Hi! I have a random problem with the workstations.
It began when we added the first OES2 server, all others are NW6.5SP7.

The problem is that when we click OK the client hang for about 1 minute then there's the message "the server has reinitialized the connection" (french translation) and there's no local login.
The SLP is Ok, and I can ping everywhere.

It is happening everywhere on different vlans, but just about 1% of the time, very random!

I've been able the grab the packets, but I cannot see the problem!?

The hang begin at #10753, it take a minute to have an ncp respond!

Is there someone that can see something?
I've attached all the log, there's 1 or 2 login the worked first, then the last lines are the login that hang.

thank you
Eric.
