| LOL. I talk to myself (a lot) and write a lot of stuff that I later erase
prior to sending. Through that mechanism, mostly anyone outside of me will
see the good 50% but some of the bad can slip through. :o) I have a strong
desire to not look like a complete dunderhead in public. I have been known
to say some stunningly stupid things though.

Or to put it another simpler way, mileage varies. What works very well for
me may not be in your best interest.
I would like to hear the technical details behind the SID issues from that
article though. Maybe I will follow the link. Though I doubt what I want is
there. Very little serious deep tech in that mag anymore. The tech stuff I
previously wrote for them they stopped putting in the mag and started
putting in their over the top highly overpriced "professional newsletters"
that were $100+ for 12 tiny little issues that looked like a small school
newspaper. joe

Don't get me wrong though... Sysprep/newsid, follow the process. I am
absolutely not telling people to image machines and deploy them without
cleaning them up. If you have odd things happening and are not following the
recommended processes, it is all on you and you get to take responsibility
for what you do. :)

I would like to see the details of what the issues are. Windows IT Pro mag
is a nice mag and all, but there is no real technical review of the
articles, you can say about anything you want to and I have seen several
examples. Ditto for Redmond Mag and SearchWindows*, etc.
I don't think the people actually test the stuff they say in a lot of those
articles though they try to state it authoritatively. -----Original Message-----

At the start of the GUI phase of installation each NT/2000 installation
generates a unique Security IDentifier (SID). If you then clone a
workstation each installation would have the same machine SID.
This is not a problem in a Windows NT 4.0 domain as users have a SID
generated by the domain controller and do not user the local workstation SID
for security. It IS a problem in a Windows 2000 domain as the local machine
SID is used in nearly all aspects of security and before migrating to 2000
you should resolve any duplicate SID issues which may have been caused by
cloning installations.

Taken
from http://www.sysinternals.com/Utilities/NewSid.html
under the SID Duplication Problem
Duplicate SIDs aren't an issue in a
Domain-based environment since domain accounts have SID's based on the Domain
SID. But, according to Microsoft Knowledge Base article Q162001, "Do Not
Disk Duplicate Installed Versions of Windows NT", in a Workgroup
environment security is based on local account SIDs. Thus, if two computers
have users with the same SID, the Workgroup will not be able to distinguish
between the users. All resources, including files and Registry keys, that one user
has access to, the other will as well.

Gary, Brian,
I do not use Sysprep on my images and have
yet to come across any problems, but there may be one big difference with my
images, before I ghost them or create the image I put the said machine into a
workgroup and then create image. After I have imaged a computer I log on
and change the Computer Name reboot and then join the domain with the new
computer name, should I be using Sysprep?
And Brenda I have experienced your problem
but I have never noticed the accounts actually being out of AD, anyways most
times for me a simple reboot works although I have had to actually ghost
computers in order to rejoin the domain because I do not have any local
accounts active on my computers in the school, makes it a little safer J but with that comes more
work L

Brenda,
FWIW: It happens to me when I clone
a workstation then try to join that workstation to the domain in order to
change the computer name. AD sees 2 machines with the same name, gives me
a notification and lets the 2nd one in. Then when the original machine
with that name logs in next time, it isn't seen on the network. Then I
have to do the same thing you did - with the original machine.
Then all is well again. Don't know if that will help, but it
might narrow down the problem some.

Subject: [ActiveDir] AD computer

Occasionally
computers will lose their account in Active Directory for no apparent
reason. Sometimes it is a computer that has just joined the domain, while
other times the machine has been a member of the domain for 2 years. The
computer can only be logged on by a local account (not a domain account).
To remedy this, the computer has to be disjoined from the domain, join a
workgroup, then join the domain again. As I am sure you all are aware,
this is not only time consuming, but very inappropriate to have to do.
Has
anyone else had this experience and how have you fixed it?
Thanks,
Brenda

| I can relate. I frequently do the 60 hr week thing, and as the senior of
the two IT people for our company, I do all the
design/planning/decision-making, as well as fix all the hard stuff the
other guy can't fix.
I have found that automating my repetitive tasks has helped a lot. I did
a few things to help my ability to work smarter rather than harder.
I set aside an hour a day for a while (at home, at work after hours,
wherever) and played with new tools; reskit, joeware, scripting,
whatever it took. That got me some confidence in using the advanced
tools.
I spent a bunch of time on this forum and the sys admin forum (sunbelt).
Lurking mostly, and contributing when time and skill allowed, but
frequently looking at a problem, making an estimate of the fix, and then
comparing my fix to the "experts".
I developed monitoring for all my production using What's Up Gold and
Dumpevt/grep. That allowed me to find most failures well before they
developed. I'd say better than 95% of the server problems I deal with
are things I find before the end-users know about them, which is how it
should be, IMO.
I've also trained my junior admin and handed off all the stuff I can to
him. It's hard to let go of some of it, but once I do and see that it's
getting handled, I relax. :-)
I think the bottom line is that until I took the steps necessary to work
smarter, I just kept working harder. Spending a bunch of time to improve
my skills and efficiency paid off tremendously. I don't do the 100 hour
weeks anymore. Spending 8 hours to develop workable group policies saved
me at least that much time per week with desktop configuration issues.
If you can get your boss to buy into allowing you some no-contact time
each week, you can use that to improve your skills/efficiency. You can
make the case to him/her that using a bit of your time will pay
dividends quickly.
Do whatever it takes to move as far from reactive mode as you can. I've
felt your pain; it's no fun...

Subject: [ActiveDir] AD computer
accounts being removed
Occasionally
computers will lose their account in Active Directory for no apparent
reason. Sometimes it is a computer that has just joined the domain, while
other times the machine has been a member of the domain for 2 years. The
computer can only be logged on by a local account (not a domain account).
To remedy this, the computer has to be disjoined from the domain, join a
workgroup, then join the domain again. As I am sure you all are aware,
this is not only time consuming, but very inappropriate to have to do.
Has
anyone else had this experience and how have you fixed it?

| No it is not possible to delete that account. (As far as I know) but there
are times when the account has been disabled thru a Policy (that is how I
disable it) and that program has not worked, I know it doesn't make a lot of
sense because why is the policy being enforced if it will not connect to the
domain but guess what sometimes it is like that, and if everything always
worked the way it was supposed to well then we wouldn't be needed now would
we?

You might be able to disable it, but IIRC, you can reset the password
and unlock/re-enable to account using the infamous bootdisk at:
http://home.eunet.no/~pnordahl/ntpasswd/
Shouldn't need to re-image.

| Well I would agree that is not a safe
practice for most but for my application where all Local accounts are disabled
I do not see a problem.
Taken
from http://www.sysinternals.com/Utilities/NewSid.html
under the SID Duplication Problem
Duplicate SIDs aren't an issue in a
Domain-based environment since domain accounts have SID's based on the Domain
SID. But, according to Microsoft Knowledge Base article Q162001, "Do Not
Disk Duplicate Installed Versions of Windows NT", in a Workgroup environment
security is based on local account SIDs. Thus, if two computers have users with
the same SID, the Workgroup will not be able to distinguish between the users.
All resources, including files and Registry keys, that one user has access to,
the other will as well.

| You can have collisions between a domain

when two machines have duplicate SIDs and one is DCPROMO™d and the other

a workstation then try to join that workstation to the domain in order to
change the computer name. AD sees 2 machines with the same name, gives me
a notification and lets the 2nd one in. Then when the original machine
with that name logs in next time, it isn't seen on the network. Then I
have to do the same thing you did - with the original machine.
Then all is well again. Don't know if that will help, but it
might narrow down the problem some.

Subject: [ActiveDir] AD computer
accounts being removed
Occasionally
computers will lose their account in Active Directory for no apparent
reason. Sometimes it is a computer that has just joined the domain, while
other times the machine has been a member of the domain for 2 years. The
computer can only be logged on by a local account (not a domain account).
To remedy this, the computer has to be disjoined from the domain, join a
workgroup, then join the domain again. As I am sure you all are aware,
this is not only time consuming, but very inappropriate to have to do.
Has
anyone else had this experience and how have you fixed it?

| I was referring to workstations not Servers,
who would even think of ghosting a Server? And here is the bottom line I have
been ghosting workstations for several years now at this site without using
Sysprep or anything like it, and it has caused me no problems, I have yet to
hear anything worth while on why I should be running sysprep on a workstation
in a Domain Environment where local login is not prohibited other than some BS
stuff from Wininternals or some other mag like that. So put your rolled up
newspapers away ( unless of course your going to be using it on yourself ) and
give me something worth while or concrete as to why I should be running Sysprep
in the mentioned environment other than NO NO NO NO BAD BAD BAD BAD you must
run sysprep.

You can have collisions between a domain

when two machines have duplicate SIDs and one is DCPROMO™d and the other

Well not really. The important SID
in question is the Domain SID and that isn't duped.
The domain doesn't care about the machine SID. It is still good
practice to newsid the machines though.
If the accounts are disappearing it is one
of two things
1. Someone is deleting it.
2. During the join process something fails
and the computer deletes the object out. I don't recall the details of this but
I do recall hearing it happen. It happens right after the failed join though,
you don't have to wait for it. I have also heard other people who don't
have enough rights report the account being disabled instead of deleted. I

| Hey Wook - though I agree it's a bad idea to do this, I've
always thought DCPROMOing a server to a new domain created a NEW domain SID,
which is totally unrelated to the server's SID. Or was it the other
way around (un-promoting a DC creates a new SID for the server...). Hmm
probalby the latter from what you write.
Would be good if you can find the error-message (saves me
time in testing this :-)

The main one in my mind is simply a support thing with
MS. I agree with how bad the info is out there on why people think it needs to
be done. It is easier to do it as you go then to actually really hit a real
problem that does impact you that has you running around your environment doing
it for all machines. So while I myself have mixed feelings on how much it is
needed you will NEVER hear me tell a customer or anyone else they shouldn't do
it.

Yep sorry, didn't
intend to say it wasn't a good idea. At some point the list will catch up and my
post that says that will show up. :)

Dozen
other reasons to run it. Not running sysprep is just a bad idea.
Thanks,Brian

Well not really. The
important SID in question is the Domain
SID and that isn't duped. The
domain doesn't care about the machine SID. It is still good practice
to newsid the machines though.
If the accounts are
disappearing it is one of two things
1. Someone is deleting
it.
2. During the join
process something fails and the computer deletes the object out. I don't recall
the details of this but I do recall hearing it happen. It happens right after
the failed join though, you don't have to wait for it. I have also heard
other people who don't have enough rights report the account being disabled
instead of deleted. I never verified personally either.

Gary,
Brian,
I do not use Sysprep on
my images and have yet to come across any problems, but there may be one big
difference with my images, before I ghost them or create the image I put the
said machine into a workgroup and then create image. After I have imaged a
computer I log on and change the Computer Name reboot and then join the domain
with the new computer name, should I be using Sysprep?
And Brenda I have
experienced your problem but I have never noticed the accounts actually being
out of AD, anyways most times for me a simple reboot works although I have had
to actually ghost computers in order to rejoin the domain because I do not have
any local accounts active on my computers in the school, makes it a little safer
J but with that comes
more work L

Brenda,
FWIW: It happens
to me when I clone a workstation then try to join that workstation to the domain
in order to change the computer name. AD sees 2 machines with the same
name, gives me a notification and lets the 2nd one in. Then when the
original machine with that name logs in next time, it isn't seen on the
network. Then I have to do the same thing you did - with the original
machine. Then all is well again. Don't know if that will
help, but it might narrow down the problem
some.
