Hi,

I have configured DNS in linux machine.

In linux client machine i checked using nslookup it's giving proper output.But when i tried in Windows client machine,It's giving following error

C:\Documents and Settings\yal2361>nslookup 192.168.0.220
Server: www.ycsmumldap.com.0.168.192.in-addr.arpa
Address: 192.168.0.220

Name: www.ycsmumldap.com.0.168.192.in-addr.arpa
Address: 192.168.0.220

C:\Documents and Settings\yal2361>nslookup www.ycsmumldap.com

Server: www.ycsmumldap.com.0.168.192.in-addr.arpa
Address: 192.168.0.220

DNS request timed out.
timeout was 2 seconds.
Name: www.ycsmumldap.com
Address: 192.168.0.220



please let me know, what and where is the problem

Hi,

From the above looks like you missed the trailing dot at least for the NS record of the 0.168.192.in-addr.arpa zone. If it works on linux, but not on windows, you should flush the dns cache:

hi,

I flushed the DNS,Though I am getting same problem.

Hi,

Are you sure it's working on linux and both computers are using the same nameserver as a resolver?
Also posting the 2 zone files could be of help

Regards

yes, I am sure it's working Linux.


Forward zone file:

$TTL 86400
@ IN SOA www.ycsmumldap.com. root.www.ycsmumldap.com. (
1997022700 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
IN NS www.ycsmumldap.com.
1 IN PTR www.ycsmumldap.com.

www IN A 192.168.0.220



Reverse Zone File :

$TTL 86400
@ IN SOA www.ycsmumldap.com. root.www.ycsmumldap.com. (
1997022700 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
IN NS www.ycsmumldap.com.
1 IN PTR www.ycsmumldap.com.

220 IN PTR www.ycsmumldap.com.

Next time please use CODE tags for better readability.
You have an "error" in your forward zone. The PTR RR has no reason to be there.
Here is the forward zone file, with a current serial and blank spaces where needed:
Use this, reload bind and test from linux and windows with:

I have done which you told....now also i am getting same error in windows which i have pasted below.In linux i am getting proper way.

Windows

ycsmumldap.com nameserver = www.ycsmumldap.com.

check my post and tell me.

You didn't increase the serial, so the changes are not taken into effect. Also I don't understand why you get a timeout, but then nslookup works. Check if there is a firewall on server that blocks port 53udp/tcp
Note that you can also add an A record for ycsmumldap.com if you want, like
