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?

Subject: [enterasys] DNS not resolving after the upgrade.
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.
