Cloned machines unable to register agents (4229140)

When you try to register an agent you get random error messages when attempting to register it.
In the InTrust Event log you may also get that the agent was successfully installed, but it's not appearing in the agent list.

Some of the possible error messages are:

ADC Error: Agent doesn't have an established connection to InTrust server (0x8adc2c09)
ADC Error: Virtual connection doesn't exist (0x8adc2c05)
ADC Error: Two InTrust servers are trying to process each other using agents, or temporary network address resolution problem occurred (0x8adc2c1a)
ADC Error: Connection is closed (0x8adc2c07)
ADC Error: Buffer supplied is insufficient (0x8adc2c03)
ADC Error: Invalid credentials (0x8adc2c1c)

Casue #1

 

Network issue, the traffic or ports used by InTrust could be blocked by a firewall.

 

Cause #2

 

If the AgentId GUID is identical on more than two agents this will cause problems.
This GUID is unique and is assigned to the agent when installed.

Agent.ini Example:
AgentId = "{D884F341-9495-41D9-B052-09953CC765A1}"

This is a common issue when the agent is deployed to a machine (does not need to be registered) just installed, and then that machine is copied/cloned multiple times. All PCs based on that image will have the same agent.ini and thus the same GUID.

Make sure that the computer where you perform InTrust setup has ports 900, 8340, and 8341 open for inbound traffic and not blocked by any firewalls. This is required for InTrust configuration management, agent–server communication, and repository access.

 

Also, try to manually uninstall all agents from the machines that do not appear in the agent list.

Run the following command via the command line from inside the agent directory:

It is also recommended to delete the leftover "ADCAgent" folder and registries.

 

Once all agents are uninstalled use the InTrust Manager to automatically deploy new agents.
