Hi Mahesh,
From the provided error log snippet, seems there is some configuration issue in the config.xml, present on the agent server. Could you please provide us the config.xml in a private message from the agent server for the review.
By default, this config.xml will be located at below location, if you have changed the default location then provide the file from the changed location.
%ProgramData%\AppDynamics\DotNetAgent\Config\config.xml
We will review the config.xml and update you the findings.
Thanks,
Ashish.

Do you already have a Server Visibility agent or other agent running on this machine? I found that with the server visibility agent running prior to the .NET agent I had to entirely disable the Machine Agent Service before attempting to connect to our controller in the .NET setup. However, my error message appeared to be stating that there was a conflict in the "monitoring services" and to verify if there was a previously installed service for monitoring.
If that is not the problem, attempt to telnet using the following to verify you're allowed the network to network connectivity. (In CMD line on Windows) type "telnet CONTROLLERip CONTROLLERport" and if you cannot connect, you're dealing with a network issue. The only reason I think perhaps this is a network issue or conflicting agents is that the config for 1 agent should work fine for the next if your network settings are identical.
Please also review what version the agent you've copied the configuration from is on. If the agent that you are deploying is not on the same version you could be attempting to start your agent without hte necessary conifugrations and flags available and configured.
