Just be careful, make sure you have a good backup of everything.  When the updates in question are available as hotfixes and are not included in the usual regular updates is for a reason in my opinion, and Microsoft says that too.  If you are not experiencing any specific problems I would recommend you to wait. 

Also, my Win2003 server is telling me about the availability of SP2.  I don't know if the patches being discussed here are included in SP2 though.

True.  But I'm still perplexed at how fast my PCs are now running IIS locally with DNN, both 3.x and 4.x.  It used to be that when I logged in as Admin all the graphics at the top would take forever to load, one by one.  Now is instant, and in the past it didn't matter what cache settings you had.  I understand that it was actually an intentional limitation of the TCP/IP stack, so that you didn't use XP to host sites for production (right).

Now in the high end versions of Vista they removed those limitations for network connections and IIS actually.  I think that they decided to trickle down that policy to XP Pro and let developers enjoy that benefit after suffering with the slow IIS for so long (this was also the case for IIS on Win2K Pro).
