While registering an Enterprise Security Manager (ESM) agent to an ESM manager the registration fails with an timeout. You want to increase the timeout.
 TCP server: 2012/10/08 15:51:29:866: Connect from xxx.xxx.xxx.xxx:42547 fd=480
 TCP server: begin: 1349704289 diff: 10 end: 1349704299
 TCP server: connection handshaking failed.
csp__server_handshake: error reading version from client
timed out waiting for data from server
Some networks require more time for the communication to be succesfull.
Add the following variable to the ESM manager's System Properties:
ESM_SERVER_HANDSHAKE_READ_TIMEOUT = 60
Right-Click on "my computer" and select properties - select the Advanced tab - click "Environment Variables"
Add a variable with the name: ESM_SERVER_HANDSHAKE_READ_TIMEOUT and the value of: 60 (default value is 10s).
Step 3. Restart the "Symantec ESM Manager" service for the changes to take effect.
