Cannot authenticate machine ...

I am having the very same issue.  But also have not resolved it.

I recently realized that my roaming profiles were set up
incorrectly.(Originally, they were located in the HOMES share
\\%m\%u\profile)  I created a separate share named profiles.
\\%m\profiles\%u) and now I get the same error.  If I reboot the
workstation, users are able to login, but I've asked everyone to reboot when
they have finished using the workstation in order for everyone to login
without an error.

I am going to try changing the login script to map /persistant:no option on
my drive mapping to see if it makes a difference.  I let you know.

Subject: Cannot authenticate machine ...


I'm running Samba 2.0.7 on SuSE 6.3, kernel 2.2.16

I'm using samba as a PDC, authenticating NT 4 (srv pk 5) clients. I have no
problem setting up new NT clients and users to authenticate with samba, the
problem is with machines that have already been setup.

Now, the next step here is unclear to me, but basically the client machine
no longer authenticates with the samba PDC. Whether it happened when I
stopped samba, or changed a password.

The username still authenticates fine. Upon NT login, I get the error

"The system cannot log you on to this domain because the systems computer
account in its primary domain is missing or the password on that account is

To get around this problem, I login to the NT client as Administrator, move
the machine out of the "Domain" and into a "Workgroup", reboot the machine
... change it back to the "Domain" again, and I get the "Welcome to <X>

The I login as the user again, fine, except NT now creates a new profile for
that user, ie <username>.000 in c:\WINNT\Profiles ... and when I try to
start Outlook (2000), I get the error "Cannot start Microsoft Outlook". If I
login as Administrator I _can_ start Outlook.

Now, the get the machine to login to the original profile, I edited the
registry where I found the reference to <username>.000 and changed it to

So, the crux of my problem is getting Outlook to work again!!

Has anyone seen this problem???
