This little powershell script will create the network configuration in Skype For Business, starting from the AD Site and Subnets definitions.
One of the main cause of issues in S4B/Lync implementations is firewall configurations. When you have access to firewall directly or through your direct report, everything is easier but if there is a third party in between, that can introduce problems.
Many times I’ve received “All done as requested” as an answer but after some tests/verifications I found that firewall was still blocking communications.
To help in these type of tests, I’ve modified the default config.xml file of the PortQryUI tool to test/check S4B/Lync and related services.
