NAS Segate 440 Server can be resolved by host name from clients, only with the IP

I have had this machine in our network for about two years, recently had to replace two hard drives and reset it the unit back to defaults and reloaded the most updated firmware. After resetting back to defaults I put it back on our network with the same name, same share name and same static IP, however most of my PCs (50) cannot resolve the name, I have to type the IP in order to access the shares in this NAS. If I rename this machine to a different name other than the previous name then it works OK, the issue is that I have our POS pointing  to this machine to pull reports, so changing the name will be a little challenge in terms of labor and confusion for our users.

This NAS is in a workgroup because not all my PCs are in active directory.

Thank you in advance for any help!

Is the DNS record still in the DNS server, as well as the reverse DNS record? It wasn't dynamic by any chance? Also can try "ipconfig /flushdns" on the clients for good measure ...

I found a record in the DNS server pointing to a different IP with the same host name, I deleted it.

Should I recreate a new record with the host name and IP? This NAS in not part of AD, it is in a workgroup

Yes, I would make a static A record so that it can't change anymore, it doesn't matter if it belongs to AD or not, DNS can be seen separate in this case.

After you've changed it you might need to flush the dns cache on the clients.

interesting how some PCs are letting me see this machine with the name, but others cannot see this machine with the name, I have to type the IP in order to see the shares.
Mario G.SupportAuthor Commented:
I added the the static A record and flushed the DNS, but still no luck. Is there something in the local machine that can be reset to to access this machine with the name, not the IP?

What does nslookup tell you, the same?

nslookup <ip-of-NAS>

Open in new window

nslookup <name-of-NAS>

Open in new window

Might have to flush a few times or even reboot...
Mario G.SupportAuthor Commented:
the nslookup returns the correct name for this machine. I can ping the name and the IP and the result is correct for IP and name. I will try flushing the dns couple of times and will reboot the machine to find out. Will update soon.

Zephyr ICTCloud ArchitectCommented:
Ok, that means DNS should be ok... Let's see what more flushing and/or a reboot tells us.
