    Angry Can't access a network share, regardless of user - used to be able to. Very weird one

    Hi everyone

    I'm tearing my hair out here with a problem we've been suffering.

    We've recently got a new suite of 30 laptops. I've installed and configured Windows 7 Pro on them all using WDS.

    Everything was fine for a few days...

    Then users started getting errors when logging on because they couldn't access the shared desktop. (\\servername\share$).

    All share permissions and things are fine. Here's the 2 things that make this error really strange:

    1. The user can access the share via IP\sharename. I don't think it's a DNS issue because some of the other shares are available via servername\share. This doesn't last though - soon enough it tells the user they can't access the share from either servername or IP.
    2. Trying to access the same share via \\servername\share$ doesn't work for admins either. Same error message about having access denied.

    This isn't on all of the computers - just a few. But it affects ALL users, regardless of their permission level.

    We've tried everything to sort it, but it appears to be something on the client machine. Because of this, I made a fresh install of Windows, joined it to the domain, installed packages and it was fine. I reluctantly reimaged all 30 laptops. Sure enough, 3 days later we're having the same issues. Also on our 30 netbooks, made with a separate image. Something isn't right here - it's like something is telling the computers not to work anymore.

    Does anyone have any ideas how this can be sorted? I've tried all sorts of things I've found in forums - nothing works apart from a reimage of the computer, then that only works for a few days.

    Thanks in advance

    Have the laptops joined the domain correctly? Does it make a difference wired/wireless?

    Is it possible the permissions haven't been applied correctly?
    Recreate the share and double check share permissions and security permissions. I know you say they are fine ... but 'something' is stopping it working.

    Hi

    Yeah, they're appearing in AD correctly. Doesn't matter whether it's wired or wireless - doesn't work. It's the shares for their documents, desktop and start menu that don't work. The one that does is the shared area.

    If I add a share to same folder (same name but with a 2 on the end) with the same permissions it works correctly. Can't say for how long though.

    Check credential cacheing. Is it possible they're not actually logged on successfully?
    Scratch that. The previous posts wouldn't work if this were the case.
    That'll teach me to try and help without reading the other replies. D'oh!

    Your new 30 laptops haven't pushed you outside of your DHCP scope, have they?
    Could the WAP they're using be damaged/faulty/be connected to a bad wire?

    Checked the scope, They're sitting nicely in our DHCP address range.

    We've got a Ubiquity Unifi system. 24 WAPs. Happens all over school. Also when wired.

    Is the share that does work on the same server as the shares that don't?

    Do you have more than one GPO that controls the shares that don't work? Its possible you have a GPO conflict. Try running the Group Policy Modelling Wizard.

    And here's a seemingly random one but if you've tried everything else then its worth a look: Is the time slipping on the laptops to a point where it is outside the tollerance of the server the share is on?

    We've just got the one server, so all the shares are on that.

    The shares that don't work are the ones in the profile (documents, start menu and desktop). The share to the shared area is mapped as a drive via GPO and works correctly. All the profiles have been binned and recreated. The documents are also mapped to a drive, but they don't work.

    The time is spot on with the server.

    Does anyone have any ideas about this? I found this post:

    Folder Redirection has stopped working

    but it doesn't seem to have sorted it.

    Check date, time and also time zones on both server and a few laptops ?

    Also have you got another server you could set some shares on and see if you still get the same issue?

    Where is the share? is it a Windows share or a Linux Nas box?

    Have you enabled NLA?

    If it is a Linux Box, try setting the following Reg key: HKLM/SYSTEM/CURRENTCONTROLSET/CONTROL/LSA/LMCompatibilityLevel REG_DWORD = 2

    Yup, got another server. It's an old one running 2003 which is currently just a print server. I can access shares from that fine.

    Timezones and time are the same on the server and laptop.
