Below is a list of common configuration problems, ordered from thin client power on to Terminal Server Login.

Contents

Powering on the Thin Client

No Power

  • Check power cable, power supply and outlets.

No Video

  • Check video cable, monitor power cable and outlets.

Booting - ACP Network Boot Loader

Cannot get IP address using DHCP

  • Is the ThinManager Ready thin client set to DHCP? They are set to DHCP by default, but can be changed.
  • Is the Thin Client on the same side of the router as the DHCP server?
  • Does the DHCP server have addresses to give out?

Cannot get IP address using Static IP menu

  • Certain models like PXE boot ThinManager Compatible thin clients cannot use static IP.
  • Static IP hasn't been set. Use the spacebar when the "Select any Key to Configure IP Settings" is displayed and set the client IP address

A Non-ThinManager Ready (PXE) Client Will Not Boot.

  • PXE-E32: TFTP open timeout
    • Using a standard DCHP server with boot options
    • Verify that there is not a firewall preventing the client from downloading the boot file
    • Verify option 67 is set to acpboot.bin
    • Check that acpboot.bin is located in the ThinManager installation directory (default of %PROGRAMFILES%\Automation Control Products\ThinManager)
  • PXE-E51: No DHCP or proxyDHCP offers were received
    • Not using a standard DHCP server: check that there is not a firewall preventing the client to connect
    • Make sure the client has a connection to the network with where the DHCP server resides
  • PXE-E52: proxy DHCP offers were received. No DHCP offers were received.
    • Verify that the standard DHCP server is functioning correctly
    • Configure the ThinManager PXE Server to not use a standard DHCP server.
  • PXE-E53: No boot filename received.
    • Using a relay agent: verify that the relay agent is configured properly
    • Using a standard DHCP server with boot options: verify that option 67 is set to acpboot.bin
  • PXE-E55: ProxyDHCP service did not reply to request on port 4011
    • Install the latest service pack for your version of ThinManager
  • PXE-E61: Media test failure, check cable
    • Make sure the client has a physical connection to the network

Cannot Load Firmware

Is Thin Client connecting to the ThinManager Server?

  • Using DHCP
    • Has Option 066 been set to the ThinManager Server IP Address?
    • Is there a link light on the network port?
    • Check router address, IP Addresses, and Subnet Mask
  • Using Static IP
    • Has the ThinManager Server IP Address been entered in the IP Configuration Menu?
    • Check router address, IP Addresses, and Subnet Mask

Is the network blocked?

  • ThinManager Ready thin client that communicate through routers, gateways, or firewalls may need some ports opened to allow data flow through these devices. See the Ports Page for a complete list of ports utilitized by ACP Products.

Loads firmware intermittently/slowly

  • Check for IP conflicts
  • Check cable connections
  • Make sure ThinManager Server CPU usage is below 100%

Thin Client Loads Firmware but fails to load configuration

"Please Define on Server"

  • Enter ThinManager and define the terminal.

"License Not Available"

  • Check your license usage in ThinManager. You are out of an ACP-supplied License.
  • The Installation ID may come from the motherboard serial number, the MAC address on the network cards, or the GUID from the operation system. Don't change or disable the network cards after licensing to prevent changing the Installation ID, which can affect the validity of the license.

"This Terminal Disabled"

  • A ThinManager administrator has disabled this terminal. Re-enable it.

"Network Error - Check Network Connections"

  • Check the network cable, link light, and network.

Was Disabled, but did not go on when re-enabled.

  • Reboot the thin client.

Is WinTMC Loaded on ThinManager Server?

  • Make sure that the WinTMC client is not installed on the ThinManager Server. The WinTMC client will try to open the 2031 port that ThinManager needs to communicate with thin clients, causing a port conflict. WinTMC is for PCs, not servers. Uninstall the WinTMC client if it is present.

Terminal Selection menu is shown, but keyboard does not work

  • Check keyboard and reboot
  • Use PS/2 splitter if the unit has only one PS/2 port
  • Switch the mouse and the keyboard if plugged into a PS/2 splitter.

Graphical ACP Logo is shown, but boot process stops

Does not attempt to connect to the terminal server

  • Check Terminal Configuration Wizard to make sure a terminal server is specified

Cannot Connect to Server xxx (0.0.0.0)

  • The terminal server doesn't have an IP address configured in the Terminal Server Configuration Wizard.
  • If using DNS, check the terminal server's registration.
  • If you are using a Citrix Published Application, you may need to specify the ICA browser.

Cannot Connect to Server xxx (w.x.y.z)

  • Check the event viewer on the terminal server. If it says "Could not issue client license", you need a Microsoft Terminal Server Client Access License (MS TS CAL) and/or a Microsoft Terminal Server Licensing server.
  • Check the Subnet Mask in the ACP Boot Loader on the thin client. If it is set to 255.255.255.255 instead of 255.255.255.0, it will fail to connect to the terminal server.

Reboot the thin client and use the spacebar when the "Select any Key to Configure IP Settings" is displayed. Change the subnet mask in the ACP Boot Loader menu.

  • Error 50 - Disconnected
  • Check the event viewer on the terminal server. If it says "Could not issue client license", you need a MS TS Cal / MS TS Licensing server.

Attempts to connect to terminal server, but dies

  • Some servers (Dell and its Dellwall.bmp, for example) load a complex bitmap background that can interfere with loading. Find the offending wallpaper file on the console session and rename it so that it doesn't load at login

Connects to connect to terminal server, but cannot login

  • Is the user a valid user? Is the password correct?
  • Does the user have permission to connect through Terminal Services (user properties in the User Manager)
  • Is the user a member of the Administrators or Remote Desktop Users Group?
  • Check the event viewer. If it says "Could not issue client license", you need a Microsoft TS Cal and or a Microsoft TS Licensing server.
  • When terminal server is in 2 domains and an administrator logs into the console with a domain account, it sets that as the default domain. If the terminals are configured to use the other domain they will be unable to login. Login to the console with the domain of the terminals to reset the default domain.
  • Is NLA turned on? Support for NLA was released with Firmware 7.1.113 found in Firmware Package 7.1.3.

Login to Terminal Server prompts for password even though the username and password are filled in ThinManager

  • The password may be entered wrong in ThinManager.
  • Always Prompt for Password may be setup and should be disabled:
    • Start > Programs > Administrative Tools > Terminal Services Configuration (2003, 2008) or Remote Desktop Session Host Configuration (2008 R2)
    • Double click on RDP-tcp Properties in the right-hand window.
    • Uncheck the Always Prompt for Password checkbox on the Login Settings tab.
      • Note: In 2012, this must be done via Group Policy or Registry Key.
      • Computer Configuration > Policies > Administrative Template > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Security > Always prompt for password upon connection change to false.
      • HKLM\Software\Policies\Microsoft\Windows NT\TerminalServices create a new 32-bit DWORD key fPromptForPassword with a value of 0.

After the session is established, it will disconnect randomly

  • Make sure each user is logging on with a unique user name. Windows will only allow one session per name by default.
  • Check the physical network connection.
  • Check for a different computer (e.g. a laptop) with the same IP address.
  • Slow down the Monitoring Interval on the Monitoring Connection page of the Terminal Configuration Wizard by increasing the timeout and retry values.

Mouse works but the application is unresponsive

Application on terminal server is locked up - kill the application and let the thin client reconnect to terminal server and restart the application.

Sound doesn't work

  • Make sure that Audio Mapping is allowed on the Client Settings of the RDP-tcp Properties in the Terminal Server Configuration Console (2003, 2008) or Remote Desktop Session Host Configuration (2008 r2).
  • Make sure that you are using a ThinManager Ready thin client that has sound capability.
  • Use the Sound Module for that specific thin client.
  • Connect a powered speaker to the "Line Out" plug. Line Out isn't amplified so it requires a powered speaker.
  • Properly working sound will play a sound at boot and at login.

The touch screen doesn't work

  • Make sure you are using the right Touch Screen Module for the touch screen controller.
  • Make sure that the serial cable is plugged into the correct serial port
  • Make sure that the Touch Screen Module is using the correct baud rate.
  • Use the USB Touch Screen Module if the touch screen is USB, or set the Connection Type to USB on the regular touch screen module.

The touch screen mouse doesn't match the touches

  • Calibrate the touch screen by highlighting the unit in the ThinManager tree and select Tools > Calibrate Touch Screen.
  • If the touches are 180 degrees out of phase, enable the "Swap XY Coordinates" parameter on the touchscreen module.

Changes to the configuration in ThinManager don't show up on the thin client

  • Restart or Reboot the thin client. Changes are only sent to a thin client at bootup.

The configuration of the primary ThinManager Server and the secondary ThinManager Server are different

  • Enable automatic synchronization by selecting Manage > ThinManager Server List or manually synchronize the configurations by selecting Manager >Synchronize in the ThinManager menu bar.

The terminals in the tree on the primary ThinManager Server show green while the terminals on the secondary are all red

  • Enable automatic synchronization by selecting Manage > ThinManager Server List or add both ThinManager Servers to the ThinManager Server Monitor List in the Terminal Configuration Wizard. Reboot the terminals and synchronize the ThinManagers as above.

The client is showing the time of the terminal server in a different time zone and not the local time

  • Use the Time Zone Redirection Module on the client with the local time zone selected.
  • Make sure that the security policy of the terminal server or domain allows it:
    • Start > Run > secpol.msc > OK
    • Expand: Computer Configuration > Administrative Templates> Windows Components > Terminal Services > Client/Server data redirection > Allow Time Zone Redirection
    • Change to Enabled

When "Terminal Servers" is highlighted in the ThinManager tree, the Details pane doesn't show OK for the connections

“No login information supplied”

  • Run the Terminal Server List Wizard and add an administrative user name and password on the Terminal Server Name page of the Terminal Server List Wizard.

“User specified does not have permission to connect”

  • This indicates that the Terminal Server had an invalid username and password added on the Terminal Server Name page of the Terminal Server List Wizard. Run the Terminal Server List Wizard and change to an administrative user name and password on the Terminal Server Name page of the Terminal Server List Wizard.
  • Use the domain in the Domain field on the Terminal Server Name page of the Terminal Server List Wizard.
  • If not in a domain, try using the terminal server name in the Domain field on the Terminal Server Name page of the Terminal Server List Wizard.

WTSAPI32.dll connection failed

  • This occurs when the terminal server is off or unreachable. Try pinging the terminal server.
  • For additional information regarding WTSAPI32.dll errors, see the DCOM_Errors Page.

The Users, Sessions, and Processes tabs don't show data for a terminal server

  • Shorten the name of the terminal.
    • Microsoft truncates the terminal names to 15 characters. The Process information won't display for terminals with a name longer than 15 characters.

The Users and Sessions tabs show data for a terminal server, but the Processes tabs shows no data

  • Shorten the name of the terminal.
    • Microsoft truncates the terminal names to 15 characters. The Process information won't display for terminals with a name longer than 15 characters.

When shadowing a client the mouse doesn't work in the shadowed session

  • The user must be logged into the shadowing computer as an administrator, or as a ThinManager Administrator, or member of a security group that is given permission to use interactive shadowing in the ThinManager Server Configuration Wizard.
  • The interactive shadow must be checked in RemoteView on the ThinManager menu.
  • A terminal using the Share Keyboard and Mouse module will only be interactive if the mouse is active in that session.
