Event ID 2177 The Message Queuing service rejects incoming messages when it is unable to check whether the sender is allowed access to the queue for sending messages. In this case, the queue affected is %1, but note that an event might not be issued every time this problem occurs.
V-437-2177
MSMQ Service does not have access to the group memberships of the sending user.
The recommended solution is a two-way trust to allow MSMQ to enumerate the group permissions in the user domain. A potential workaround is to allow Everyone and Anonymous Logon access to all Enterprise Vault MSMQ's. Be aware and review the security implications of this in your environment before proceeding with this option.
