You connect and log in, but the server responds with a user-defined
error message 20000 ("No Error") and then disconnects.  i'm not sure
if that's a message without an error or an error without a message.  

Since you know it's Sybase, you might try TDS 5.0. Perhaps maybe it
could be the server might be configured to reject 4.2 connections, or
treats them oddly.  It's been over a decade (two?) since Sybase made a
4.2 server.  

Otherwise I'd contact my sysadmin and ask what the significance of
message 20000 is.  

HTH.
