    I got this DCOM error in system event log.

    Event Type: Error
    Event Source: DCOM
    Event Category: None
    Event ID: 10003
    Date: 9/3/2004
    Time: 10:29:21 AM
    User: N/A
    Computer: RASSERVER
    Access denied attempting to launch a DCOM Server using
    DefaultLaunchPermssion. The server is:
    The user is Unavailable/Unavailable, SID=Unavailable.

    There's also numerous failed attempts login in from this machine. IS there
    anyway to detect where this attack came from?
    Thanks a million!

  2. With a software or hardware firewall to log the IP address. www.sygate.com,
    www.kerio.com, www.zonealarm.com are free. Or if you're using Windows 2003
    Server, you might be able to use the included firewall.
