Microsoft's December 2025 update KB5071546 changed NTFS permissions on C:\Windows\System32\MSMQ\storage, causing MSMQ queues to become inactive and generate “Insufficient resources to perform operation” errors that can crash IIS-hosted sites under load, particularly in clustered enterprise environments; Microsoft acknowledges the issue and recommends contacting support for a targeted workaround while no public patch has yet been released.
