Andres,

ReadyState==3 means the data is being downloaded. That means on W2K machine 
the download is taking significantly longer. Have you tried to accessing the 
"url" from the IE address bar from W2K and XP to see if you can repro the 
delay in IE.

Also on W2K which msxml dll(s)  is(are) installed and what is the version 
number? Please provide the same info for XP too.
