Identify TCP dynamic port of SQL instance

Summary

SQL ports are a key information of your Lync infrastructure, they need to be clearly identify in order to guaranty a proper replication.

The objective of this article is to determine the TCP port use by an SQL instance. By default SQL Server listens on TCP port number 1433, and for named instances TCP port is dynamically configured.

Update Microsoft certificate authorities to use the SHA-2 hashing algorithm

Recommendation: Microsoft recommends that certificate authorities no longer sign newly generated certificates using the SHA-1 hashing algorithm and begin migrating to SHA-2. Microsoft also recommends that customers replace their SHA-1 certificates with SHA-2 certificates at the earliest opportunity.
