NSLOOKUP works, but IP still showing as system name

[Sean Murray_1]

When doing a lookup, I can resolve both name to IP and vice versa.
But about 7 servers are not showing up by their name, but rather their IP address.
Tried removing one and adding again, but no dice.
Any ideas?
Thanks

I'm having the same problem Sean and even got one of our network chaps to remove all reverse lookup PTR records from DNS and put them back in again (he loved me for that) but still no joy.

I am also having the same problem. I have checked DNS and have not found any problems. Deleting the record does not help, because it comes back the same way.

ipconfig /flushdns ?

[Sean Murray_1]

Tried flushing. Then got DCOM errors like mad such as:
"DCOM got error "Class not registered " from the computer dwnt1.sherwin.com when attempting to activate the server"
and
"DCOM was unable to communicate with the computer using any of the configured protocols."
But I can ping the machines in each error and use NSLOOKUP both ways.
So, now to figure this mess out.

One thing I did to fix this (though not pretty) was to add the servers into the HOSTS file on the server as the names you want it to appear as. Then delete the servers and re-add them and see if they are named properly.

I'm not sure where it happens but I believe one of the identification processes updates the info on the IM screen.

Make sure the DNS is correct, both forward and reverse lookups. Check that you're not having one return a sub-domain, e.g. looking up 10.10.10.10 might return server.ad.mycompany.com but you're just doing a lookup of server.mycompany.com to compare.

Then allow the various discovery / identification processes to go through. I've got all my devices recognised and we have a mixture of AD and Unix based DNS which offers loads of variety for confusion. I've not had to resort to using a local hosts file, I've found that tends to cause more problems later on, e.g. you click on the device link and cannot get to the page.
