It’s possible that the Windows internal resolver is adding ‘.local’ to the domain name because there’s no dots in it.
nslookup wouldn’t do that.
To verify this possiblity, install ‘Wireshark’ (previously aka Ethereal) on your client machine and observe any DNS request packets leaving it when you run the
OK, further investigation on my own XP machine at home reveals that for single label names (i.e. “foo”, or “foo.”) the system doesn’t use DNS at all, and instead uses NBNS (NetBios Name Service).
Using a hint found at http://www.chicagotech.net/netforums/viewtopic.php?t=1476, I found that I was able to force DNS lookups for single label domains by putting a single entry reading “.” in the “Append these DNS
suffixes (in order)” in the “Advanced TCP/IP settings” dialog
I had this problem occasionally when using a multi-label name ie test.internal
The solution for me was to stop/start the dnscache on my windows 7 machine. Open a console as administrator and type
net stop dnscache net start dnscache
then sigh and look for a way to get a Mac as your principal desktop.
I have the same issue with IIS running on my home server, on the client machine a command like
ipconfig /flushdns usually solves the problem.
I had the same issue.
As pointed out by other answers ping and nslookup use different mechanisms to lookup an ip.
Chances are you are trying to ping a machine not on the same domain. When you ping the fully qualified name of the server this should then work.
PS C:\Users\Administrator> nslookup nuget Server: ad-01.docs.com Address: 192.168.10.20 Name: nuget.docs.com Address: 192.168.10.17
PS C:\Users\Administrator> ping nuget Ping request could not find host nuget. Please check the name and try again.
Ping works, using FQDN:
PS C:\Users\Administrator> ping nuget.docs.com Pinging nuget.docs.com [192.168.70.17] with 32 bytes of data: Reply from 192.168.10.17: bytes=32 time=1ms TTL=127 Reply from 192.168.10.17: bytes=32 time=2ms TTL=127 Reply from 192.168.10.17: bytes=32 time=2ms TTL=127 Reply from 192.168.10.17: bytes=32 time=2ms TTL=127 Ping statistics for 192.168.10.17: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 1ms, Maximum = 2ms, Average = 1ms
To fix this you will need to alter the DNS setting for the machine and add the DNS suffix to lookup.
- Control Panel\Network and Internet\Network Connections
- Network adapter -> properties
- IPV4 -> Properties
- General tab -> Advanced
- DNS Tab
- Select “Append these DNS suffixes (in order)”
- Add the required domain names
- Disable, then enable your network adapter (don’t do this on a VM, you’ll loose your connection, instead try ‘ipconfig /renew’)
I think this behavior can be turned off, but Window’s online help wasn’t extremely clear:
If you disable NetBIOS over TCP/IP,
you cannot use broadcast-based NetBIOS
name resolution to resolve computer
names to IP addresses for computers on
the same network segment. If your
computers are on the same network
segment, and NetBIOS over TCP/IP is
disabled, you must install a DNS
server and either have the computers
register with DNS (or manually
configure DNS records) or configure
entries in the local Hosts file for
In Windows XP, there is a checkbox:
Advanced TCP/IP Settings
[ ] Enable LMHOSTS lookup
There is also a book that covers this at length, “Networking Personal Computers with TCP/IP: Building TCP/IP Networks (old O’Reilly book)”. Unfortunately, I cannot look it up because I disposed of my copy a while ago.
Do you have an entry for weddinglist in your hosts file? You can find this in:
nslookup always uses DNS whereas ping uses other methods for finding hostnames as well.
I found a little bug in windows Server 2003 R2 EE.
you know that when you specify your IP address in the NIC (network connections), windows tells you that if you dont specify the preferred DNS server, it will put his own ip because it is an DNS server? well it doesn’t do that…
I fixed my problem writing the dns adress manually, instead of letting windows do it for me.
Try ipconfig /displaydns and look for weddinglist. If it’s cached as “name does not exist” (possibly because of a previous intermittent failed lookup), you can flush the cache with ipconfig /flushdns.
nslookup doesn’t use the cache, but rather queries the DNS server directly.
It worked for me..
If you can ping the FQDN, look at how DNS devolution is set up the PC.
Winsock API which MS ping will automatically use the FQDN of the client PC if append primary and connection specific DNS suffix is checked in TCP/IP advanced DNS settings. If the host is in another domain, the client must perform DNS devolution.
Under XP TCP/IP advanced properties DNS, make sure append parent suffixes is checked so that the ping request traverses the domain back to the parent.
I think the problem can be because of the NAT. Normally the DNS clients make requests via UDP. But when the DNS server is behind the NAT the UDP requests will not work.
I know it’s not your specific problem, but I faced the same symptoms when I configured a static IP address in the network adapter settings and forgot to enter a “Default Gateway”.
Leaving the field blank, the network icon shows an Internet connection, and I could ping internal servers but not external ones, so I assumed it was a DNS problem. NSLookup still worked, but of course, ping failed to find the server (again, seemed like a DNS issue.) Anyway, one more thing to check. =P
FYI – I have been struggling with this issue for the past 3 hours. tried everything, flushing DNS, using a proxy, resetting catalog using netsh and clearing the routes. nothing worked so i decided to give windows restore a try, I did it using a windows cd -> repair -> system restore and it worked ! couldnt find any solutions online so i figured id post it
I also encountered this issue. No Windows application (except Chrome) could access the internet. I found it was a duplicate IP on the LAN. I changed the local IP, and everything, including ping, started working again.
I found the problem doing an
and it listed
IPv4 Address. . . . . . . . . . . : 10.10.0.20(Duplicate)
I also had this problem on a Server 2012 R2 VM joined to my local AD domain. I eventually solved the problem by taking the VM off the domain and re-joining it.
