Mapping drive from 2000 Advanced Server to 2003 Server

[Rico]

Hello.

I'm being unable to access drives shared by a Win2K Advanced Server, from
the client running Win 2003 Server. It seems to be an authentication issue:

User has not been granted the requested logon type.

There is no domain; I've tried accessing by IP_Address\username and
machine_name\username

On the Win2K Server I've used secpol.msc to make username be allowed to
access resources over the network, and even 'logon locally'

There are 2 Win2K Advanced Server machines and 2 Win2003 Server machines.
Win2K can see the other Win2K, and vice versa; and Win2003 can see Win2003.
But cross O.S resource sharing isn't working. Any input from you people to
help me out? Thanks.

Rico.

The form to use is machine_name\username where
machine_name is the machine sharing out the storage
and username is defined on that system and has been
grant the user right to log on over the network.
If all that is correct, then check that the machines share
an authentication setting, such as both allowing NTLM v2
with similar signing requirements so that they can negotiate
a way to handshake for the authentication.

Hi Roger,

Thanks. However, I couldn't find such a setting in secpol.msc
May I know how I go about checking that the machines share an
authentication setting for handshake negotiation?

look down in the Computer branch of policies, in the Windows
settings/Security settings/Local Policy/ Security Options
The specific policies are names somewhat differently in W2k
and W2k3, but look for the Lanmanager authentication level,
the minimum security level for NTLM, and also check and all
of the groups of settings with client and server versions ending in
always or if agrees or when possible. The two machines must be
able to find an agreeable combination based on the settings of these.
