[HowTo] Change control panel IP

[mayatoday]

I just did the following, no luck
joomla / other logins eventually fail with 500 errors now...
Rebooting server doesn't help either..

even ssh login takes 3-5 seconds for password line to show up ... initial user is quick but next step is really slow....

------- Update ---------

Possibly tied to resolv.conf...
Network denies all outbound dns requests at the firewall except for authorized internal dns servers...

after setting check for update to disabled and updating the name server list.
remove 127.0.0.1
update to another internal name server...
