Okay, all remaining software reinstalled without any additional issue.  To close this out let's recap this incident in case some other person encounters the same issue as me (TLDR see step 8). 1) I wanted to use DPM (Dell Power Manager) because my computer's fans were going crazy and I couldn't control them. 2) Unfortunately, I got an error 1720 any time I did anything with DPM.  There are countless articles on the internet and I'm fairly confident i tried them all (at least the first 4 pages on google search), without success.   3) I decided to reach out to Dell.  For good measure I updated all my firmware prior to attempt to use so I was up to date.  I was also up to date on Windows updates because I was convinced this was a software or firmware issue (suddenly) causing my fans to go awry because the computer rarely moves from the same position on my desk. Upon my initial query to Dell on this topic they chose to send a hardware tech out to replace the fans, motherboard, thermal paste and processors.  While he did a good job, he had no software experience and the problem persisted through all of this.  4) I redoubled my efforts at researching possible causes and decided to create this post.  Everything seems to point to a problem with COM+ and the Microsoft Distributed Transaction Coordinator (MSDTC) having a communication problem.   5) Dell private messaged me and said "something is corrupt, reinstall Windows" even after I pleaded for a more surgical option instead of the Dell Tech Support Standard Sledgehammer Solution (TM).  Much to my annoyance, I performed the OS reinstall.  The problem did go away upon reinstall, but as I was installing my applications, the problem returned.  Unfortunately I did not know which app was to blame as I didn't track it so.... 6) I initiated a system restore point back to just after the reinstall of Windows and started again, this time testing the COM+/MSDTC after every action I did and creating restore points after every step.   7) The problem manifested itself after I installed (from the Microsoft Store) the "HP Smart" app for my HP Officejet 9010 Multifunction Printer/Scanner/Copier.  Armed with this specific information, I found an article eluding to HP software having a very similar problem and same error message on an HP Laptop which indicated there was an HP service that they disabled to make this problem go away.  I found the "HP Print Scan Doctor Service" and disabled it.  The COM+/MSDTC communication issue immediately went away. I am now able to use the full functionality of DPM to help control my fans, and wouldn't you know it, the fan speed is low and the temperature of the CPU is averaging around 45°C which is WAY better than the fans running at full blast constantly and running at 100°C.  Amazing how software can cause thermal issues like this! I just wish I hadn't needed to reinstall Windows to get to the bottom of this.  I hope this helps someone out in the future! [IMAGE]  
Hi,  I have been having issues with my Dell XPS 9570 running its fans near constantly. Running HWInfo showed that the CPU was getting to 100°C. I added an external fan tray which is helping, but the problem is that this was never an issue.  A Dell tech came out and replaced the motherboard, thermal paste, processor, and fans without any noticeable difference.    I read that there are more options to better control the fans and such in the DPM (Dell Power Manager), but when I go there to update it, I get error 1720 repeatedly.   [IMAGE] I've followed just about every link from Microsoft and others that I could find online performing their suggestions but have had no success. When I dig into it, it indicates a problem with communicating with the Distributed Transaction Coordinator (see screenshot below of Component Services) [IMAGE] The event viewer has a bunch of errors related to the DPM update and all say "The Transaction Manager is not available. (Exception from HRESULT: 0x8004D01B)" [IMAGE] I did see somewhere that my .NET might be the incorrect version, but I'm running the latest Windows 10 release and my .NET version is and it is 4.8.04084: [IMAGE] The Microsoft Store says I need .NET 4.6.1, but I am unable to install that because it is already newer. [IMAGE] Here was an attempt at installing .NET 4.6.1 just to try: [IMAGE] So, anyone got any ideas on how I can solve this problem? I haven't encountered it for any other applications and the computer is running fine otherwise. Also, yes, I did disable Antivirus and Firewall etc which didn't make any difference.   Your help is appreciated!
DPM update error 1720, CPU 100°C, solved
