Hi All,
We are in process of setting up a dedicated distrusted search server.
While we passed the ports (22233-22236) to network team that are required by distributed cache server. We have already set up SharePoint and configured so it's connected to farm. In turned on Distributed cache service both via Powershell as well as in Central Administration UI. We received "A failure occurred in SPDistributedCacheServiceInstance::Provision. cacheHostInfo is null for host ‘DCServer’ "error in PowerShell and in Central Administration UI it it showedError Starting. We have already conveyed this to network issue and they mentioned it's an application issue and not port issue
1. Is it really a port issue as this new DC server is not able to netstat the ports (22233-22236). Here is the SharePoint ULS Logs on Distributed Cache Server

We referred tothis URL http://www.ericjochens.com/2014/02/sharepoint-2013-distributed-cache-issues.html and author mentions that 1st issue is port and if its ports are not opened, distributed cache server may not function correctly?
2. We have 1 Application server, and 4 web front end servers. We have removed the Distributed Cache instance across servers as we have dedicated distriubuted cache server.
Will this dedicated cache server can manage all WEFs and Application server for all social workloads? How can verify if it's new service is working for all servers?
Any help would be greatly appreciated.
Thanks
Sandy
