Active Directory Upgrades: Additional Features

Upgrading your domain and forest functional levels is a simple task once the new domain controllers are in place and the old ones are decommissioned.  But what about the features that take advantage of the upgraded functional levels?  There are two important things to do as a domain is upgraded to the 2008 and 2008 R2 functional levels: migrate SYSVOL to DFS replication and enable the AD Recycle Bin.

Although these features have been available for a long time, it’s good to revisit items like these occasionally.  Although many domains are using them, there are plenty of environments that have yet to take advantage.

Testing File Server Performance

Measuring file server performance can be a little tricky.  In this post, we are going to look at each of the components that affect the speed clients can read/write to a file server.  After gathering baseline stats, we'll look at 2 different ways to test the performance of a file server: using the Windows Explorer file copy UI and using the diskspd command line tool.  We'll find that the speed shown in the Windows Explorer file copy interface isn't a reliable measurement of the disk throughput on the backend.
