Ping take long time

[Tomasz Skorża <t.skorza@xxxxxxxxxxx>]

Hi

Could you have any idea why AS400 take long time to resolve host name to 
IP address?

What is incorrect setup in tcp configuration that it lokks like:

ping 'IT3' >>>> Time sent  . . . . . . :   11:42:45
Verifying connection to host system IT3.PRIMAFARMS.PRIMAFARM at address
  10.1.0.98.  >>>> Time sent  . . . . . . :   11:43:00
PING reply 1 from 10.1.0.98 took 0 ms. 256 bytes. TTL 128.
PING reply 2 from 10.1.0.98 took 6 ms. 256 bytes. TTL 128.
PING reply 3 from 10.1.0.98 took 0 ms. 256 bytes. TTL 128.
PING reply 4 from 10.1.0.98 took 0 ms. 256 bytes. TTL 128.
PING reply 5 from 10.1.0.98 took 0 ms. 256 bytes. TTL 128.
Round-trip (in milliseconds) min/avg/max = 0/1/6.
Connection verification statistics: 5 of 5 successful (100 %).

When use IP address it's ok - Why resolving host name take such long 
time? What is wrong in my DNS setup?

                        Change TCP/IP Domain (CHGTCPDMN)

 Type choices, press Enter.
 Host name  . . . . . . . . . . . 'AS400P'
 Domain name  . . . . . . . . . . 'COMPANY.COMPANY.INTERNAL'
  Domain search list . . . . . . . *DFT
 Host name search priority  . . .   *REMOTE       *REMOTE, *LOCAL, *SAME
 Domain name server:
   Internet address . . . . . . . '10.1.0.1'

"AS400P" it is host name of our AS400 on DNS server - 10.1.0.1

Our system is V5R4.
