Script Deletes Orphaned Printer Ports

The script published in this article was kindly contributed by Bo Riis, a sysadmin working at Danish hosting company dandomain. Here is what he writes about it:

Recently I had some issues with MS Office getting really slow on some of our customers’ terminal servers. After some intensive debugging we came to the conclusion that when users disconnected a session they left behind their open printer ports. It seems like that these ports don’t get cleaned up after a while, like the session they belong to. These ghost ports linger and use more and more resources in the print spooler and Office does not react well to a busy print spooler. One of our servers had more than 3000 of these orphaned ports. [Whoa!]
After searching a little we found one reference to this problem on Brian Madden’s forum. From the scripts there I compiled a script that works on Windows XP and up.
We now have this running on almost 200 TS and the users have given positive feedback on performance gains. Depending on how well or bad behaved they were in logging off in the first place.

Bo runs this script weekly on their terminal servers under the system account. There are two versions which are identical except for the logging capabilities.

Leaked Token Handles Preventing RDS Session ID Reuse

Leaked Token Handles Preventing RDS Session ID Reuse

A recent article on Microsoft’s Ask the Directory Services Team blog piqued my interest. It talks about how leaked access tokens prevent logon sessions to be freed when the user logs off. This wastes system resources that can only be reclaimed by rebooting. A symptom of this happening is that RDS session IDs are not reused.

PowerShell Script: Test Chrome, Firefox & IE Browser Performance

There is more than one way to test the performance of web browsers like Chrome, Firefox, or IE, but regardless of how you do it, you need a consistent workload that makes the browsers comparable. Unless you are testing with synthetic benchmarks (which come with a plethora of problems of their own) you need a way to automate browsers opening tabs and loading URLs. This article presents a simple solution to do just that.

Citrix XenApp 7.6 Logon Slow - Long Black Screen Phase

Citrix XenApp 7.6 Logon Slow - Long Black Screen Phase

Update 2015-04-28: Citrix provides the limited release hotfix ICATS760WX64009 that fixes this issue. More information below. During the research for my session about the XenApp 7.6 logon process, to be presented at Citrix Synergy and BriForum London, I noticed that the logon to my XenApp 7.6 lab server was taking a bit long. Longer, in fact, than the combined durations of the main logon phases user profile loading, group policy processing, logon script execution and shell startup. Much longer. Also much longer than on an otherwise similar XenApp 6.5 machine.

Scripted WordPress to Hugo Migration

Scripted WordPress to Hugo Migration

After having published in WordPress for almost 20 years, it was time for a change. This site is now rendered by Hugo, a static website generator built for Markdown content hosted in a Git repository. The migration from WordPress (HTML) to Hugo (Markdown) was far from trivial. Since I couldn’t find any tool for the job, I developed my own set of migration scripts that fully automate the migration process. You can find them on GitHub along with extensive documentation.

This article shows how to get detailed information about your Mitsubishi heat pump’s status and operations into Home Assistant. Prerequisites You’ll need a Mitsubishi Modbus interface, either the older A1M (serial Modbus/RTU via RS-485 only) or the newer A1M+ (Modbus/TCP via Ethernet in addition to Modbux/RTU). I’m using the Ethernet variant.
