Error Creating a new cluster on windows 2003 Server EE SP1

Hi,
I'm trying to install cluster service on a Windows 2003 Server Enterprise
Edition SP1.
I've configured Network and Disk.
When I try to create a new a new cluster for the first node, I receive this
error:
Found an existing cluster or node with the name "pippo.mydomain.com". Choose
another name.
A cluster cannot be created with the specified cluster name because that
cluster name is already in use. Specify a different name for the cluster.
I try to change netbios name but it does nothing.(NETBIOS name pippo does
not exsist in mydomain.....i try to use net view \\pippo)
Can You help Me ?
Tank you.
Have you tried to create this cluster before? Chances are that you still
have a DNS entry that needs to be flushed. All Address and Pointer records
for this host/IP address combination need to be flushed before you try and
reinstall.
Sincerely,
Anthony Thomas
