Get computer name as variable to use in vbs script.

I have the following script below. I didn't write it. It finds Storage
groups, mail and public stores and paths on exchange 2003.
But it starts with a dialog box asking the user for tha name of the
server.
I want to have it run automatically unattended.
I want to get rid of the first two lines and define 'strServer' as a
variable that the script can find no matter what the name of the
server I put it on.

For example:

strServer=getTheNameOfThisServer.

So that I can use strServer later on in the script. How do I do that?
Thanks

strServer=InputBox("What is the name of the Exchange
Server?",strTitle,"TANK")

Have a look at the wsshell.ExpandEnvironmentStrings method of the
WScript.Shell object. There is a complete example in the downloadable help
file script56.chm. The computer name is available as %ComputerName%.
Alternatively you'll find the computer name under the Wscript.Network
object.

I added this to the top of the script

Set wshShell = Wscript.CreateObject( "Wscript.Shell" )
WScript.Echo "HOSTNAME: " & wshShell.ExpandEnvironmentStrings
( "%COMPUTERNAME%" )
WScript.Echo "DOMAIN : " & wshShell.ExpandEnvironmentStrings
( "%USERDOMAIN%" )
WScript.Echo ""


strServer=wshShell.ExpandEnvironmentStrings( "%COMPUTERNAME%"

Thanks for the feedback. Note that the following will work too:

wscript.echo wshShell.ExpandEnvironmentStrings("User=%UserName%,
PC=%COMPUTERNAME%" )

There is also the WSHNetwork object ...

Set WshNetwork = CreateObject("WScript.Network")
WScript.Echo "Domain = " & WshNetwork.UserDomain
WScript.Echo "Computer Name = " & WshNetwork.ComputerName
WScript.Echo "User Name = " & WshNetwork.UserName

Once you capture the name of the computer using any of the forementioned methods, how do you read the first 3 characters of the name?

For example, I have a script that I want to run on specific clients. The hostname on those clients start with the city of where they are located.

L-A-pcname
S-F-pcname
N-Y-pcname

I am looking to not only capture the name but do an if else statement so that it reads the first 3 characters of the hostname and based on the city let it install what is needed.

In this case I want L-A-pcname so I am thinking

IF %computername% ISEQUAL "L-A"
continue with script
ELSE
GOTOEND
