Networking in VPC 2004

I have VPC 2004 (not server) and I currently have my Virtual Machines set
up to network peer-to-peer with my home networked Real Machines. I only
have this done so I can learn (for school) how to make settings in the
different OSes for networking and this was the easiest way for me to do
this. Anyhow, is there a limitation as to how many folders you can share
on a Virtual Machine? I have a VMC running Windows XP-Pro SP2 and I've
been trying to learn how to set permissions for sharing. Currently my home
network just allows Everyone to access all shares. When I set the VMC to
only allow certain users to access its shares, it would only allow one
drive or one folder to be connected to, not more than one. I get an error
saying that I don't have permission to access it, even though I set the
permissions in the VMC to allow the user to access. Even if I have the VMC
set to allow Everyone to access, as I do my home network, I can still only
access one shared folder from another networked computer, not more than
one. Is this a shortcoming of VPC? (I hope I made this clear enough.)
Thanks!

Patty

I'm quite possibly wrong here, but (IMHO) the limitation is probably an
Operating System issue, and not necessarily Virtual PC. It would depend
on what Operating systems are being used in both the host computer and
the Virtual Machines.

Also, in the Operating System, if a user is logged in (at least in my
experience) then that is the only user that can access the shares. What
I mean by this (an example, if you will) is..

On my Host machine, I'm logged in as Patrick Dickey. If I log into a
Virtual Machine as Administrator, I can't access the shared
files/folders on the host machine. Likewise, I can't access the shared
files/folders on the VM (from my host machine).

Before taking my reply as a definitive answer, I would wait and see what
the other posters will tell you. Most of them have more expertise in
Virtual PC and Virtual Server then I do. I'm just offering my reply as
a possibility.

On my network, all the permissions are set to Everyone and all computers

Windows Logon or whatever (no client for Micorosoft Network logons), the

Windows XP Pro SP2 and VPC machine is also Windows XP Pro SP2. Virtual
computer has a User set up using the same logon name as the host computer
which is also set up as an Administrator account. From the host computer I
can access a share on the Virtual Machine... only one shared folder, but
not more than one. I just checked the host computer. The Virtual Machine
can access the folders that were shared previously, but no new ones I've
just set to share. When I unshare a folder that I am told is inaccessible
on both the host machine and the Virtual machine, I am told that one user
is connected, but no one is really connected since I got the error that the
share cannot be accessed but in Computer management it shows one client
connected to that share. Huh? If they can't access it, then why are they
connected? I do not have this problem with any of my other OS computers
(98SE and ME) only the XP Pro ones. I'd like to know what's going on here,
perhaps I should move this discussion to XP Networking. Thanks.

Hi Patty,

Look at the setting on the computer you created the share on. Is it
possible you limited the number of users that can connect at one time? If
you did then that would explain why no more than one connection can connect
at one time.

Hope this is it.

No, users are not limited. In the XP Network NG we think that this

even if you set your access permissions to Everyone on the Sharing tab, it
does not carry over into Advanced Permissions on the Security tab. Once
you add Everyone there (as it is on my originally shared files before that
update was installed) then the files share fine. So, I'm going to play
with it a bit and see what I come up with in my Virtual Machine.

I may came to the thread too late.
I never expect setting share permission will automatically set security
setting.

The effective share access has always been a function of the share
permission and the actual security permission. security permission tend to
limit share permission.

Depending on environment, in general I don't use everyone when I don't have
to even for share permission. As that allow listing of shares available to
uses that has no business knowing existinence of such shares and also
clutter up the network neighbourhood. Maybe that is just my preference but
I tend think it is logical to use access based on need to know basis.

I know I am coming in late in the thread, but I wanted to let you
know that I had exactly the same problem on one of my machines.
I don't remember what security update did it, but one day I could
set the share to everyone, and everyone could use it, the next
day, they couldn't. If I remember correctly, I had problems
rolling back from the update as well.

There are so many variables, it can be frustrating. Good job on
tracking down the cause.
