We have DNS sever cofigured on Win 2003 The DNS was working well till last evening. The LAN users uses this DNS server for internet access. Suddenly we face problem with internet access in LAN. Once we restart the DNS services the internet works fine for some period. We need to restart periodically when ever we face this issue. Any idea what could be the Problem? The event log for DNS doesn’t have any error.. Pls advise any trouble shooting methord.
