Enabling a "SHUTDOWN" option on Windows 2000 Logins
With Windows 2000 security defaults desktop installations allow a system
shutdown from the Ctrl-Alt-Del login and server systems do not. (Figures
- since normally you would not want anybody to close down the server
without permission).
However, there are circumstances where you want to amend this, so where
is the setting.
Select Control Panel, Administrative Tools, Local Security, Security
Settings, Local Policies, Security Options. (Phew! Easy once you know
where!). In the right hand panel you will have an option "Allow system
to be shut down without logging on" - this can be enabled or disabled.
While we are there, here are a few other interesting settings you might
want to explore:
Do not display last user name: useful in secure areas where you don't
want to give any hints as to valid user names, since a hacker then only
needs to guess the password.
Message text for users attempting to log on (also Message Title): Lets
you modify the text that a user will see in the login dialog.

"ARGLIST TOO LONG" - JUST WHAT DO YOU DO WITH TOO MANY FILES IN A FOLDER?
Advice for Unix users.
Wildcard expansion (globbing) is performed by the shell. There is a
limit of 5120 bytes (5k) for the environment and command line arguments
put together, in all versions of SCO Xenix and SCO Unix versions prior
to OpenServer 5 (more on OSR5 later).
So, if you ask for "ls *" in a folder with many files, (or long names)
then you can end up with the "arglist too long" message. Basically, it
has expanded all that "*" into a single command line holding each and
every filename in the folder.
There are a couple of routes to get round this, the simplest is switch
to using "echo". Why? Because echo is a built in command and does not
have the 5K limit. So you could use:
echo * | xargs ls
By the way, xargs takes the stdin list and fires up the command on the
right.
Instead of "echo *" you might want to try "find" which gives you much
more control over identifying files:
find ./ -type d | xargs ls -ld
Would find all folders and list them. Note though, find is recursive
and will find all sub-folders too.
OpenServer Release 5 makes two changes to cure this problem. The default
limit has been increased substantially (to 100k), which should by itself
fix almost all instances of "arglist too long". As well, it is now a
tunable kernel parameter, so if the default isn't adequate, you can
adjust it. One exception: /bin/csh still has a hard-coded limit to the
length of a line.

MEXICO UPDATE - MANAGING UNIPLEX.ALIAS
Ever moved an alias file by hand? No need to now.
In a point upgrade to Mexico - our Uniplex Mail to Exchange converter -
we have no added the facility to include alias entries from
Uniplex.alias.
This is especially useful for long distribution lists as these can now
be introduced into Exchange without error.
Mexico will process the uniplex.alias file for all multi-address entries
and produce an import list ready for Exchange. The whole process takes
about 5 minutes - and believe me a lot better than doing the job
manually!
Mexico has been used in organisations like Q8 Petroleum to migrate
thousands of users from Uniplex to Microsoft Exchange. As well as
handling user lists, it converts all mailboxes and can even translate
attachments as well.
Mexico is a must have for any organistion moving from Uniplex to
Exchange
FREE UPGRADES:
If you are a Mexico user - then please call or email for your free
upgrade. This upgrade is included in your site contract.

PRODUCTING SMOOTH GRAPHIC SELECTIONS
If you have a jagged selection - usually caused by using the magic wand,
or smart edge you can use masks to smooth the result.
Make your selection
Select Masks, New, Show Selection. You will get a tight mask around your
selection.
Now select Masks, Edit (you might also want to use Masks, View Mask).
Remove the selection (this will still leave the mask)
Select Gaussian Blur. Adjust the spread of the blur as required. You
will see a much smoother mask.
If the edge of the mask is too indistinct, you can adjust the Contrast
to tighten up the edge.
You can now re-create the selection from the mask, select Selections,
From Mask.
You now have a smoother selection, and one you have had good control
over the edge of the selection.

Yeah, but what if it's because the strong ones are all in people who
don't drink?
