Greetings!!!

I have some performance issue in one of our application.  It is a windows server 2003 Active Directory, SQL Server and application.

There is a lack.  So When i tracert, there is a delay and also when I tracert, it does not provide the computer name.  It just show the IP address of the computer.

Any thoughts will be highly appreciated.

Try
tracert -d (IP address)

The -d  option will suppress  reverse DNS lookups.
See if the speed changes.

Next I would suggest issuing the "IPCONFIG /ALL"  command
and check which DNS servers are in use.

Most likely what is happening  is one or more of the DNS servers in use are down,  or failing to get an answer for reverse DNS query for the IP address you are tracert'ing to.

It could be a DNS issue;  if the IP address is internal, it could be a local reverse zone config issue.

Try
nslookup www.google.com  (DNS Server IP)

for example; to test that  normal  Forward DNS is working.

To run a test DNS query of REVERSE DNS, using  the nslookup command

To check what the answer is to a reverse DNS  request of IP address  A.B.C.D

C:\> nslookup
> server  (DNS server IP)
> set type=PTR

>  D.C.B.A.in-addr.arpa


(Note the reversal of the octets)

If reverse DNS is operational  for  the range containing the IP being queried; a working  recursive  DNS server should give a timely reply to the reverse DNS request!



For any private IP addreses, such as RFC1918 addresses;  the DNS admin should have the DNS servers configured to be intercepting reverse DNS queries locally.
