windows xp 64 bit and windows update issues

Hey,

I'm getting an error number: 0x80072EE7. This workstation has windows xp pro 64bit installed. It's a brand new dell precision 670 and i just turned it on and i'm getting this windows update error. We do have an Intranet in place and windows 2003 server. No proxy server and it should be open.

So, my question is, is there some kind of compatibility problem here between windows xp 64bit and windows update? Or, perhaps windows 2003.

thanks!
