Are you using ADS kerberos authentication in your network?
If so, your kerberos might be broken.
When you are using the hostname, the client tries to authenticate via
kerberos ticket. If this fails, it's over.
When you are using the IP address, the client does not get a ticket for
the server (requesting a ticket for "192.168.10.11" instead "hostname" -
but the ADS server only has a ticket for "hostname").
After that, the client uses NTLM authentication. If this succeeds you
become transparently connected to the server.
To verify, if this situation matches yours, you could examine your level
10 logs or - better - have a look at the network traces.
