Question (QA 192) - Reset profile
on Windows NT
I lost my profile on Windows NT (or it is corrupted). Who can reset it ?
Answer - Any authorized administrator can do it, including the Computing Helpdesk (78888) who have been granted these privileges.
To see the list of authorized people:
Start - System Management - Nice NT Domain Admin. - Reset local administrator passwordand then click on
"show authorised": you will find all accounts that have the required privileges for this, including
The procedure to be followed by the administrator is then:
"NICE NT Domain Administration"(which had been added in the Domain tools list) in:
Start - System Management - NICE NT Domain Administration
The tool only deletes the server copy of the profile and administrators still need to delete manually the local copy. The recommended way to delete the local copy is to log in as a local administrator and use the utility in
Control Panel - System - User Profilesselect the user account, and press the delete button. This will delete all the registry entries associated to the profiles.
\profiles\is not enough and you run the risk of creating multiple profiles with the same name and extensions like
.000, .001, etc.
Question (QA 204) - Visual
Studio and Visual Basic on NICE
Could you please clarify the puzzling situation with different versions of Visual Studio, VC++, Visual Basic on NICE?
Answer - Today we have two versions of Visual Studio available on our NICE servers:
1. Visual C++ V5 and Visual Basic V5
They come as two separate packages and can be installed via
8-Software Engineering, Development, Visual C++ (or Visual Basic)The service
pack 3(icon 2 in both groups) for this version has to be added after installing the main product(s).
Applications developed under VC++ and VB mostly require
additional components to run properly (e.g OCXs and DLLs). For
applications developed with
Visual Studio 5, all these
components are already pre-installed on NICE, so the applications
compiled by the user will run on any NICE machine.
2. Visual Studio 6
This single package (including VC++ and VB) should be installed from the following path:
\\ntinfo01\vol2\Visualstudio6Enterprise, run 'setup.exe'Afterwards the service
pack 3from VS6 should be added from
\\ntinfo01\vol2\VisualStudio_Servpacks\Vssp3, run 'setupsp3.exe'Attention: Since the VS6 required components are not distributed on NICE, version 6 compiled applications will not run. The user has to deliver the required OCXs,DLLs and registry settings with his applications. In other words, he has to create a package. This can be easily done for VB applications using the
'Package and deployment wizard'in the VS6 tools program group. For C++ programs, you can use the
'Depends'tool to find the dependent components. In any case, packaging applications will become the standard on Windows 2000 and is the only way to distribute your application(s) on large scale.
Question (QA 227) - Default
How can I "force" my PC to open certain files (e.g.
Netscape instead of the default
Answer - By default, the browser used
by the PC is
Internet Explorer. To change it to
2 More applications
0 Set default browser Netscape
Question (QA 262) - NICE space
I need about 400MB disk space on my
directory (I am dealing with a lot of graphics). Actually I
have about 300MB of used space. The Helpdesk gave me an extra 50
MB, I got confirmation, but nothing happens. Why?
Answer - Most probably you have reached the "hard-coded" upper limit of 300 MB which cannot be over-ridden by the Helpdesk anymore and a manual intervention (from the NICE team) is needed.
Question (QA 265) - NICE server
How can I see on which NICE server(s) I am attached to?
Answer - From the DOS prompt
Start - Applications - 12) either type the command
net use or

'cut'. The field
'master'window. Close it.
Question (QA 181) - Login scripts
I accidently erased my home directory contents: is there a way I can re-initialize my login scripts (files
.profile,.cshrc,.login and such)?
Answer - First note that your complete
directory from last night is available online in the
/afs/cern.ch/ubackup directory corresponding to your AFS
/afs/cern.ch/ubackup/a/abcd for login
abcd) so you might be able to copy back the contents
If that is not sufficient then the command
"uco" can be used on all UNIX central systems (type
Question (QA 194) - CPU time
exceeded in batch job
I submitted a batch job in the RSPLUS cluster and it finished due to CPU time exceeded. For this reason it did not copy in my directory the files created in
$WORKDIR. Is there a
way to retrieve these files?
Answer - Unfortunately not: unless the user explicitly specifies to keep some files in the work directory, all files - except the standard output - are deleted when the job terminates.
If files were kept, they could be copied back by the user
with a simple
rcp command, i.e. in your case:
[rsplus08] ~ > rsh rsbat001 ls -l /pool/lsf/pilar/170289_135917 total 32 -rw-r----- 1 pilar t2 13552 Nov 4 12:02 941588516.170289.out
Question (QA 195) - Linux machine
What is the procedure to shutdown a Linux machine? Can I just power it off?
Answer - From the machine :
<CTRL> <ALT> <F6>keys altogether, then you should get a console prompt. Log as
root, then execute
userid, then as
root, then execute the
Question (QA 208) - GNU

Answer - This is apparently a bug which
has disappeared with GNU
make 3.78.1. Since
end-December 1999 it had been installed on all platforms in ASIS
and the problem has disappeared on all central platforms at
Question (QA 219) - LXPLUS and
I want to run a batch job on the central Linux cluster, shall I run the job on LXPLUS or LXBATCH ?
Answer - LXPLUS/LXBATCH is managed in a similar way as RSPLUS/RSBATCH:
Question (QA 220) -
"xlsbatch" on LXPLUS
When I run the command
"xlsbatch" on LXPLUS I get a
core-dump, while on RSPLUS it displays the job status as it
Answer - There is a known bug on Linux
with LSF programs using X core dump (such as
"xlsbatch") when these programs print a warning message at
startup. This can happen if there are not enough colours available:
then the command
"xlsbatch" can crash or not depending
Netscape is open or closed respectively in the X
session. It can also crash when there is a message for missing font
(or any other warning message).
"xlsbatch" for Linux will be upgraded as
soon as CERN will receive a fix for it. Meanwhile it can still be
used provided that there are enough colours available in the
colormap when launching it. Alternatively, equivalent LSF line
bhosts / bsub / bqueues / etc.) can be used
Question (QA 225) -
I'm having trouble staging tapes. When I try to stage in a tape with the
"stagein" command, it fails with an
"invalid user" error:
stagein -v LT0097 -q 1 Ze20 STG11 - invalid user: 6919So it looks like I don't have permission to stage atlas tapes.
Answer - The first thing to be checked
is that the users has 2 accounts (login) on
and the ATLAS Work Group Server
CMS_WGS for CMS staging).
Question (QA 182) - Strange
characters in Word document
I find very strange characters in my Word document which make it difficult to read (e.g. all spaces contain these characters). However, it's perfectly ok when I print (the characters are not printed then).
Answer - While you view or edit a
document on the screen, you can display characters such as
tab characters, spaces, and
that don't appear on the printed page. (For example,
Word uses arrows to represent
and dots to represent spaces.)
To see if you added an extra space between words, typed spaces instead of a tab character, and so on:
Options, and then click the
Nonprinting characters, select the check boxes of the characters you want to display.
Allcheck box instead of selecting each individual check box, and deselect it when you want to get rid of them.
Question (QA 184) - Installing
Internet Explorer 4
I tried to install Internet Explorer 4 from the
Start Menu (
it fails when trying to install the components. All the items are
marked with a red cross and I get the error message that the
installation failed. Nothing more.
Answer - In the last few months NICE system people have noticed PCs having corrupted registry settings preventing MSIE4 or MSIE5 from being installed. They checked that this problem does not come from NICE itself (otherwise they could have fixed it for everybody).
The only workaround to this problem is to do a full re-install of Windows/95 before installing MSIE4. Once this is done the user should not have any further problems.
Question (QA 185) - Internet
Which version of Internet Explorer is supported by NICE?
Answer - MSIE4 has been replaced by MSIE5. This is the only version you can install from NICE. but people who use MSIE4 can continue to do so.
Please note that MSIE3 does not work correctly with the current NICE nor with numerous Web sites around the world.
When users complain about MSIE, it is important to know
which version they run with:
Help menu - About.
Question (QA 190) - Directory
browsing from the Web on NICE
I would like to be able to do a directory browsing from the Web of the directory (for example) :
\\srv1_home\usr11\HOME\USER\MyDocs\What is the way to do it? Can I make my "Public" directory browsable too?
now the "root" of all files accessible from the web to be the "www"
folder in your home directory. Thus if you try to retrieve
http://nicewww.cern.ch/~USER ,it will try to get
j:\www, not just
The same situation exists with directory browsing requests. If you
http://nicewww.cern.ch/~USER/abc/ in your
browser, you will get:
j:\www\abcif directory browsing is enabled in
default.htmfile if directory browsing is disabled (and the file exists, of course).
Concerning the "Public" directory browsing: Unfortunately, you can not make contents of your Public folder available from the Web. Your web space is mapped to your j:\www folder, for example
http://nicewww.cern.ch/~USER/ will show you contents of the j:\www folder http://nicewww.cern.ch/~USER/foo/bar/ - contents of the j:\www\foo\bar.To enable directory browsing you have to put a nicewww.ini file into the j:\www folder, containing the following lines:
[NiceWWW] EnableDirectoryBrowsing = 1
This is all explained in:
Question (QA 199) - Default
What are the filenames usable to display a default Web-page ?
Answer - On
home.cern.ch the sequence of files which are searched for in
a directory for is the following (in order of precedence):
NB: The extension
.shtml is used for
server parsed files. For more information please have a look at
Question (QA 210) - Priority for
How can I ensure that people using search engines on the Web and looking for "my type of information" will find it at the top of their list?
Answer - As stated in the the
Infoseek manual (
you can put the following line in the
HEAD section of
your pages (especially in the home page):
<META name="keywords" content="MY_TYPE_OF_INFO, RELEVANT_KEYWORDS">Like that, the search engine will index your page giving a higher rate to these keywords, making your page appear higher in the result list, if the search was on these keywords.
N.B. You can read more on metadata at URLs:

Question (QA 217) - Password
Would you please explain to me how I can introduce a password on my home page?
Answer - If the page is in AFS and
home.cern.ch then one should know that
protections are not allowed (in principle) on that server. For
other hosts running the Apache Web Server (e.g.
wwwinfo.cern.ch) a typical
.htpasswd (file for private page protection) extract can be
found in a previous CNL, at URL:
Question (QA 189) - Colour problem
In order to run
"xwpick" with Exceed, I
had to change the default "Video" setting into
"PseudoColor" mode (instead of
which is the default).
An unexpected feature is that it then changes the colours in the output. What can be done to avoid this problem?
Answer - This is a bug in Exceed and we still expect a proper solution from Hummingbird's. However it seems that you can solve the problem by changing the "Display Properties" settings from 16 bits planes to 8 bits planes:
Start --> Settings --> Control Panel --> Display --> Settings -->The bug is the following: if the Windows 95 color depth is 16 while the server is using only 8 planes (PseudoColor) - setting required by
xwpickto work properly - the
XGetImage()call capture 8 planes, but not those used by the X server itself. This can easily be seen using the standard
xwd/xwudprograms from the X11R5 distribution.
