Distributed Cache service Issue

Question

In our Farm we have 2 wfe server and 1 app server. I installed sharepoint farm .firewall is disabled in all servers. i didn't create any web application nor configured any services in farm. I only stopped the 'distributed cache service' in App server but it continued running on WFE1 and WFE2 server. my both  WFE server are on VM and the assigned RAM is of 25 GB on each server.

when I run powershell command Get-CacheHost on WFE1 server, the result was:

WFE1.domain.com:22233   AppFabricCachingService UP             3 [3,3][1,3]
WFE2.domain.com:22233   AppFabricCachingService  Unknown             0 [0,0][0,0]

App.domain.com:22233  AppFabricCachingService  Down            3 [3,3][1,3]

when I run powershell command Get-CacheHost on WFE2 server, the result was:

WFE1.domain.com:22233   AppFabricCachingService Unknown          0 [0,0][0,0]  
WFE2.domain.com:22233   AppFabricCachingService  UP             3 [3,3][1,3]

App.domain.com:22233  AppFabricCachingService  Down            3 [3,3][1,3]

I have removed and added again the 'distributed cache service' on both WFE servers, but the results were same throughout (as shown above).

Request help with following issues:

  

1) how to solve this issue?

2) Is it possible that this issue will have impact on office web app?

3) Is it possible that this issue will have impact on Microsoft NLB?

Thanks in advance
