I have an iPod 30Gb which updated to 1.3 without problem on WinXP, and another which doesn't update on Win2K. Win2K doesn't have a built-in firewall and I don't have any third-party firewall installed on it. So the port issue you just mentioned shouldn't be at stake.
So, to get to the bottom of this, I just wasted a couple hours trying a host of things. I fired up Wireshark (freeware protocol network analyzer), here's the bottom line:
1. While running the built-in iTunes "Network Diagnostics", Wireshark does show that iTunes communicates with the following remote services:
www.apple.com.akadns.net
a227.da1.akamai.com
phobos.apple.com
The result of that test says connection active: no, Connected: no, etc. Red dot on the middle test.
2. When I click on the Update button in iTunes' iPod section, Wireshark doesn't show
any HTTP request, or any other type of remote request, for that matter. This means iTunes simply
never accesses the update site.
3. I don't think any port is blocked in Win2K (although I read somewhere that disabling some Windows services can close some ports). Another block could be made router-side (either local router or ISP), but as I've already mentioned, iTunes has no trouble accessing the update site on my XP machine, and they're on the same router; the only difference is, the Win2K laptop is plugged into an Ethernet cable, the XP laptop is on wireless.
So, where the explanation given to dealyb is valid because of the company's firewall, it doesn't seem to apply to me.
More investigations needed. If anyone wants to pick up from there and provide additional data... This is exceedingly annoying.
