Event InformationAccording to Microsoft :
Cause :
A user who is logged on tried to create another logon session with a different user's credentials. Typically, this occurs when the user runs the RUNAS command and specifies a different set of credentials.
1)The Logged on user fields specify the user's original credentials.
2)The Target User fields specify the credentials that the user supplied for the new logon session.
3)The Caller Process ID field specifies the process that made the logon request with the new credentials.
4)The Source Network Address and Source Port fields specify the source IP address and source port number for the remote computer that sent the logon request, if applicable.
Resolution :
No user action is required.


Cause :
The outbound network request was initiated with non-default credentials. Normally, outbound network connections use the credentials of the logged-on user, or of the service or machine account. However, in certain cases, such as when using the RUNAS command with the /NETONLY option, explicit credentials can be specified. This message is displayed for informational purposes only.
