3. Create an environment variable (if you don't know how, click here)Name: CNTLM_HOME
   
   Value: C:\dev\Cntlm (it's only an example, choose your destination's folder)
4. Add to the PATH this new variable CNTLM_HOME (if you don't know how, click here)
5. Take a backup of the original configuration file %CNTLM_HOME%\cntlm.ini => cntlm.ini.default
6. Remplace the content of the file in %CNTLM_HOME%\cntlm.ini by...
   # Cntlm Authentication Proxy Configuration

   Username testuser

   Domain corp-uk

   
   

   # List of parent proxies to use. More proxies can be defined

   # one per line in format <proxy_ip>:<proxy_port>

   Proxy proxy-name:8080

   
   

   # List addresses you do not want to pass to parent proxies

   # * and ? wildcards can be used

   NoProxy localhost, 127.0.0.*, 10.*, 192.168.*

   
   

   # Specify the port cntlm will listen on

   # You can bind cntlm to specific interface by specifying

   # the appropriate IP address also in format <local_ip>:<local_port>

   # Cntlm listens on 127.0.0.1:3128 by default
