Hi Tshepo, I presuming IP addresses are allocated via DHCP. Can you confirm via ipconfig, on an effected machine, that it is receiving the correct IP addresses of the DNS Server?

Hi Sean; Confirmed all floors are using the same DNS server, Yes identical policies were applied to all the switches a week before the IOS update. Thank you Tshepo From: Sheil,Sean M [mailto:[email protected]] Sent: 24 February 2012 03:29 PM To: Enterasys Customer Mailing List Subject: RE: [enterasys] DNS not resolving after the upgrade. Tshepo, You might verify which DNS servers the client machines are pointing to. Also, is it possible that some policy has been applied to those ports? Sean --- Sean M.

Hi guys Will you please assist, I recently upgraded my C3 stacks ( 5 stacks ) to 06.42.10.0016 about 3 weeks ago. All has been working fine until the last 2 days when users on the 28th Floor and 30th floor could not resolve dns names. (they will access the sites when using IP address) The rest of the stacks 27, 29 and 31st floor users are working fine. One DNS server for all 5 Floors. No events logs have been recorded on the DC. I can not see any logs as the problem was happening. 28th Floor(su)->show switch Management Preconfig Plugged-in Switch Code Switch Status Model ID Model ID Status Version ------ ------------ ----------- ----------- --------------------- -------------- 1 Stack Member C3G124-48P C3G124-48P OK 06.42.10.0016 2 Mgmt Switch C3G124-48P C3G124-48P OK 06.42.10.0016 28th Floor(su)->show ver Model Serial # Versions -------------- ----------------- ------------------- C3G124-48P 10110925225N Hw:BCM56504 REV 19 Bp:01.00.52 Fw:06.42.10.0016 BuFw:06.42.03.0004 PoE:608_3 CPLD:2.0 C3G124-48P 10110918225N Hw:BCM56504 REV 19 Bp:01.00.52 Fw:06.42.10.0016 BuFw:06.42.03.0004 PoE:608_3 CPLD:2.0 Please advise if there are known bugs on this Firmware.
