This event indicates a CDM - Redirector problem. The following is a series of troubleshooting steps that can be taken in order to assist in resolving this issue:
First, find out what client device type is causing the issue (Client com port, Drive, LPT port, etc)
1. Disable all client device mappings in Citrix Connection Configuration for the ICA Listener that you connect with.
2. Logon from the client with the suspect device.
3. If you were able to logon, and no events in the Events Viewer appeared associated with CDM, re-enable one client device type at a time in Citrix Connection Configuration.
4. Repeat Steps 2 and 3 until the device type is found.
Next, Within the session, at the command prompt, type:
QOBJECT /DEVICE > QOBJECT.TXT
This command creates a text file where you can see the mapping for LPT1 and LPT2. During troubleshooting, ensure the following: The port has been mapped using the CDM redirector. This is the Citrix redirector for mapping client devices. If instead of the CDM redirector you see the LanMan redirector, it indicates that the port on the server is being mapped to another port on the server network (using Microsoft networking). In the mapping for the client device: LPTx:\yy\LPTz: LPTx is the port name at the server side, /yy/ is the session ID, and LPTz is the port on the client site, where LPTx is pointing to.
Finally, try the following if you still are having issues:
Increase the settings for the following:
RequestTimeout: Default is 60 (in seconds)
DirCacheTimeout Default is 30 seconds
CacheTimeout Default is 60 seconds
