login script and batch file

I would like my login sript to execute a batch file for Windows 2000 and XP users only..

Here is an example of my current login script:

--------

@echo off


Echo off

\\svfile\tnsnames\updatetnsnamesoapps.bat

if #%OS%#==## goto WIN95
if %OS%==Windows_NT GOTO NT

:WIN95
net use H: /home



if exist p:\nt.txt goto END
if exist p:\ net use /d p:
net use p: /delete
net use q: /delete
net use x: /delete
net use p: \\svfile\PUBLICwest
net use q: \\svfile\eastinterconnect
net use x: \\svfile\common
goto END

:NT
if %windir%==C:\WTSRV goto END


if exist p:\nt.txt goto END
if exist p:\ net use /d p:
net use p: /delete
net use q: /delete
net use r: /delete
net use x: /delete
net use p: \\svfile\PUBLICwest
net use q: \\svfile\eastinterconnect
net use x: \\svfile\common
net time \\s_nw_sms /set /y

:END

---

I want to add a new statement for \\svfile\ittools\install.bat for ONLY 2000 and XP users... how can this be done?

thanks
