Turn off windows zone security feature “unblock application”

  2. In the Search box, Run box or console window type: GPEDIT.MSC to bring up the Group Policy Object editor.
  3. Navigate to User Configuration > Administrative Templates > Windows Components > Attachment Manager. Here you will find a couple of policies related to this feature, but to disable it you’ll want to ENABLE the policy called “Do not preserve zone information in file attachments”.

MSMQ Message Queuing Problems

The results of a recent MSMQ evaluation. Lets assume for use in an enterprise, where there will be a dedicated remote MSMQ cluster configured for high availability and reliability.

  • Microsoft clustering is the only option, requiring Windows Server Enterprise licensing
  • Microsoft clustering requires a shared SAN( or  iSCSI at a performance cost)
  • Public queues require Active Directory, and are listed in the AD catalog
  • Message routing is only supported with public queues
  • MSMQ must be installed on ALL clients sending messages
  • Clients can’t push directly to a remote queue – messages are queued locally
  • Once the journal is full, no more messages can be written to it
  • Messages can not be expired from the journal queue (but they can form regular queues)
  • Messages cannot be received transactionally from a remote queue (MS work-around)
  • Private queues cannot be created remotely
  • Remote private queues cant be enumerated
  • Performance counters are only available for queues that have active sessions (active queues)
  • There is no concept of publisher/subscriber
  • Message delivery expiry is global to a transaction (makes custom journaling tough)
  • Cannot backup an individual queue (but can backup and restore the entire MSMQ)
  • Cannot backup public queues
