If I interpret your question correctly, do you want to have a separate version of the BTSNTSvs.exe.config file for each host instance?
So, in addition to the BizTalkServerApplication host instance, do you have YourHostInstance host instances for which you want to have a separate configuration?
I am not 100% aware that you cannot do this, but I am pretty sure that this is not possible.
I am sure this is not possible for the following reasons:
- The BTSNTSvc.exe.config file is attached to the BTSNTSvc.exe main executable file.
- , BTSNTSvc.exe.config, .
BizTalk, , - , - , .
, , , log4net, BTSNTSvc.exe.config, .
