WEBDAV Error on mapped drives - locked files RRS feed

  • Question

  • We are getting a strange error when using mapped drives only on certain computers and certain configurations:

    Windows 7 x64
    Office 2010 w/ latest updates
    Trend Micro 

    When trying to access a locked document over mapped drives it gives an error saying "X:\path to file\ cannot open file"

    It is a very generic error so I ran a capture on the packets here is the error I believe is what is causing it.

    Now hop onto my computer and we get

    Note CoreServiceShell is Trend Micro it was disabled on the remote PC to try diagnosis. It opens fine on my PC as the other one never tries NTLM Auth to the file. If the remote PC opens the file in the WEB front end it will work, it is JUST mapped drives

    Any thoughts or ideas are really appreciated
