Dns name resolution

1.check the DNS server event log for the error code

2.check the name resolution inside the dns service (using loop back) go to

strt->run>dnsmmgmt.msc

in dns console right click the server name,then select launch nslookup

then it will show something like this

Default Server:  pc1.google.com
Address:  192.168.2.201

then its sure that dns db and services are working properly other wise it will disply like this

*** Can't find server name for address 192.168.2.201: Non-existent domain
Default Server:  UnKnown
Address:  192.168.2.201

if u got this error then check the forwarder for appropriate host record..

3.After that check the name resolution in interface by

start>run>cmd>nslookup

Microsoft Windows [Version 5.2.3790]

C:\Documents and Settings\Administrator>nslookup
*** Default servers are not available
Default Server:  UnKnown
Address:  127.0.0.1

if this error occurs then maybe its problem of the interface tcp/ip configuration.

Add correct Preffered DNS preferrably first add server ip as p.dns itself.(its own ip)

then clear the service cache and interface cache using the command ipconfig /flushdns.

4.then recheck the dns using nslookup in interface...u will get

Microsoft Windows [Version 5.2.3790]
(C) Copyright 1985-2003 Microsoft Corp.

C:\Documents and Settings\Administrator>nslookup
Default Server:  pc1.google.com
Address:  192.168.2.201
