Certificate Issue for VMWare Inventory Import

Title

Summary

When executing an VMWare Inventory discovery from Enterprise Deployment Suite running on a Windows Server 2003 SP2 or above server you may receive the following error if the VMWare instance you are querying is using a self-signed SSL certificate.

Symptoms

Failure reason:

- Failed to connect to the VMware Infrastructure server. VMware services may not be running on the machine, or may be running on a different port.

Errors:

- One or more errors were encountered while retrieving a Secure Sockets Layer (SSL) certificate from the server: Server's SSL certificate is invalid.

- In fsend call to WinHttpSendRequest: A security error occurred (12175)

- An error occured in HTTP processing

- Failed to retrieve contents from web service https://<SERVER_NAME>:443/sdk

Cause

Microsoft security update 2661254 (http://support.microsoft.com/kb/2661254) updates the minimum acceptable certificate key length to 1024 bit. VMWare self-signed certificates are 512bit and therefore will be rejected by all systems that have had this update applied.

Resolution

There are two options to resolve this issue:

A. Install and configure a 3^rd Party CA or Enterprise CA certificate 1024bit or greater on each VMWare server.

B. Configure the Enterprise Deployment Server to allow certificates less than 1024 bit.

Resolution A: Refer to your VMWare documentation as to how to install a 3^rd Party CA certificate.

Resolution B:

1. Logon to the Enterprise Deployment Suite Server with Local Administrator credentials;

2. Open a command prompt and execute:

Certutil -setreg chain\EnableWeakSignatureFlags 8

Certutil -setreg chain\WeakSignatureLogDir "c:\Temp\Under1024KeyLog"

The log directory can be locate anywhere on the server, just make sure that the folder exists before executing the command.

3. Re-execute the VMWare Inventory task to verify connectivity.
