Today, during an analysis of an old BizTalk Server 2016 environment to be able to migrate with as-is configurations to BizTalk Server 2020, I found an error that I had never encountered before:
TITLE: Microsoft BizTalk Server Configuration Wizard
Either or both of the hosts (inproc: BizTalkServerApplication, isolated:BizTalkServerIsolatedHost) created during BizTalk Runtime configuration could not be found. To workaround, please re-create the hosts.
This error occurred on the BizTalk Server Configuration console when we selected the BizTalk Runtime option from the three available options.
Cause
The error message details the cause very precisely: Either or both of the hosts (inproc: BizTalkServerApplication, isolated:BizTalkServerIsolatedHost) created during BizTalk Runtime configuration could not be found.
It is not common to get this error message because most clients do not delete the default host instances created during the installation process. Instead, they use them. But if you delete the default host instances, you will get this error message.
It does not affect the BizTalk runtime; it will work properly, but we will not be able to use the BizTalk Server Configuration Console to extract or see the environment’s BizTalk Runtime configuration.
Recommendation: Do not delete the default host instances from your environment.
Solution
The error message details the cause very precisely in the solution as well: To work around this, please re-create the hosts.
I do think that you only need to create the hosts. The host instances will be optional. But my recommendation will be:
- Create the missing Hosts.
- Create a host instance for those missing Hosts.
After we create those hosts and host instances, this problem will be solved, and you can consult all the options or extract the configuration on the BizTalk Server Configuration Console.
I hope you find this helpful! If you liked the content or found it useful and want to help me write more, you can buy (or help me buy) my son a Star Wars Lego!
