Summary

Automation Engine loses connection to container all the time.

Symptoms

Automation Engine loses connection to container all the time.

The Pilot shows the following message: "Could not retrieve the list of files".

Also, the following system error occurred:

BG_ENotADirectory: Invalid Signature.


Solution

The cause of the problems turned out to be due to new features introduced in Windows Server 2012 and SMB 3.0. The new SMB has a feature called Secure Negotiate.

This feature depends on the correct signing of error responses by all SMB v2 servers, including servers that support only protocol versions 2.0 and 2.1.

The solution is to disable the Secure Negotiate feature. To do,

  1. Open the Local Security Policy.
  2. Expand Security Settings.
  3. Look for a policy named Microsoft network client: Digitally sign communications (if server agrees).
  4. Right-click the policy and then click Properties.

  5. Select the Disabled radio button and then click OK.

  6. Close the Local Security Policy console.

The problem should now be solved.
