Glad to help. Did you give the DisableDHCPMediaSense key a
try? I worked out that the reason why this fixes the
problem is that the builtin *wired* NIC takes ages to boot
up when this key is enabled and the wired NIC isn't
connected in to the network. If you disable the wired NIC
the DisableDHCPMediaSense key doesn't help. It's a good
fix for the mean time though.
Which all backs up my hypothesis (and the one from the
wireless newsgroup) that Group Policy is just timing out.
Regarding the support incident, I'm just trying to
persuade them to give me a free support incident. I used
one of my two free XP incidents to raise the issue, but
the guy responded and said that the problem was with
Windows Server 2003 instead of XP. I know that the bug is
in XP, not 2K3, but he is just an XP standalone support
guy. The 2K3 team is probably better placed to fix the
problem. So I'm asking him to provide me with a free
incident for 2K3... I'll let you know how I get on. Don't
really want to splash out £80 on a paid support incident...
