There are currently no logon servers available to service the logon r

[mvaldez]

I installed an hp netserver with w2k and I connected a workstation with w2k professional. I can see the server's name from my ws, but when I click on the server's name I got the following message: there are currently no logon servers available to service the logon request.
What I have done:

-I created a user account (I granted all the privileges I found)
-I created my workstation's name in the server
-I typed an ip address in the server
-I typed an ip address in my ws

It seems to be that I have no permission...

Thank you guys...
