Urgent: Cisco & Linksys DNS Issue

Cisco & Linksys DNS Issue


Due to a recent update regarding Internet domain name resolution, many offices using Linksys or Cisco routers are experiencing with ClearDent.
While we have a temporary fix, you will need to contact your network administrator or IT technician to permanently resolve the issue.

Reason:
The domain name on Cisco and Linksys router is set to CISCO by default. However ICANN (Internet Corporation for Assigned Names and Numbers) recently made CISCO a TLD (Top Level Domain), which cause a conflict to the original domain setting on your router and returns you the IP address 127.0.53.53 that means IP conflict.

Solution:
Temporary workaround:
Add the server IP in the host file on EACH workstation.
Host file is located at C:\Windows\System32\drivers\etc\host

Permanent solution:
Login to the router and change the domain name in router to OFFICEN82716720 or whatever unique name that's unlikely to be real in the future
Reboot Router
Type in command window with ipconfig /flushdns and ipconfig /registerdns on workstations and reboot.


The resulting high call volume is unfortunately delaying our support staff, but if you leave us a voicemail, we will return your call as soon as possible.
