BAT/CMD scripts are very much helpful to do a monotonous job automatically and sometimes the outputs of the batch script file are very much required. We can generate log file from batch file, but we can’t get the 100% log within batch file, so I was looking for a tool which generate log files from a batch script. After a few search, finally I found a tiny utility called wtee.exe on wintee.

To use it properly, I have created a batch file with which u can execute any batch script, and after executing the batch file it will automatically archive the entire output log, also there is an option to send mail notification with the output file as mail attachment (optional). For sending mail notification I used blat.exe from www.blat.net.

Again, as per business requirement, we are looking for some free internal (LAN) chat solution. There are some free LAN chat tools available but most of them are failed to detect multiple VLAN, only working fine in single VLAN.

But we need something which can be implemented on more than 50 branches across India. So we are looking for a free chat server. There are some chat servers available, but none of them support Active Directory (LDAP) authentication.

Suddenly we found a solution, actually it’s not a single solution, it a combine solution of PHPBB3 and AJAX Chat.

Sometimes it’s not possible to remember a specific weekly job to perform. So if we can make it as scheduled job to do the same, it will be better. There will be not such risk. Just take my example, I have to clean our office common shared temporary folder on every Sunday, but I am not in office on Sunday. So, I have two options to do the same, first, I have to call our DCO Support and instruct them to get the job done, and if I go with this option there will be lots of dependencies, or else I have to create a script which will do the job automatically.

So I decided to go for second option. With second option I have to make sure following things should be perform.

• I just can’t delete all files & folder from temp drive, coz there might came some requirement to recover files from last week temp drive(Yes, everyone aware of the temp drive policy). So, I have to copy all the content of the Temp Drive to a different location.
• I have to create a folder with date stamp, eg. Folder_date (tempbkp_23-09-2009). So, I have to create a specific date variable.
• After copy all content of the temp drive to other location, I have to give Everyone – Read only permission to that folder and then have to share that folder as well.
• Delete all files and folder from temp drive. Yea, as per my knowledge, there is no such command available on windows by which I can delete all files and folder from a specific folder or a specific map drive. (So…..time to think some alternatives)
• Now the critical part, on next scheduled date, this script will automatically delete last backup folder, and create a new folder for latest backup.

And finally I made it with considering all above requirement without using any third part toolsJ. And as of now it’s working properly, check out the script bellow.

A simple script for automatic System State backup where you can easily set backup retention period and it also send you an e-mail notification after completion.

Recently after installing FAX Server on our site, we are having some problem with opening received FAX file from user desktop. FAX files are .G3N/.G3F/.CTL of which .G3N and .G3F file can be opened in Windows Image Viewer and .CTL file can be opened in Notepad.

But the problem is, users have to make it their own, or we have to do it manually on all workstation across all branches. But it’s almost impossible to do so, so we have to think about some global solution.

Another requirement, now customer need to disable default windows Print Screen function on all of their user desktop,

So, we started our searching again, and easily we able to find out how to disable print screen on windows by importing following registry.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout]
"Scancode Map"=hex:00,00,00,00,00,00,00,00,03,00,00,00,00,00,37,e0,00,00,54,00,\
00,00,00,00

So, again we start working to create a custom adm file. As because this is a HKLM key, so we need Privilege to import it into registry, and only way to do so is to apply some policy via Computer Configuration, whit which we can force policy on each computer not on individual user.

But suddenly we discover that ADM files don’t support reg_binary values, so we have to find out any other alternatives.

Option Explicit
Dim objItem, colItems, objWMIService, strComputer, objShell
strComputer = "."
Set objShell = CreateObject("WScript.Shell")
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set colItems = objWMIService.ExecQuery("Select * from Win32_OperatingSystem",,48)
For Each objItem in colItems
                If InStr(objItem.Caption,"2000") Then
                                'Add your line here for 2000
                                objShell.Run "regedit", 1, True
                End If
    		If InStr(LCase(objItem.Caption),Lcase("XP")) Then
                                'Add your command line here for 2000
                                objShell.Run "calc", 1, True
                End If
		If InStr(LCase(objItem.Caption),Lcase("2003")) Then
                                'Add your command line here for 2000
                                objShell.Run "notepad", 1, True
                End If
Next

with above script, on Windows 2000 it will execute regedit.exe, on Windows XP it will execute calc.exe, and on Windows 2003 it will execute notepad.exe.

You can change the file as you wish..
