Hi,
we had a similar problem as well, network connection: fast start, no network: very slow
--> see http://digital.ni.com/public.nsf/allkb/9A7E2F34EC9DDEDE86257A09002A9E14 (different article)
We used the workaround with the application configurationfile placed next to the executable (=same solution as LogMAN)
because it is a very easy fix, requires zero to less additional documentation in case of a reinstall
and does not need any changes to the Internet options (or regedit, or gpedit).
(This apparantly resulted in an even faster startup of the application compared to altering the Internet options)
You can create an application configuration file:
1. Open Notepad and paste in the code below:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<runtime>
<generatePublisherEvidence enabled="false"/>
</runtime>
</configuration>
2. Save the file in the directory of the application with the name: <ApplicationName>.exe.config
3. Run the application, and the config file should disable the CLR check for the application.
