fileserver problem, "network name no longer available"

We replaced our two OLD servers with two new oned with 2003 on them.

Now I have a problem with the fileserver. When I try to get a big file I
get the message "network name no longer available".

The fileserver is also a DNS server and I've check the configuration and
it seems ok. I can ping computers by their namnes, surf on Internet and
so on.

I can upload files to the fileserver, download is only possible for
small files.

I really don't know what to do now. I still have the old fileserver
running and it works fine.

Can someone please point me in the right direction.

Thank you for your time.
