Fix for Ping request could not find host "FQDN of server" Error
I can ping by their IP address but not by their name
ping 192.168.1.3 --works
ping familypc --doesn't work
Ping request could not find host ___ Please check the name and try again
net start DNScache
nslookup does not use the same references as ping
nslookup will quiery the DNS server, on the AD domain controller your security was authenticated on.
Ping simply asks DNS give me the ip so I can ping it.
Their is no record in DNS for a myhost PC. But the code within the AD DNS schema has a refernce for a nslookup so you are returned the address of your authentication server..
If you invoke nslookup and put a x in front of it, you will get a > prompt. Type in a question mark at the prompt and you can see the switches to get the info you need with nslookup.
On Windows 2000 and later, if a request to your primary DNS server times out, it switches to the secondary DNS server and stays with it for a period of time. However, nslookup always connects to the primary.
Take a look at this article and be sure to read the part about caching negative responses.
Note This article refers to the client portion of DNS. Do not use this information for making changes to DNS servers.
- net stop dnscache
- sc servername stop dnscache
Note The overall performance of the client computer decreases and the network traffic for DNS queries increases if the DNS resolver cache is deactivated.
The DNS Client service optimizes the performance of DNS name resolution by storing previously resolved names in memory. If the DNS Client service is turned off, the computer can still resolve DNS names by using the network's DNS servers.
When the Windows resolver receives a positive or negative response to a query, it adds that positive or negative response to its cache, and as a result, creates a DNS resource record. The resolver always checks the cache before querying any DNS server. If a DNS resource record is in the cache, the resolver uses the record from the cache instead of querying a server. This behavior expedites queries and decreases network traffic for DNS queries.
You can use the Ipconfig tool to view and to flush the DNS resolver cache. To view the DNS resolver cache, type ipconfig /displaydns at a command prompt. Ipconfig displays the contents of the DNS resolver cache, including the DNS resource records that are preloaded from the Hosts file and any recently queried names that were resolved by the system. After a certain time period, the resolver discards the record from the cache. The time period is specified in the Time to Live (TTL) associated with the DNS resource record. You can also flush the cache manually. After you flush the cache, the computer must query DNS servers again for any DNS resource records previously resolved by the computer. To delete the entries in the DNS resolver cache, type ipconfig /flushdns at a command prompt.
Although subnet prioritization does reduce network traffic across subnets, in some cases you may prefer to have the round robin feature work as described in RFC 1794. If so, you can disable the Subnet Prioritization feature on your clients by adding the
I'm hoping this will also clear up the weird sudden-loss-of-shares and exchange issues
I incremented the serial the last time i made DNS changes. I made the above-suggested zero-neg-cache registry change. I have rebooted the machine and ensured all settings are current and policies are being applied.
DNS resolve problem with ping but not nslookup
windows XP SP3
my PC was not able to resolve DNS with most internet software
I tried pinging google and it also fails.
Ping request could not find host www.google.com. Please check the name and try again.
But nslookup can still work
*** Can't find server name for address 192.168.0.1: Non-existent domain
*** Default servers are not available
Addresses: 126.96.36.199, 188.8.131.52, 184.108.40.206, 220.127.116.11
Ping isn't going to work with many of the external host sites, so this is normal. If you can do an nslookup on a site, then dns is resolving correctly.
