first off did you install sp2. because with prob 1 there is a reg fix for the # of connections.This is mainly for P2P apps, or you can try this
Make sure your logged on as actually "Administrator".
Start->Run->type gpedit.msc
Expand the "Local Computer Policy" branch.
Expand the "Administrative Templates" branch.
Expand the "Network Branch".
Highlight the "QoS Packet Scheduler" in left window.
In right window double-click the "Limit Reservable Bandwidth" setting.
On setting tab check the "Enabled" item.
Where it says "Bandwidth limit %" change it to read 0.
Effect is immediate on some systems, some need to re-boot. This is more of a "counter
what XP does" thing. In other words, programs can request up to 20% of the bandwidth be
reserved for them, even with QoS disabled.


problem 2

I would go into internet options and del windows temp files, cookies, temp internet files, then go into objects and remove any objects you find. then change your security to low. and see if you can download MS virtual Machine
or you can get sun java from here
