Name already exists on network?

Maybe someone can help me out with this...

One of our servers is not viewable anymore through Network Neighborhood.
When checking the event log it tells me it cannot start the network because
a duplicate name already exists. It used to be NS1 and now I had to change
it to NS1a to start the network.

When I go into Network Neighborhood it shows the NS1 just sitting there like
its a Workgroup.

Any idea?
