Quick post for a Friday!
A customer had an “interesting” issue where the DAG networks were not being displayed inside the Exchange Management Console.

Other times the display would look corrupted and the navigation tree would not be properly rendered.

In a previous post we saw the Microsoft requirements for the exclusions that must be added to file system AV on Exchange servers.

Every so often I see folks run into issues with scripts/one-liners that they obtained from a blog or crafted themselves. One common issue is when they think the command is perfect and then when they go to dump the output to a file, the content is mince. **
