    Thanks for your help.

    I noticed that it was using a random port each time. I've also installed TCPDump on the SAN and gave it a try.

    Not really sure how to use it properly. I ran it and verbose it to a log file. Just trying to figure out what it means now.

    Finally, I've gotten a hold of some information using netstat and I believe the culprit is "microsoft-ds" (directory services for smb).

    I'm not 100% sure that is the cause of the heavy process load on the smb, but there are only 2 connections from the windows 7 box, it and the telnet session.

    Anyone else having issues with the microsoft-ds service?

    No it wouldn't be Directory Services unless an active connection was trying to be made to or from the Windows client. A means of parsing TCPDUMP is to only capture packets with a source IP of the Windows machine.

    SOLVED!


    DOH!

    I was wrong. It turns out I accidentally disabled the 'Client for Microsoft Networks' option in the LAN settings. This in turn disables the microsoft-ds service so it stopped pinging the SMB.

    At least now i know it is an issue with how Windows 7 is accessing the SMB share.

    Is there any way to disable the default way windows 7 accesses SMB and use third party tools to access the smb share?

    Thanks Logic,

    Gave the manual regedit a try and that didn't work, however that gave me an idea.

    I removed the network printer (printer is attached to the smb device which is then shared so i can print from any computer) and that seems to have fixed the issue.

    So, I guess the question is, what is the printer share on windows 7 trying to do. Immediately after I add the printer, I notice my network usage spike and the SMB server lock up.

    Anyone having network printer sharing problems?
