    This service has started to use serious processor time on my machine… 40-50%. Not sure if one of the dependencies are causing the drain, but as you said there are numerous services that depend on it so it can’t be disabled.

    I had the same problem as dre and I solve it by uninstalling the new SonyEricsson PC Suite that appeared for Vista. I also unpaired my mobile from my PC in Bluetooth connections.

    I disabled the Toshiba Bluetooth suite and the problem went away. I think we have it narrowed down to a Bluetooth problem. There are numerous forums on the issues with Bluetooth and Vista, hopefully Microsoft is working on some fixes. To their credit, they finally pushed out a Bluetooth Stereo Audio driver so now I can use my wireless headphones with Vista. Better late than never I suppose.

    What has brought me here and got me wondering enough to comment is the ‘cpu: n/a’. I ended a srvchost process cause my cpu was being maxxed out for no apparent reason and when I ended that srvchost process my computer needed to reboot which was a pain in my ars as I had data transfering that I did not want interupted or compromised by outrageous cpu useage.

    If anyone can help me I would greatly appreciate it, I have a new Dell demension c521 with windows vista , and it is constantly freezing up It usually says web page not responding or something like that , but I’m now getting the message “windows must now restart DCOM server process launcher services terminated unexpectidly. I have no bluetooth programs on my pc ,wondering if this could be a problem with hard drive or is this something I can fix myself? Please help ! a new computer shouldn’t run this slow !!

    Sheila,

    I’ve never owned a Dell myself or ever would put myself through that sort of experience. My first thought was your problem is related to the fact that it’s a Dell system. However I base these comments on my experience with my last employer when they decided to upgrade to Windows based systems and chose Dell as there vendor. I can’t say I have any certain knowledge of the issue as you’ve described. None the less when my previous employer purchased multiple Dell systems for there upgrade it was my responsibility to set them up with our business software via our local office network also to include web access. Throught out this experience it was found that one system had been shipped to us with a defective hard drive. To this end I also found that Dell phone tech. support rep’s are next to useless with there limited range of technical knowledge. However the Dell protocol is that even if you have the onsite srvc term in your warranty the phone rep’s still have you jump through numerous hoops in what they call a sort of diagnostics which is far from that. What I suggest is make however many numerous calls to phone tech support and follow the skew of misc. instructions as well as dealing with the frustration involved in finding the person on the phone is no use in assiting you with any tech. issue. Through the course of this most likely they the first conclusion they will come to is ‘oh it must be deffective hard drive’. Now understand I offer these suggestions hoping you have the onsite support srvc still available in your warranty terms as that will be the final measure. There first suggestion however will be for you to send the hard drive for them to test and so on. Please do not accept this as an option as opening your tower voids warranty and service agreements provided to you with your purchase. Tell them this and that they need to honor the onsite service. When this is honored I believe it will be about two days later or so a tech will show replace the hard drive. That is my best advice unless you find someone to respond here with an abundant knowledge of this process thats causing your problems with a known resolution to solve your issue. Good Luck.

    You’ll need it dealing with those phone tech pions at Dell..=)

    Sheila, I am having the same problem as you. I have a Dell Inspiron 6400 with Vista. I have not had any issues with Vista until an automatic update of the SP1 was installed; crashed my computer and had to take it in for repairs. Ever since, the computer is showing DCOM Server…. the same message as you? I have looked at forums, doing all the suggested ideas and nothing. Has anyone found a true fix?

  • slavebrain

    Oct 28, 2008 at 4:41 pm

    i think kalin may have hit the nail on head. EVERY single vista update brings with it anomalies and incidents far worse than anything they profess to cure.

    not much of an answer, but roll back to the original and disable updates.

    works for me

  • Kalin

    Oct 29, 2008 at 12:31 pm

    I will have to agree with slavebrain, the best thing you can do is either do not install any new updates, or attempt to install updates, see how the system takes it and if it crashes, you will have to do a system restore. You may be lucky if you restart the computer a couple of times. It worked for me once in a blue moon. Another fix; is if you can figure out what program is affecting the server, disable automatic start, or at least delay the start. The problem for me was that at start up, Registry Mechanic was booting the same time the system was, causing errors and for the server to stop working. I went and delayed the start for the program and it solved the server problem but I still have a similar problem of vista desktop screen locking (freezing) after new updates with no error messages.

    Sheila has no idea what she’s taking about. If you are going to give someone help. please don’t berate them that they made a bad choice. I have companies running on Dell servers and they are better than most of the optios out there. I don;t work for Dell or do I support them in any way.
    The problem he is having is related to Vista. It is a kno issue and they are working on it.

    Out of the blue my HP Compaq laptop will not get past the point where it says welcome, and vista starts loading, I am getting – “DCOM server process launcher services terminated unexpectidly” and sometimes “plug and play terminated unexpectidly” it is stuck in a constant loop of restarting itself and i cant seem to fix it.. any ideas at all??

    This DCOM Server Process Launcher is controlling Task Scheduler…you can not enable ….does anyone have any ideas to bypass to allow task scheduler to function independantly

    I am using Lenovo. No malware, etc no issues with the file system. I have got no idea what to do.

    Hi everyone, I had the same issue with my laptop (Dell XPS 1330) with Visat SP2. I had my DCOM-server taking my 45-50% CPU usage constantly. This was not doing any good to my battery usage either and the laptop was running hot all the time. There are two things that worked for me.

    1. Sigmatel has the sound driver for my laptop. I switched off the sound enhancements by right clicking the speaker on the taskbar and selecting playback devices, then select the speakers and click on properties. THen go to the enhancements tab and check disable all enhancements.

    2. As discussed earlier, the bluetooth does have its share of problems. I have a wireless headset and Windows mobile phone that are added. When I switch off the bluetooth device, that seems to get the CPU usage down by keeping SVCHost/DCOMserver from acting up.

    I seem to have had luck with my machine for the time being. I hope this helps. Cheers!

    I have the same problem with DCOM service taking up way to much of my cpu (40-50%). And that started when I installed SP1 for vista. I think I will try to roll back before SP1 just because it is another microsoft bs process. LOL
    Hate it when microsoft makes me run whatever they say and can’t use “PC” without the program(s).
    Sorry, if that offends anyone, but I hate Microsoft!!! And before the Bill Gates lovers chime in….. Yes I know I don’t have to use windows, but what can a person really do when most every program out there is designed for windows :(

    I had the same problem, my DCOM service was consuming so much CPU like 50%, i figured out, that it was because of python… I don’t know why, but when i started to uninstall it, the DCOM process went to normal condition.

  • Krammuel

    Oct 29, 2009 at 5:07 pm

    OK!! Update..
    I found that it was actually SP2 that installs the DCOM process :(
    What I decided to do is install vista twice on my PC. The 1st install is the original with all updates and has all my main info on. The 2nd windows boot is only updated to sp1 (which came on the windows disk), and I select the updates to install. I basically kept it as bare as possible. Putting only my gaming and other programs that need most or all of the cpu to run.
    Conclusion: This has been (for me) the best solution to the problem. Computer runs like a champ now.

    Now, I wonder with Win7 if it will be possible to have this, a smooth running computer? I say that because the DCOM will be in the core of the system and can not be removed or kept from being installed. The claims from MS that Win7 will run better then Vista is, ummm, not completely true. I say this because they are making it easier for the idiots to use their PC. But, that is where the flaw is. It takes windows to much processor time (and RAM) to make it work that way.
    Anyways, it’s my opinion.
    Hope the 1st part of this helps resolve issues with Vista.

    Windows 7

    so far, and let’s not be too hasty, a marvel. i’ve been running it for about 3 months now without major incident. can’t personally see why anyone would leave user account control on, but then i can’t see why anyone would trust microsoft security either.

    does address the poor memory management inherent in windows as i hoped, but as long as you’ve enough ram, it seems to work well.

    i can’t comment on upgrade tho: both cleam installs.

    can’t comment on the fancy features either: just want a stable, fast, working system: this it appears to deliver

    hope it helps

    And XP has DCOM in it too….
    A friend has XP and has been having some issues and I think it is installed with sp2 or sp3 (not positive which sp). Also, since XP doesn’t really support bluetooth and most people with XP (could be wrong) don’t upgrade the media player. They don’t really run into this problem as much. But, is something to consider if you are having problem with XP

    Thank You Slavebrain

    You are the 1st person to comment on Win7 and not get into your personal feelings (ie: its crap, its better then anything else, and so on….).
    Just tell your personal experiences honestly! That’s refreshing, since most either bash MS or kiss their asses!!!

    1. Dell still owns you computer even though you may have had bought it outright. It is embedded with Dell in the DCOM you want to eliminate.

    2. Dell like microsoft own you through your computer program. dcom active and next to impossible to extract from necessary services.

    3. extracting services you need like color management, ect. you choose, requires a programmers menu/chart/”properties” to see where each locked in prograsm u want is at so that you can at least siable most of DCOM.

    4. Try to disable “OLE” first.

    5. I have dedicated more than 50 hours to removing dcom and its nasty Remote Control (masking under the guise you gotta have it if you game). I’ve gotten no help from microsoft anf mind you they didn’t paya cash for my laptop I did.

    Anyone interested in a class action lawsuit?
