DCOM Error - Event ID: 10015 - Source: DCOM

Last Updated: 5/21/09

This error has to do with HP printers and the DCOM component "HP Port Resolver". I was getting this error on a Windows 2003 print server. A sample of this event error is included below:
Event Type:	Error
Event Source:	DCOM
Event Category:	None
Event ID:	10015
Date:		10/27/2008
Time:		11:53:00 AM
User:		(username here)
Computer:	(server name)
The machine wide limit settings do not grant 
Remote Launch permission for the COM Server application
 with CLSID {5A5AA0AA-1DEB-4683-96B0-B43301E83971}
 to the user (username) SID (user-sid).  
This security permission can be modified using the 
Component Services administrative tool.

I believe that the "HP Port Resolver" is unnecessary. I fixed this problem by running this command from a command prompt:

regsvr32 /u C:\Windows\System32\HpBpro.dll

Then remove the key HKEY_CLASSES_ROOT\CLSID\{5A5AA0AA-1DEB-4683-96B0-B43301E83971}

Basically removing this DCOM component from the system. Remove the "/u" from the command if you want to reverse this process.
