when i am running DCPROMO on this BDC to remove active directory from it..it
gets so far and then gives me the error below:

The Operation failed because:
the attempt to configure the machine account <server> on server
<server.domain> failed
"Not enough quota avaliable to process this command"

any research i have found on this error says it may have to do with a page
file size. I have increased that and i am still getting this error. Please
give me any advice you have...thanks so much in advance.
 
The information supplied isn't enough to provide much assistance and there
are no PDC's or BDC's with Active Directory loaded on them. So I'm making
the assumption this is really a Domain Controller. If you could find any
EventId's in the Event log this would help or run some diagnostics against
this domain.

Otherwise if you need to remove this dc from the domain you will have to do
a dcpromo /forceremoval (Which should demote the server) but before you do
you should move any fsmo roles off of this server. To check to see if it
holds any from a command prompt type in: netdom query fsmo (The server
tools if not loaded can be installed from the server install cd). If this
dc holds any roles they should be transferred before you do the demotion.
Next do the demotion and follow that up with a cleaning of the metadata of
AD.

To run diagnostics against your Active Directory domain:

If you don't have the tools installed, install them from your server install
disk.
d:\support\tools\setup.exe

Run dcdiag and netdiag in verbose mode.

If you download a gui script I wrote it should be simple to set and run. It
also has the option to run individual tests without having to learn all the
switch options. The details will be output in notepad text files that pop
up automagically.

The script is at http://pbbergs.dynu.com/windows/windows.htm, download it
and save it to c:\program files\support tools\

Just select both dcdiag and netdiag make sure verbose is set. (Leave the
default settings for dcdiag as set when selected)

When complete search for fail, error and warning messages.
 
the link isnt seeming to work, just brings me to an error page. Could you
let me know another way to get the script? The server i am trying to demote
is a backup domain controller.
 
sorry i was actually able to get to the site after some time. I have
downloaded it and saved the script in the folder specified. I also have the
tools installed. When i run the script and im given the prompt to select the
tests to run i cant find either dcdiag or netdiag in either of the drop down
menus..would you mind pointing me in the right direction?
 
They should just be check boxes. No drop down boxes that say dcdiag and
netdiag.

i have run the tests and everything showed up fine and everything passed..my
next question is: If i were to force the removal of AD using dcpromo
/forceremoval is there any harm in doing it this way? should i be awear of
anything before i run this forced removal?

thanks
 
No.

Go ahead and do the forceremoval followed by the metadata cleanup

Follow that with another set of diag tests
