Equipment
The following equipment is required for this exercise:
• A computer running Windows 2000 Professional
Scenario
The system administrator needs to create a script in the startup folder that will display on
the users desktops when they log on to their systems. To experiment with writing scripts
for that, practice with a sample script that will be created in this lab.
Procedures
In this lab, the student will create and execute a Visual Basic Script and place it the start
menu.
Step 1: Writing the Script

If UserName = "" Then
Greeting = "Why won't you tell me your name? That's not very nice."
ElseIf UserName = "go away" Then
Greeting = "That's not very nice."
ElseIf Username = "who's asking?" Then
Greeting = "I asked you first."
Else
Greeting = "Hello, " & UserName & ", it's a pleasure to meet you."

If UserName = "Steve" Then
Greeting = Greeting & " I like the name Steve."
End IF
End IF

MsgBox Greeting

3. Save the document as “Greeting.vbs”
Note: If the student needs to edit changes after saving, have them change the extension
to .txt.
To change the file back to a .vbs scripts go to the following folder:
C:\WINNT\system32
In this folder associate the Greeting.vbs file with the wscript file.
Step 2: Executing the Script
1. Navigate to the folder where the file was saved and double-click on it.
2. Do not type anything in the box and click OK. Notice what message is displayed and
how it corresponds to the entry in the text of the script.
3. Click OK.
4. Double-click the script again and this time type go away in the box. Notice what
message is displayed and how it corresponds to the entry in the text of the script.

5. Click OK.
6. Double-click the script again and this time type who’s asking in the box. Notice what
message is displayed and how it corresponds to the entry in the text of the script.
7. Click OK.
8. Double-click the script again and this time type Alice in the box. Notice what
message is displayed and how it corresponds to the entry in the text of the script.
9. Click OK.
10. Double-click the script again and this time type Steve in the box. Notice what
message is displayed and how it corresponds to the entry in the text of the script.
Step 3: Executing the script when the system starts
1. Navigate to the Startup folder. Go to C:/Document and Settings/All Users/Start
Menu/Programs/Startup. Drag the script file that was created in Step 1 and place it
into the folder.
2. Restart the computer and the script should execute automatically when the system
reboots.
Troubleshooting
Troubleshooting a Visual Basic Script or can be difficult since the text has to be 100
percent accurate for the script to execute properly. Review the script before it is saved
and executed to make sure that is written correctly.
Reflection
Scripts can serve a variety of functions and can be very helpful to a system administrator.
The script that was written in this lab was fairly simple script compared to how complex a
Visual Basic script can be.
1. What are some other uses for scripts?
2. Where might they be useful and where might they cause harm?
