Essentially what happens is when the DNS server saves the NS record the TTL (Time To Live) for the A record is changed to be 1 day, But  TTL for the NS Record stays at 2 days. When the A record expires the DNS server starts returning SERVFAIL therefore it wont display the website.

Workarounds include restarting DNS, clearing the DNS cache, using DNS forwarders instead of root hints and setting maxcachettl to 2 days or greater, i wanted root hints to work correctly to stop ant problems with the isp DNS servers affecting our internet so i altered the maxcachettl settings.

1.    Start Registry Editor (regedit.exe).

2.    Locate the following registry key:

3.    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters

4.    On the Edit menu, click New, click DWORD (32-bit) Value, and then add the following value:

  • Value: MaxCacheTTL
  • Data Type: DWORD
  • Data value: 0×2A300 (172800 seconds in decimal, or 2 days)

5.    Click OK.

6.    Quit Registry Editor.

7.    Restart the DNS Server service.
