Network stand still
**this was posted in another forum I suspect wrong one moved here **Smilie
Hello all. Let me qualify my question by saying that I am struggling with how to ask the question I am semi green but have no issue reading up if pointed in the right direction. Please be gentle!

A RHEL server 6.2. Hosts a statistical application that has some web apps and batch programming interface.

Problem:
Lately we moved offices.
  1. Now logging in via PuTTy via ssh was taking long so a poweruser set useDNS No that speed up login
  2. Issue: Once we start our application (web app) login speed is fine but any action that requires a response such as navigating, open file, it hour clocks and either ends in error, or in some cases after 5 minutes renders back the requested item.
    • RAM is 65 GB, 45GB is free (from Top)
    • Load at most 1.35 usually around .5 avg.
    • Dedicated to host one application
    • At most 2-3 concurrent sessions expected but see only 1
    • tracert was 1ms
    • Ping replies w/o data loss
    • Putty session -ssh- connects in seconds
I have run some commands and their output are listed below

Code:
[rsas@lazer ~]$ host -t a lazer.aii-3.com
;; connection timed out; trying next origin
;; connection timed out; no servers could be reached
[rsas@lazer ~]$ host -t ns lazer.aii-3.com
;; connection timed out; trying next origin
;; connection timed out; no servers could be reached
[rsas@lazer ~]$ host -t mx lazer.aii-3.com
;; connection timed out; trying next origin
;; connection timed out; no servers could be reached
[rsas@lazer ~]$ host -a lazer.aii-3.com
Trying "lazer.aii-3.com"
;; connection timed out; trying next origin
Trying "lazer.aii-3.com.aii-3.com"
;; connection timed out; no servers could be reached
[rsas@lazer ~]$ host -6 lazer.aii-3.com
;; connection timed out; trying next origin
;; connection timed out; no servers could be reached
[rsas@lazer ~]$ host 10.20.18.140
;; connection timed out; no servers could be reached
[rsas@lazer ~]$ host -v -t a lazer.aii-3.com
Trying "lazer.aii-3.com"
;; connection timed out; trying next origin
Trying "lazer.aii-3.com.aii-3.com"
;; connection timed out; no servers could be reached
[rsas@lazer ~]$ dig +trace lazer.aii-3.com

; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.17.rc1.el6_4.4 <<>> +trace lazer.aii-3.com
;; global options: +cmd
;; connection timed out; no servers could be reached
[rsas@lazer ~]$ dig +noall +answer lazer.aii-3.com
;; connection timed out; no servers could be reached

I am not sure how to proceed. Any guidance/insight is deeply appreciated.
