Maria,

It doesn't sound like you are using a seed file.  Or U456664 turned the
seedfile off.
You must be using a seedfile, since router loopbacks never show up in the
arp or interface tables of other routers.

Also, name conflicts, involving DNS, /etc/hosts, or both, can cause this.
If an otherwise correctly discovered router has a loopback interface that
sufferes  a name change to that of another router, Netview will sometimes
move just that loopback to the other router.  That will cause the next
interface in the interface list of that first router to become the selection
name of the router, and the symbol name will change too.

HSRP will only cause a problem only if a router gets discovered by an HSRP
interface.  You should never let Netview discover routers by HSRP
interfaces.
