Question

Suspicious event log entry

Asked by: shellit

Hiya all, ive noticed a lot of recurring event log entries in the Security log in our Windows 2003 server.

Can anyone explain exactly what this may be? It displays anonymous login and so i need to make sure nothings happening in the background. Heres a dump of the event log message:

Event Type:      Error
Event Source:      DCOM
Event Category:      None
Event ID:      10016
Date:            21/09/2007
Time:            11:15:52
User:            NT AUTHORITY\ANONYMOUS LOGON
Computer:      UKLPGCOM01
Description:
The application-specific permission settings do not grant Remote Activation permission for the COM Server application with CLSID
{5A5AA0AA-1DEB-4683-96B0-B43301E83971}
 to the user NT AUTHORITY\ANONYMOUS LOGON SID (S-1-5-7).  This security permission can be modified using the Component Services administrative tool.

Check the registry entry for CLSID 5A5AA0AA-1DEB-4683-96B0-B43301E83971 and paste the information back here. Is your RDP service on?

Ahh right i see, it seems to be pointing to a HP Port, this is a copy from the reg key, it seems harmless enough although can i turn this off inthe event log as theres so many error messages relating to this its hard to view anything else!
