I haven't encountered this problem myself - I've never tested using roaming
profiles - but one potential cause for this is that IE stores configuration
information and cached files within the profile. If it's a roaming profile,
that storage area will be on some server on the network, rather than on the
local machine. I'd guess that there might be all kinds of performance
problems with using the default configuration of Microsoft applications,
such as IE and Outlook, within roaming profiles.
You might be able to solve this by configuring IE to store files on the
local machine, in a common location that will be available on any machine on
which a roaming user might log in (like c:\temp). Of course, you'd lose some
caching that way, when a user logs in on another machine later. This
solution sounds like it'd probably be more trouble than it's worth, though.
