I have some oddball issues in my event log and some of them appear to be related to inter-communication (intra?) between members of the farm. I worked on another farm several months ago and had to enable port 80 on all machines and use PowerShell to enable HTTP ping. I believe this was in support of Request Management. So...on the farm I am helping to rehab now I see that the previous admin disabled port 80 on the App Servers. This means that HTTP Ping works from App to WFE but not from WFE back to App.

Do you have the web application service running in the APP server? It is a good practice to enable port 80 and 443 in all the SharePoint servers in the farm.

Hi,

As I understand, you want to know if the IIS should be running on ALL SharePoint servers and listening on port 80 for HTTP Ping in SharePoint 2013.

In addition to thk_04, there is a list of ports used in SharePoint 2013 and its related services in the articles below.

The article below is about TCP/IP Ports of SharePoint 2013.

I'm sorry but this does not answer the question, especially for SharePoint 2013. There is the concept of an HTTP Ping between servers for some reason I am not totally familiar with. I do sometimes see in my ULS logs that a server could not be reached by HTTP Ping. My question is this: Do the APP servers need IIS running a website on port 80 and configured to respond to HTTP Ping?

Hi,

You could turn off the firewall in the app server to check if it can work.

And you also could check if the SharePoint ports in app server are occupied.

More reference:

The article below is about how to enable Ping in Windows Server 2012.

SharePoint Servers that are not hosting Web Applications do not need to be listening on TCP/80 or TCP/443 (or, if you don't have a Web Application that listens on tcp/80 and/or tcp/443, again you do not need those specific ports). That said, all SharePoint Servers in a farm must have IIS installed, and they will deploy, at the very least, the SharePoint Web Services IIS Site, which is used for web services calls, but does not listen on tcp/80 or /443.

HTTP Ping refers to keeping the IIS Application Pool alive. If the pool does not respond to the ping, it is considered failed.
