I have a HP laptop that is able to login to IM just fine and has been

working great. Today they try and send a message and the CPU will go
100% then a messages comes back and says that it can not contact the server. I have removed and reinstalled, GroupWise, IM and Windows
messaging. This is an XP computer. They see all conneced users and a
can send them a message but the same thing happens with he tried to
to the sender. Anyone have any ideas where to look?

Thank you,
