First of all, I would like to say great product! Helps us alot since we manage hundreds of PCs.

Just a quick question on the host name

When we scan an entire subnet, there are duplicate host names. The IPs are alive, but they are registered with a different host name, on the scanner there are 4 to 5 entires all with the same host name.

Also, sometimes the host name is totally wrong.

How do we correct that?

Thanks

I don't know, it's possible there is some sort of cache or another application is interfering.

Try typing tracert x.x.x.x where x.x.x.x is the IP address of a problematic host and see what it says under Tracing route to YYY.

If the name is also incorrect, the problem is not in the network scanner.

I am seeing the same problem but can concur with Andrew that this is not a Netscan issue. I did as suggested and the tracert returns the same info that netscan does. When I do a nbtstat -a, it returns correct information. I'm still looking into the cause as I have checked everything on the workstation and can find no misconfiguration in the network settings.

Try restarting the DNS client service, it may help.

Any virtual hosts?

Is there a 1:1 correspondence to ip:hostname?
I.E., if you have >1 hostname per ip address that might be a confusion.
Might be able to jigger your dns records.

Yes there is 1:1 IP vs Hostname.

I tried restarting the DNS on my machine, same result.

I tried flushing and regsitering DNS, same result.

Is there any other option I could tweak?

You might try
ipconfig /flushdns
run netscan
ipconfig /displaydns

post the results
