All of the users are using XP-Pro.
Netware Client 4.91 sp4

I have in the Local Network properties "Show icon in notification area when
box checked (puts the two little computers at the left hand corner of the
task bar)

I have notice that it says I'm connected 10/00 but it also shows "attempting
to Authenticate"

Would this be something in the client or bad switch or what?

Does any one know?

Some users at times cannot get into the server, they relogon and everything
is fine

I would appreciate any ones ideals.
