In a new Windows 2012 R2 setup, we are seeing an issue where we cannot bind to the 10Gb card that is installed. The server is a DL380 gen 8. The onboard HP 1Gb NICs can successfully be bound to the ISCSI target service when configured. The Intel(R) Ethernet Server Adapter X520-2 adapter does not. Instead, we see the following error:
The Microsoft iSCSI Target Server service could not bind to network address X.X.X.X, port 3260. The operation failed with error code 10049. Ensure that no other application is using this port.
The workaround in https://social.technet.microsoft.com/Forums/en-US/4431ba80-fc2a-49b1-99a6-1f3811c0aec3/my-windows-2012-iscsi-target-service-needs-to-be-restarted-every-time-the-server-starts?forum=winserver8gen is in place, but that does not correct the issue with the X520-2 adapter. Latest drivers from intel have been installed for the X520-2.
Thoughts?
