connection problem

Hi to all,
in our organization we have server 2003, xp pro & win98se
workstations. i'm having problem to connect to the win98
workstations from the xp computers. i'm receiving error
massage:
"An error occurred while reconnecting "share name"
microsoft windows network: the local device name is
already in use. this connection has not been restored."
but i can connect to the xp workstations from the win98
and use all the resources that are shared.
anyone has any ideas?
thanks for advance
