NT Authority error

[gonzangus]

Hi, the case is that i have a lot of this errors in the Application Log:

The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID
{BA126AD1-2166-11D1-B1D0-00805FC1270E}
to the user NT AUTHORITY\NETWORK SERVICE SID (S-1-5-20). This security permission can be modified using the Component Services administrative tool.

Actually I found some things that should fix this error, but before I want to know wy this error raise in first time. If anyone could tell me that I will be very happy :)

This Technet article describes the DCOM Security Enhancements in Microsoft Windows Server 2003 Service Pack 1:

{BA126AD1-2166-11D1-B1D0-00805FC1270E} CLSID is "Network Connection Manager Class".

This is the solution, it worked for me:
1. Click Start | Run and run dcomcnfg.exe

2. In MMC, open Component Services | My Computer

3. Right-click My Computer, choose Properties, select the COM Security tab. Click on the edit default button in Launch permissions options area

4. Add network service and give it appropriate perms (Local Launch and Local Activation permissions)

If that doesn't do the trick:

1. Start DCOMCNFG

2. Under Component Services -> My Computer -> Dcom Config -> Netman click
Properties, then Security tab

3. In Launch and Activation Permissions box click Edit.


4. Add Network Service with Local Launch and Local Activation permissions
