Event ID 104 — Windows NT Token-Based Application Malformed Requests
Applies To: Windows Server 2008 R2
Web Agent for Windows NT Token-Based Applications Malformed Requests logs token requests, session cookies, and sign-in requests that are associated with the Windows token-based agent. Malformed Requests also provides information about protocol requests that are made to the AD FS Web Agent and client cookies, and it records any sign-on issues.
|Product:||Windows Operating System|
|Message:||The AD FS Web Agent for Windows NT token-based applications encountered a serious error. The cookies that were presented by the client could not be validated.
This condition occurs when a client presents well-formed cookies that are not valid. If the client is known to be a valid user, this error might be caused by a transient issue. For instance, trust properties (for example, certificates) may have changed recently or revocation status may not be available from the certification authority.
