Access denied to network drive between two Vista systems

[re_vogel]

I cannot access the network drives on two vista computers. One is 64 bit the
other is 32 bit. All permissions setup correctly (as far as I can tell) and
the drives can be networked but unable to access those drives from the other
system (Access Denied).

Do you have 3rd party security software?

AVG antivirus but no firewall/blocking software. I can see the other
computers drive and map it. I just can't access it. States "Access Denied" on
both systems

Excellent, thorough, yet easy to understand article about File/Printer
Sharing in Vista. Includes details about sharing printers as well as files
and folders:

http://technet.microsoft.com/en-us/library/bb727037.aspx

Problems sharing files between computers on a network are generally caused
by 1) a misconfigured firewall or overlooked firewall (including a stateful
firewall in a VPN); or 2) inadvertently running two firewalls such as the
built-in Windows Firewall and a third-party firewall; and/or 3) not having
identical user accounts and passwords on all Workgroup machines; 4) trying
to create shares where the operating system does not permit it.

A. Configure firewalls on all machines to allow the Local Area Network (LAN)
traffic as trusted. With Windows Firewall, this means allowing File/Printer
Sharing on the Exceptions tab. If you aren't running a third-party firewall
or have an antivirus/security program with its own firewall component, then
you're fine. With third-party firewalls, I usually configure the LAN
allowance with an IP range. Ex. would be 192.168.1.0-192.168.1.254.
Obviously you would substitute your correct subnet. Refer to any third
party security program's Help or user forums for how to properly configure
its firewall. Do not run more than one firewall. DO NOT TURN OFF FIREWALLS;
CONFIGURE THEM CORRECTLY.

B. For ease of organization, put all computers in the same Workgroup. This
is done from the System applet in Control Panel, Computer Name tab.

C. Create matching user accounts and passwords on all machines. You do not
need to be logged into the same account on all machines and the passwords
assigned to each user account can be different; the accounts/passwords just
need to exist and match on all machines. DO NOT NEGLECT TO CREATE
PASSWORDS, EVEN IF ONLY SIMPLE ONES. If you wish a machine to boot directly
to the Desktop (into one particular user's account) for convenience, you
can do this. The instructions at this link work for both XP and Vista:

Everything doublechecked. Still unable to access drive

Sorry. You've apparently got something set wrong but there is no way for me
to know what. Reading through your first post, you reference "network
drives". I was assuming that you meant local drives on other computers on
the network. Re-reading it I wonder if you really meant that you have two
NAS devices. If this is the case, check with the NAS mftrs. for firmware
updates and tech support. NAS devices run an embedded version of Linux and
may have an older version of Samba.

You can also try making a change in Vista to work with *nix systems:

Navigate to the policy "Network Security: LAN Manager authentication level"
and double-click it to get its Properties. By default Windows Vista sets
the policy to "NTVLM2 responses only". Use the drop-down arrow to change
this to "LM and NTLM ? use NTLMV2 session security if negotiated".

In Vista Home Premium, you won't have this tool so per Steve Winograd, do:

1. Run the registry editor and open this key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa

1. If it doesn't already exist, create a DWORD value named
LmCompatibilityLevel

3. Set the value to 1

4. Reboot

If you aren't using NAS devices, then you should probably have a computer
professional or knowledgeable friend come on-site to help you.

I'm sorry that I was unable to help you.
