Win98?  WTF?  Get an OS a bit more in line the times. :-)   Sound works
flawlessly for me with Win2k and WinXP guests.

I use USB devices without any problems.

Did you install the VBox Guest Additions?  If not, you are missing a
lot.

VBox probably wasn't designed to do some of those things, perhaps.  I've
found VBox's guest networking to be quite configurable.  Read the user
manual for more info.

Not enough info to answer that question.  Do you want to install samba
on the host and access shares from within a Windows guest?  Or do you
perhaps want to SMB share a folder in the Windows guest and mount it on
the host?  What's your host OS?

I print from a VBox guest to a network shared printer, as well as
directly to other network printers.  Are you trying to print from the
guest to a printer attached to the host?  If so, what kind of printer
and how is it attached to the host?  USB?  LTPx?  Serial?   Again, more
info will help in getting you correct answers.
