  • Unable to telnet to port 1494. Connecting to servername. Could not open a connection to host on port 1494: Connect failed. A telnet to port 2598 (default port for Session Reliability); however, might work.
  • NetStat -a does not show the server listening on port 1494.
  • A Microsoft RDP connection works.
  • The ICA listener is available and enabled.

Steps to Reproduce

  1. Run Regedit.
  2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WDICA.
  3. Export the key.
  4. Delete the key.
  5. Reboot the server.
  6. Make a custom ICA connection to the server IP address. The connection fails.


Complete the following steps to resolve the issue:

Caution! This procedure requires you to edit the registry. Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Back up the registry before you edit it.

  1. Run Regedit.
  2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services.
  3. Create a key named WDICA.
  4. Manually add the following values:
    ErrorControl: REG_DWORD : 0
    Start: REG_DWORD : 0x3
    Type: REG_DWORD : 0x1
  5. Reboot the server.
  6. After the reboot, a subkey named Enum will be created with the following values.
    0 : REG_SZ : Root\LEGACY_WDICA\0000
    Count : REG_DWORD : 0x1
    NextInstance : REG_DWORD : 0x1
  7. Make a Custom ICA Connection to the server IP address. The connection should now connect successfully.

Complete the following steps if the preceding resolution does not resolve the issue:

  1. Check for the existence of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_WDICA and its subkeys.
  2. Add permissions to the key in order to save and restore the key from a working server. When this key is manually deleted and the server is rebooted, the key should regenerate automatically.
  3. If the key does not automatically regenerate, restore a copy of this key from a known good server or manually create the entries. When replacing this key with a copy of the key from another server, navigate to the following location:
  4. Delete the data of the following value located within the above referenced key and then reboot the server:
  5. Upon reboot the data should repopulate.

Note: The cause for the disappearance or corruption of these registry keys is currently unknown.
