By default, connections from Outlook to Exchange 2013 are authenticated with NTLM. However, in environments with several CAS servers and many clients, NTLM generates unnecessary load on the DCs, precisely because load balancers no longer have to worry about persistence. It is better to use Kerberos authentication here so that not every CAS server has to re-authenticate the connection ... Read more

I was looking for a good and simple SPAM filter that also works with Exchange 2013. Of course, I prefer products that require little effort to get them up and running. Precisely because anti-SPAM can be a sensitive issue, I wanted a solution that was easy to administer and ... Read more
I wish you all a Merry Christmas and a Happy New Year. And don't forget to drop by again in the new year. Frank PS: I will use the time between the holidays for a few revisions of the pages, so don't be surprised if FrankysWeb is offline from time to time
Exchange 2013 has the Managed Availability functions. Among other things, Managed Availability is able to put Exchange services into maintenance mode. This is important, for example, when updates or service packs are installed on Exchange 2013 servers. During the installation of CU3, however, it happened to me that the maintenance mode was not terminated again. Read more
Unfortunately, the standard license overview of Exchange 2010 does not provide much information. You cannot see what Enterprise licenses are required for, so if you have activated an Enterprise feature by mistake, you will have to search for a long time before you can deactivate it again. In the Technet, however, there is a script that breaks down the licenses in more detail. This means that you can ... Read more

Here is another small script from the "Quick & Dirty" series. The script can restart a server and sends a mail with the status: #Server restart $servername = "SERVER01" $to = "frank@frankysweb.de" $from = "rebooter@frankysweb.de" $smtpserver = "smtp.frankysweb.local" Send-MailMessage -To $to -From $from -SmtpServer $smtpserver -Subject "Restart for server $servername" -body "The server $servername ...

Forefront TMG has now been discontinued and a replacement will have to be found sooner or later. There are now several manufacturers who are filling the gap left by Forefront TMG. I will test some promising solutions and publish a howto for each of them. Finally, there will be an article comparing the solutions with each other. Read more
Unfortunately, the IIS web server does not offer the option of automatically deleting older log files. Either you write log files to disk continuously, or only one with a selectable size. I have therefore created a small script which deletes the log files after a selectable period of time. The script is available for download: Using a scheduled task, the script can be ... Read more
