I have a iscsi connection made in the Iscsi Initiation in Windows 2008 R2 that connects to a LUN of a Synology device.

In these LUN i have sql databases.

My problem is that all morning the ISCSI connection is disconnected in these particular server.

I have another server with the same configuations but connected to a differet LUN and it is working fine without problems.

I tried everything that I can find in the internet but the issue continues...

Regards
Joel

OK. Please check the Application but mostly the System Logs.
Check for any Warnings and/or Errors in these two Logs. Are there any during the night?

the only error that I have in the event viewer is the sql server error because of the missing drive with the dbs

Is this a physical server or virtual? Does it use a specific card for iSCSI or does it share the NIC?

Please consider updating the NIC driver to version "4.7.29.1101 (18 Feb 2014)".
You can download the driver from this link. Let me know how it runs.

I think you didn't even try because the link points to the 64bit driver. I gave you a suggestion: it is up to you to consider it or not.
So your reply to my suggestion might be:
a. I will consider updating, or
b. I refuse to consider updating.

The reply you gave me, AFAIK, isn't applicable because the driver is 64bit.
Please reply. Thank you.
