How to Request Login over a peer network?

I have two Windows XP professional computers on a microsoft peer network.

If I access the network from a laptop whilst logged on to a user which
doesn't exist on the PCs then I get a different result:
- one PC asks me to logon
- the other shows the folders on the shared drives but does not allow
access to those folders

I would like to change the second PC to request a logon. Anybody know how
to do this?

thanks DAvy

Either the parent folder permissions are different or else the share
permissions are different. I suspect it's the parent folder permissions.
Examine both on each host machine, then align them.

One other possibility:

One of the XP Pro machines has "Simple File Sharing" enabled while
the other doesn't. When Simple File Sharing is enabled, all incoming
access to files is forced through the "Guest" user. When Simple File
Sharing is disabled, individual user authentication takes place with
a possible difference in access permissions.

John,
I thought that you had hit on it but I examined folder options/view and
both machines have 'simple file sharing' unchecked.

thanks though

OK. I had another thought.

The normal condition would be to ask for user/password.

So. Is it possible that you are already somehow connected to the
machine that does not ask for authentication? Perhaps a drive mapping
that reconnects on startup? Try this -- Before attempting to connect
to the machine that doesn't prompt for user/password, bring up a
command window on your laptop (start->run->"cmd") and enter the
command:
net use
Examine the result and verify that the computer you are trying to
connect to does _not_ show up anywhere on the resulting list. Windows
will only allow one authentication per connected machine, so if you are
already authenticated somehow, it will not ask for user/password.

If it does show up in the list, disconnect either from command line:
net use \\computer\share /delete
or right-click "My Network Places" -> Disconnect Network Drive...
(even if it is not mapped as a network drive)

Also, double-check that your laptop username does not exist on the
remote computer by bringing up a command prompt on the remote computer
and entering the command:
net user

Net Use does not show the computer that asks for a loggin; but has lots
of entries for the PC that does not

I disconnected all the network drives in "My Network Places". Net Use
then shows no network connections. But if I go to Windows Explorer/My
Network Places/Entire Network/Microsoft Windows Network/Workgroup/PCname
then all the network places still show up. If I click on one then I get a
message 'access denied' but no invitation to login. This persists even if
I log off and on again. Very strange!

Net User shows it doesn't exist on the remote machine.

John,
a little more testing shows that the differing behaviour between the two
remote machine also works in reverse, i.e. the remote machine that requests
a login is in turn asked for a login when it tries to access the local
machine. And the remote machine that doesn't request a login does not get
asked to login when accessing the local machine.

Hope that made some sense.

Now we're getting somewhere. This is the reason that the one computer
does not ask for login credentials. It is because you already have
established a connections to that computer.

It may be that you have stored username/passwords for that one
computer recorded under your login. These are stored by logged-in
user name so one test would be to create a brand new user on your
laptop, log in as that user and see if things are different.

Also, try the following article and see if it helps:

Not in a Domain in Windows XP"

One other thing to try.
After clearing all your connections to that machine, bring up a
command window and enter the command:

net use * \\computer\share /user:computer\username

where "computer" is replaced by the name of the computer you are
trying to connect to (2 places), and "share" is replaced with a
sharename on that computer. "username" is replaced with the username
on that computer that you want to authenticate to. The rest is typed
as shown. Keep the slashes (/) and back-slashes (\) straight. If it
works, it will ask you for the password of that user before
connecting. If there is a problem, the command line approach usually
provides a more usable error message.

I created a new user (which does not exist on the other two machines)on the
laptop. Was surprised to see in Windows Explorer/network/MS network/ listed
all the folders that had been accessed by an authenticated user on the
laptop! When clicking on the folder I get an access violation message.
Nevertheless, seems to be some kind of privacy breach cos can see what
another user has been accessing.

I think its time to give up!
