There are two minor changes that are worth noting when turning tracing for ESB Toolkit 2.1 on.
- In Notepad open
C:\Windows\Microsoft.NET\Framework\v4.0.30319\CONFIG\machine.config for 32-bit
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\CONFIG\machine.config for 64-bit - Locate the line with the closing configSections tag.
- Under that line paste the following section:
<system.diagnostics> <switches> <add name="BizTalkESBToolkit21" value="4"/> </switches> </system.diagnostics>
- Save and close machine.config.
- Start the DebugView program (Download)
- In DebugView, on the Capture menu, click Capture Global Win32 to make sure that it is checked.
- In the BizTalk Server Administration console, restart the BizTalkServerApplication host instance.

Another point worth noting is that there are less traces output by ESB Toolkit 2.1 in comparison with ESB Toolkit 2.0.
