Computer loses network connection

[TVEngineer]

Windows XP Pro SP2, using static IP
Some programs, when shutdown, continue to appear running in Task Manager,
sometimes several copies.
Also, computer loses network connectivity - can still ping all computers on
the network, but can not connect; workgtoup finds no connection.
Full shut down and restart restores connectivity until the next time it
shuts dow.
Suggestions as to where to start looking?
TIA
