Windows explorer stops repondiong

I configured my home network by the wizard and had
connections rpoblems, specially sharing the internet
connection. Then I manually configured the network and
fixed the internet connecgtion, connection to shared
printer is fine, but when I need to browse other drives
on the network and open My Network places or clcik on the
network drives in explorer, they stop responding and I
had to close them with task manager, After that when I
reopen My network places or windows explorer I can browse
the network drives normally.

Could anyone help me to fix this annoying problem, Why I
can not browse the network drives the first I try to
open them
