Odd DNS Timeout Issues

hello everyone.

i've been having long term issues microsoft dns server on 08 server box runs in house's basement. server manages active directory , hosts sql server among other things. client computers in house use server primary , dns server. dns role on server has been left in vanilla state, no forwarders etc. 

this works fine, generally. local lan dns lookups work fine time. however, internet dns ups more sporadic. majority of time internet looks ups work fine , there's no issues. (every couple of days) addresses, resolved fine time out when client tries contact dns server.  right-clicking in dns mmc , hitting "clear cache" solves issue , address resolves fine. 

i've tried research on issue, without tangible success.

i'd be grateful if able me this. 

hey yman,

googled 'server 2008 dns timeout' , found here.
i'm having similar issue, yet sort it.

1 thing note, found warning in dns event log event number 4013 might give clues.

don't have further @ moment, thought might benefit you.

cheers.
