    W2K3 Server can access W8 W8 computer cant see W2K server


    Hi there
    Why does Windows Networking always seem to hose things up ( Linux works EVERY time)

    I have two computers on the SAME test private LAN one Whitehorse (W2003 server) and the other Blackdog (W8 Enterprise) both enabled "Shareable and Visible".

    View from W2003 -- can see and access disks C,D, and F on W8 Computer

    View from W8 - Networking shows the computer Whitehorse (W2003 server) but can't access any disks etc (or even its printer). PING even fails but W8 obviously knows it's on the Network because its found it. The stupid Windows diagnostics when you click Diagnose doesn't help at all --in fact I've NEVER found the network diagnostic panel of the slightest bit of help ever.

    I've switched off firewalls etc while testing so there's no security rubbish to take care of while I'm trying to get this to work. LAN is purely LOCAL -- no computer is on "the other side" of a router.

    Both machines can access independently the Internet through a Local router and connections are via LAN cable so nothing should be simpler. !! But can I get this to work !!.

    I had a similar problem with W7 but it seemed to "Disappear" without me actually doing anything -- the proverbial "Ghost in the Machine" I expect.

    Screenshots enc.

    (Windows Networking Grrrhhhhhh! -- I'm not particularly technical with this stuff but any time I've used Networking with Linux it works STRAIGHT OUT OF THE BOX and there's no problem sharing from or to windows. !!)


    Note -- Other W7 / Linux / XP computers connected to this SAME LAN (currently switched off) have NO problem accessing the server -- It's just this W8 Machine (W8 x-64 Enterprise version).


    Thanks

    Jimbo

    Assuming this Windows 8 Enterprise machine isn't locked down with Group Policy.

    This type of problem usually requires that you change the lanman server parameters in order to get Windows 8 working with older servers. Do these adjustments on the Windows 8 machines that needs to connect to the server.

    Control Panel - Administrative Tools - Local Security Policy

    Local Policies - Security Options

    Network security: LAN Manager authentication level
    Set to Send LM & NTLM responses only

    Set the Minimum session security for NTLM SSP
    Disable Require 128-bit encryption

    Reboot all machines after making the adjustment.

    There are two separate settings for disabling the 128 bit encryption.

    Hi there

    Thanks

    Solved -- added an XP machine as well --Its fine
    now. Your trick solved the issue -- tested with an XP machine -- server down for updates at the moment -- but it's fine

    All 3 machines on the lan can see each others disks etc . (W8/W7/XP combo)

    scrshot enc.

    Rep +1 for the solution --thanks -- I spent nearly 3 hrs one way or another messing around with this --wouldn't have found that solution in a million years.

    I'm usually OK at "getting round" a problem -- but Networking is something else --now I see what these guys are paid for.

    Cheers

    Good deal Jimbo.

    Yes this little problem has been around awhile. Of course if Msoft didn't add the extra security then people would complain that there are security leaks so no way to win for them.

    I've seen those same settings fix quite a few Win 7 machines that also couldn't get into those older servers so this fix is universal and has been around quite awhile. TechNet has some threads about this.

    Next time this problem occurs you will know right where to go.

    I knew the answer after reading the second sentence in your post so all I had to do was copy paste from another old post that I had in favorites.

    I'm afraid I don't know if it will solve the issue, but I did find a setting about 128 bit encryption in regular Control Panel.

    In Control Panel, go to "Network and Sharing Centre", then "Change Advanced Sharing Settings".

    On that Advanced Sharing screen, there are 3 collapsible sections for "Private", "Guest or Public" and "All Networks".

    Within All Networks there is an option to turn off 128 bit encryption.

    Found a Solution...Credits for jobaba in another Windows Forum

    "you can fixed this yourself for now by forcing windows to make the network drives available to standart and administrator acounts:
    1 - run regedit
    2. - locate HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Policies/System
    3 - create a new DWORD entry with the name EnableLinkedConnections and value 1.
    4 - restart your computer
    5 - now you can see and use network drives with these installers or applications."

    This automatically mapped all my routers (3) and their drives

    I'm still not sure what Jose was trying to do here.

    Do these registry settings allow you to connect to a Domain with Windows 8 Home version?

    I've already faced similar problems. Very useful information !
