Cisco Cisco Agent Desktop 9.0 技术参考

cleared, then Terminal Services sees the agent as logged in. This can 
happen if the agent does not log off of Terminal Services cleanly after 
logging out of CAD. To log out cleanly, the agent must select Log Out 
from the Terminal Services dialog box drop-down list and then click OK.

An agent logs into Agent Desktop as a mobile agent on one computer 
and closes Agent Desktop while on a call, and then attempts to log into 
another instance of Agent Desktop on another computer using the 
same agent ID but a diffrerent extension. A forced login does not work

The agent must log out of the first instance of Agent Desktop that was 
started. If this does not work, reset the phone through CallManager and 
the CAD Services reset.

When agents start Agent Desktop, they see the following error: “A 
licensing error has occurred. Please try again in five minutes. If the 
problem persists, please see your log file or the System Administrator 
for details”

Conditions: Telnet tests from the agent PC to the LRM service on the 
CAD server (port 65432) fail. The LRM service is running and agents 
are able to connect some of the time. Cisco Security Agent (CSA) is 
installed and running on the CAD server.

CSA log reports the following: “Event: Possible SYN Flood detected. 
Source addresses include 10.X.X.X. TCP ports, including port 59004, 
SYN Flood protection has been enabled.”

Cause: CSA is in SYN Flood detection mode. Agent PCs have the 
firewall enabled and are blocking packets, and CSA thinks the PC is 
non-responsive.

Short-term solution: Restart CSA on the CAD servers. 

Long term solution options include: 

■

Option 1: Leave the systems as is. Risk: SYN Flood detection 

mode might become enabled, which can prevent agents from 
logging in. If not discovered immediately, the problem can persist 
until SYN Florrd turns off by itself (approximately 2 hours). 

■

Option 2: Turn off SYN Flood detection mode. Risk: Leaves the 

server open to SYN Flood.
