I have a single Windows 7 Pro 32b laptop being denied access to a specific share on a specific SBS server.
If any authenticated domain user account (including members of Domain Admins) attempts to access this specific network share from the device, they get the "You do not have permissions to access this share, please contact network admin" etc error.
All other shares on the server are accessible from this laptop and the problem share is accessible from any other computer on the domain.
1) gone through the permissions with a fine tooth-comb (Share permissions set to "everyone: Full control" and NTFS set to "Domain Users: Modify") as well as sharing/unsharing the folder, adding "Everyone: full control" to the NTFS permissions. Checking the "Effective permissions" for any given user seems to check out fine.
2) Removed and re-added the client machine to the domain
3) Checked for cached local machine passwords for the share/specific users
4) Checked for any GPs or other controls which may be denying access to a given resource for a given machine - can't find anything!
and I still can't fathom this one out!
