This week I was operating outside my usual area of expertise; I needed a CGI
(Common Gateway Interface) script for an autoresponder project. Now Guy knows
very little about CGI scripts and This Week's Secret is the CGI code made me
feel like a beginner. I wished that there were more remarks or comments to help
me understand the purpose of the script I was adapting.
So, I have taken to heart this problem of beginners needing explanations in
scripts, and this week I have put in lots of comments to explain what each
section is about.
Calculating IP Address
ranges is a black art, which many network managers solve by creating custom
Excel spreadsheets. IPAT cracks this problem of allocating IP addresses
in networks in two ways:
For Mr Organized there is a nifty subnet
calculator, you enter the network address and the subnet mask, then IPAT
works out the usable addresses and their ranges.
For Mr Lazy IPAT
discovers and then displays the IP addresses of existing computers.

There are many learning points in this script
a) Simple mapping network drive method - MapNetworkDrive
b) The logic which disconnects K:\ drive if it is already connected. People
often ask me how to check or disconnect a network drive.
c) For, next loops
d) If, then, else statements
Instructions:
Copy the lines following 'Script starts up to 'Script ends.
Paste the script into notepad.
Make changes to the value \\alan\home
Remember to save with a .vbs extension.
Double click to test the script
If you like it, then adapt it and assign it to your users
'Script starts here.
' VBScript by Guy Thomas
'Purpose of this script is two fold:
'Firstly, it maps the K:\ drive to \\server\share
'Secondly, if the K:\ drive is connected it disconnects it!
' The next line creates the Shell or environment for the commands - do not alter
Set WshShell = WScript.CreateObject("WScript.Shell")
' The section sets the variables. Note the pattern variable = value
' You may change the variable names if you wish to check your understanding.
Set GuyNet = WScript.CreateObject("WScript.Network")
Set CheckDrive = GuyNet.EnumNetworkDrives()
' Be very careful with the DriveLetter, the value must be a CAPITAL letter
DriveLetter = "K:"
' You must change the VALUE \\alan\home, unless you have a server called alan
RemotePath = "\\alan\home"
' This section deals with a For ... Next loop
AlreadyConnected = False
For i = 0 To CheckDrive.Count - 1 Step 2
If CheckDrive.Item(i) = DriveLetter Then AlreadyConnected = True
Next
' This section uses the If = then, else logic
' This section tests to see if the Drive is already mapped,
' and if yes then to
disconnect
' WshShell.PopUp is not strictly necessary
If AlreadyConnected = True then
GuyNet.RemoveNetworkDrive DriveLetter
GuyNet.MapNetworkDrive DriveLetter, RemotePath
WshShell.PopUp "Drive " & DriveLetter & "Disconnect, then connect
successfully"
Else
GuyNet.MapNetworkDrive DriveLetter, RemotePath
WshShell.PopUp "Drive " & DriveLetter & " connected successfully."
End if
'Script ends here
Guy Recommends: A Free Trial of the Network Performance Monitor
(NPM)
Solarwinds'
Orion performance monitor
will help you discover what's happening on your network. This
utility will also guide you through troubleshooting; the dashboard will
indicate whether the root cause is a broken link, faulty equipment or
resource overload.
Perhaps the NPM's best feature is the way it suggests solutions to network
problems. Its
second best feature is the ability to monitor the health of individual VMWare
virtual machines. If you are interested in troubleshooting, and creating
network maps, then I recommend that you take advantage of Solarwinds' offer.

the Network Performance Monitor.
These week's tip is to place comments in YOUR scripts. In particular, put
remarks on the PURPOSE of the script, and the role of each section. The HOW the
script is done should be apparent from the variables and the methods.
1. Map home drive
2. Remove
Network Drive
Each Litmus test is fun, yet has a serious learning point. I am sure that
there will be at least one test that will suit you. This week's litmus test is:
Professionals put comments on the PURPOSE of the script
Amateurs do not use comments in their scripts.
