n    <th>Solution<\/th>\n  <\/tr>\n  <tr>\n    <td><strong><span style=\"text-decoration: underline;\">eSP0001<\/span><\/strong><br>No Hosts Defined<\/td>\n    <td>No Host defined in the StayLinked Administrator.<br><span style=\"display: inline-block; padding-left: 2ch;\">Use the StayLinked Administrator to define Telnet hosts.<\/span><\/td>\n  <\/tr>\n  <tr>\n    <td><strong><span style=\"text-decoration: underline;\">eSP0002<\/span><\/strong><br>Host Not Responding<\/td>\n    <td>Bad Host address or port.<br><span style=\"display: inline-block; padding-left: 2ch;\">Confirm the Host address and Telnet port information in the Telnet Host configuration.<\/span><br>Host might be unreachable on the network.<br><span style=\"display: inline-block; padding-left: 2ch;\">Confirm that the Telnet Host is currently available on the network.<\/span><\/td>\n  <\/tr>\n  <tr>\n    <td><strong><span style=\"text-decoration: underline;\">eSP0003<\/span><\/strong><br>No Keymap Found<\/td>\n    <td>This Device Type is not cross referenced to a keyboard map for this Host Emulation.<br><span style=\"display: inline-block; padding-left: 2ch;\">Use the StayLinked Administrator to add a keyboard map for this Device Type and Host Emulation combination.<br><\/span>Possible unknown Device Type.<\/td>\n  <\/tr>\n  <tr>\n    <td><span style=\"text-decoration: underline;\"><strong>eSP0004<\/strong><\/span><br>Bad License Key<br>Authentication Error<br>Admin.

When a client connects to the server with the demo key, it will display StayLinked Demonstration Mode and press any key.
