Working on the FW ports for the project, and noted that Microsoft confuses IT guy again – DFSR port
In reference 1, Microsoft mentioned that TCP 5722 is for “RPC, DFSR (SYSVOL)” and this article is applied up to W2K12 R2 (dated on Mar 28 2014)
But the fact is: TCP 5722 is fixed for DFSR in W2K8 only. In Windows 2012, DFSR is back to dynamic port as the same W2K3.
If you want to fix the port in W2K12, yes, possbile but have to install the File Services Tools feature with the Distributed File System Tools option and enjoy dfsrdiag command
