Server 2008 R2 DNS

Here is the setup: 2 DCs for internal domain with AD integrated DNS all set to use root hints to resolve external URLs. Two of the DCs are 2008 R2 server core and one is Server 2008 full GUI. Recently the two server cores starting having issues. They will stop resolving .biz domain names, but the 2008 DC continues to resolve properly. Quick resolution is to restart the service on the server core boxes, but eventually those DNS/DCs will stop resolving .biz again. Ideas?

Hi dumamo,

There is known error with MaxCacheTTL:
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: 0x2A300 (172800 seconds in decimal, or 2 days)
