We are using DLP 15.0 and windows 2012 r, we create the windows cluster servers and deployed the CMS on these servers. Server are working fine but when we deploy the Agent to the client machines we are unable to see these machine on CMS managment console or in Machine Administration list in CMS. We have opend the desire ports as well. The default ports are 56099,56100,56101,56102,56098. Kindly tell me how I can troubleshoot the issue ? while deploying the agent we are not facing any kind of error. Agent installed successfully on the machine.
