I experience some strange problem with "Cannot access Tree or Server".

On my laptop that is connected to network using wireless, has been working
ok for a long time. But suddenly someting happens that the Client can't
access Tree or Server.
I can Brows the Tree, but cannot browse Context.

If i wait 5-10min then i can login without problem.

Is there some settings on connecting-timeout?

Client is the latest with the latest patch; NW4.91SP2 + patch
Server is NW6.5 SP3

It seems that after client 4.91, all this "Tree or server"-msg start. We
never had this problem before.
