In our list of "CLI workaround for Windows XP", a missing command is SLEEP or WAIT. For fixing this I suggest you two solution, first is simply a batch workaround using PING command, the second solution use the Windows Server 2003 Ressource Kit tools.
With PING you can produce a fixed delay by testing the loopback address. This can be really usefull if you don’t want (or if you can’t) install extra software.
# Doing an approximative pause of 60 seconds
PING -n 61 127.0.0.1>nul
Second way is to install the [Windows Server 2003 Resource Kit tools] from microsoft.com. You will get a SLEEP.exe that will do all the requested stuff.
