Heard of Atomic Clocks? Or NIST ? Here is a tip on accurately setting your computer clock

Till yesterday I was using a separate third party utility to synchronize my computer clock precisely. I am not a timely person in all other aspects of life (not a good thing but have to be truthful !) to worry about time that too at atomic level but as it is with many things, it sounds like good a good idea to do it anyway! Thanks to National Institute of Standards and Technology, It has become much easier to do that via Internet. And there is no need for third party tool if you have bought WINDOWS XP Operating System. Just click on the time (right side of your START bar or panel) and click on INTERNET TIME tab. Select the time.nist.gov and click update now. Your are all set. Wait a minute your computer clock is still not that advanced. So you many need to synchronize again and again. But hey, we are in the computer world and who has time for This manual work. So I have a solution for you. OPEN registry editor ( I think you know how to open a registry.. Click START-RUN and enter regedit) and navigate to HKEY_LOCAL_MACHINE \ SYSTEM \ ControlSet001 \ Services \ W32Time \ TimeProviders \ NtpClient. In right pane, you would see "SpecialPollInterval". Double click and set a decimal number (unit is seconds) to the frequency with which you want to have the automatic synchronization carried out.
Also you can add many more time servers directly into registry because by default all that you can see is two time servers in the drop down list. List of many other time servers is available at http://www.eecis.udel.edu/~mills/ntp/. To add any other time servers, get details about the server and then navigate to [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\DateTime\Servers] and adding them into the list.

Do you know there are two command shell environments in XP ? which one is better ?

In Microsoft Windows XP Pro ( I think this must be true for HOME Edition, but don't quote on me), There is not one but two different command shell environment. One is the old one COMMAND.COM and other one is CMD.EXE. Both would do the job but they do it somewhat differently at a lower level. Which one is better ? I have noticed that CMD.EXE is much better in executing your commands. And this is true. CMD.EXE is the new command shell environment. that is better by design.So if you want to try out even your very old DOS apps, try it first in CMD.EXE. There is a very good chance that it will work and will work better than in your old shell.

Ever wondered how come you get into those HTML error pages ? Want to customize them ?

Some times, I type a webpage address and instead of seeing the page, see an error message. Do you know that all these error messages are stored in a DLL file. That is correct ! All of this message are burned into SHDOCLC.DLL file. Here is the syntax to see all of these error messages . If you want to see server busy error message type in Internet address field, res://c:\Windows\System32\SHDOCLC.DLL/servbusy.htm Similarly If you want to try out any other error message simply replace servbusy.htm by that html file (just the names) Here are some complete examples html files that you can try .
http_400.htm, http_404.htm, http_406.htm, http_410.htm, http_500.htm, http_501.htm, http_gen.htm, servbusy.htm, syntax.htm, navcancl.htm, offcancl.htm, policyerror.htm, policylooking.htm, policynone.htm, policysyntaxerror.htm, privacypolicy.dlg, preview.dlg, printerr.htm, printnf.htm, printnof.htm, printunk.htm, wcee.htm, ietext.bmp, ietext256.bmp, world.bmp, world256.gif, ie.gif, ie256.gif, orgfav.dlg, about.dlg, analyze.dlg, bidifind.dlg, docppg.ppg, error.dlg, find.dlg, findic.dlg, ieerror.dlg, imageppg.ppg, orgfav.dlg, and pstemplate.dlg
If you need to customize these messages, write an error message that you want to see as displayed and store it somewhere on your harddisk, open registry by going to START-RUN and entering REGEDIT and navigate to Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\AboutURLs and changing entries associated with various keys and provide complete path name to your own custom html file.

If you have a lot of RAM, do you really need swap file?

With RAM prices dropping so low ( I saw 256 MB SDRAM for $34 in COMPUSA on Jan 2nd,2002), more and more people are adding RAM to their computer. This is the best upgrade I would suggested to anyone. Well if you have 512MB or 768 MB or a whopping 1GB of RAM, you do not need a swap file (SWAP FILE is the concept of old dayw when RAM was too costly). Try this out. Go to My Computer and right click on properties and get into System Properties window. Go to Advanced tab and click on the Settings button for Performance group, click again on advanced tab and then click on change and choose NO SWAP FILE. I think you would see an improvement. If you don't like the change, follow the same steps and change SWAP FILE size to whatever you want (typically 1.5 * physical RAM). Also you can further gain by applying following changes in registry. Open Registry by going to START-RUN and typing REGEDIT. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Memory Management and look for DisablePagingExecutive. On my computer default value is 0. Set it to 1. This will stop paging act as well.

How to boost XP speed by by changing real time clock priority?

Open Registry by going to START-RUN and typing REGEDIT. Navigate to [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Contro l\PriorityControl]. If you see an entry by the name IRQ8Priority set it to a value "IRQ8Priority"=dword:00000001 if you don't then click on the right pane and add a new dword entry with given name.. IRQ8 is typically reserved for real time clock in most of the computers. Make sure thats the case (by going to device manager -> system devices -> system COMS/realtime clock -> properties -> resources tab , if it is set to another number try adding an entry with that number N as IRQNPriority) . Generally realtime clock priority boosting helps most but you are free to try others as well.

Reduce IO and increase turnaround which means faster computer !

Open Registry by going to START-RUN and typing REGEDIT. Navigate to [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Memory Management\IoPageLockLimit. Depending upon how much RAM you have, you can increase your diskcache size by entering a higher value in IoPageLockLimit. Typically your computer won't come optimized for diskcache and you can set to a value which works best for you by trial and error.Rule of thumb is to have a ratio of 1 or 2 for every 64K chuck. But try out various different values as each case would be a little different

How to avoid password entry at start up ?

Open Administrative tools in control panel and go to Local security policy.Select accounts and within that password policies. Set minimum password length to 0. This should be enough to stop password from being entered at startup.
I have received some criticism for asking users to set their password length to 0 and I agree to some of the potential security risks. Here is one better way to do it.

Go to START-RUN and enter "control userpasswords2" select the user the you would like to have auto logon set to and then uncheck "Users must enter a user name and password to use this computer". Ok out. Now you have to do one more thing. Go to START-RUN and enter "control userpasswords" and clicking on “Change the way users log on or off”, and unchecking both “Use the Welcome Screen” and “Use Fast User Switching”.
There is another way to get to the same screen. Try this to auto logon 1. At a command prompt, type: rundll32 netplwiz.dll,UsersRunDll 2. In the User Accounts dialog that appears, clear the "Users must enter a user name and password to use this computer" check box and click OK. 3. Enter the user name and password of the account you want to automatically log on.

Now Reboot and see it happen.

IMPORTANT DISCLAIMER: (Please make sure that you are doing this to user account and not administrator account. If you do this to administrator account or user accounts that have admin privileges and connect to Internet. and do not have a good firewall installed or enabled, your are exposing yourself to potential risks) XPTOOLS is not responsible for any such damage. *Also note that default user accounts created by XP are in admin group and have admin privileges so be careful.
