We just had a new server set up and am now trying to login but continually get the Tree or Server cannot be found error. Although when selecting the tree/context/server through the Advanced tab of the login screen, everything is displayed correctly. The client machines are a mix of win98/3.4 and 2000pro/4.9 and all are getting the same message. All can ping the server. Here is the weird part... you can login from offsite by using the IP, but not from here in the building. I then figured it was a routing problem with the Linux Box we use for DHCP. But, I bypassed the box altogether and connected a WS to the top layer switch (which the Server is connected to as well). Still getting the same error when trying to log in. What can I check next?
