DCOM Error 10016

Discussion in 'Server Networking' started by L HeimendingerLM, Oct 17, 2006.

  1. The description of this error in the system log is:

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

    The help reads as follows:

    1. Using Regedit, navigate to the following registry value
    HKCR\Clsid\clsid value\localserver32
    The clsid value is the information displayed in the message.
    2. In the right pane, double-click Default. The Edit String dialog box is
    displayed. Leave this dialog box open.
    3. Click Start, and then click Control Panel.
    Double-click Administrative Tools, and then double-click Component Services.
    4. In the Component Services snap-in, expand Computers, expand My Computer,
    and double-click DCOM Config.
    5. In the right pane, locate the program by using its friendly name.
    Right-click the program name, and then select Properties.
    6. On the Security tab, in the Launch and Activation Permissions group box,
    select Customize, and then click Edit.
    Add the user to the permissions list, and give the user the appropriate

    But here is what i find in the registry as sub-keys for this value:
    (default ) Network Connection Manager Class
    AppID {27AF75ED-20D9-11D1-B1CE-00805FC1270E}

    there is no localserver32 key.

    If I ignore that silly aspect and try and find Network Connection Manger
    Class, I cannot. Even more baffleing to me is how to add NT
    AUTHORITY\NETWORK SERVICE as a user if I try to customize permissions on any
    DCOM class.

    This is a Windows 2003 server running ISA 2004. It has two NIC cards in it,
    one with a address for the inside network and the other with a
    public address in Internet space. As far as I can tell , all the ISA
    functions are doing just fine. It links to another remote domain, supports
    the published servers, etc.

    However, the internal clients are really suffering from network pauses.
    Every minute or so, clients lose connection to Exchange server, then it
    recovers. Launching web browsers will sometimes take a minute or so to
    initialize. Occassionaly - every so often all day long - machines will
    freeze for between 5 and 30 seconds.

    There are no other errors being logged on any other servers or clients, only
    on the ISA machine. During these "blackout" intervals, there seems to be no
    or very little network traffic. There is no conclusive proof one way or the
    other that the timing of blackouts or slowdowns is the same for all clients
    or is independent of one another.

    Search after search using all sorts of keywords has turned up nothing of
    substance. Any help would be much appreciated, including is this an ISA or a
    Windows problem.

    Thanks in advance.

    Hi LarryH,
    I have this exact event being logged every 10 mins or so but have to say we are not suffering any network issues so i think this may be a red herring to your "blackout" problem. Much more likely is the correct gateway, DNS and general network config. The server giving me this error does not have ISA or exchange, just AD with WSS installed.
    Hope this helps to focus on the problem?

  3. Thanks, Andy.

    Interestingly, my network delay problems disappeared as magically as they

  4. Hey, it's Windows! I went through all the same hoops, removing and
    re-installing components. The fix described just took a minute or so and has
