Cause
In the machine.config, under system.transactions section, distributedTransactionManagerName is set to the value which is not a valid server name
<system.transactions>
<machineSettings maxTimeout="02:00:00" />
<defaultSettings distributedTransactionManagerName="someserver" timeout="02:00:00" />
</system.transactions>
Resolution
We've removed the <system.transactions> section from machine.config to resolve the issue
Note:
1) This configuration can be present in global web.config or application’s web.config as well. If you are running into this issue and did not find the <system.transactions>configuration in machine.config, please also verify global web.config, application’s web.config, etc.
2) In this particular case, we’ve got the issue in BizTalk environment. However this article applies to all DTC related applications which are using system.transactions.
