DCOM Error

[Macanta]

My Windows XP Home Edition has developed a fault lately manifesting itself
with a slow bootup process, slow start up process and often slow system
responses when the OS has eventually loaded. I've copied the following error
messages that are displayed in Component Services which I accidentally
stumbled across while trying to find out what the problem was.


DCOM got error "%1058" attempting to start the service upnphost with
arguments "" in order to run the server: {204810B9-73B2-11D4-B
F42-00B0D0118B56}

The Application Management service terminated with the following error: The
specified module could not be found.

Any ideas or suggestions gratefully received.

Many thanks.

Hi Macanta,

See if stopping and disabling the "Universal Plug and Play Device Host"
Service helps. Click Start/Run and type Services.msc to configure Services.
For the 2nd error message, it looks like the file appmgmts.dll is missing in
the following folder:

%SystemRoot%\System32

If the DLL is missing, see if extracting a new copy from the source helps.

Thanks Ramesh - I found that the appmgmts.dll file was missing as you said
and I have replaced it. The "Universal Plug and Play Device Host" was
already disabled though. Despite restoring the missing file there has been
no improvement - I have no faith in the system as it operates at the moment
so I'm going to back up all my data and format the drive and do a clean
reinstall of XP. I can't have it fail on me when I need it.

Cheers.

Macanta,

Another checkpoint is to make sure that you've extracted the latest version
of the appmgmts.dll file. (if you have a Service Pack installed). Using an
older version of the DLL (shipped with base XP CD) in a SP2 level system
_may_ cause a problem, though I've not compared the module versions.
