APPLIES TO


 * Microsoft Message Queuing 2.0

SYMPTOMS
Microsoft Message Queuing (also known as MSMQ) messages may not be sent if both of the following conditions are true:
 * The send permissions for the Everyone group on a public queue have been removed.
 * The user who sends the messages belongs to too many groups.

Note The number of the groups may vary.



CAUSE
This problem occurs because a buffer that was passed in a call to NetUserGetGroups was too small for users in many groups.
