The Operations Manager Engineering Team has published a post on the #DNS Management Pack for #SystemCenterOperationsManager.
When viewing the Local Resolution Time monitor in the DNS#MP for Operations Manager, you may notice that the response time reported does not reflect your own real world results.
Two solutions exist:
1. Configure the DNS service so that it listens only on the IPv4 address. To do this select “Only the following IP addresses:” in the dialog above and choose only the IPv4 address from the list.
Note that disabling IPv6 at the OS level is not recommended as there is no way for us to predict how this may effect your environment. Also, if IPv6 is disabled on Windows Vista, Windows Server 2008 and later versions, some components will not function as expected. See Support for IPv6 in Windows Server 2008 R2 and Windows 7 for more information.
2. The preferred fix for this is to create a reverse lookup zone as well as the associated PTR records on the DNS.
One last note: You can run into the same issue If you don’t have a reverse look up zone for the IPv4 address of the DNS server as well. This is not isolated to IPv6 but rather is a function of the lack of a proper reverse lookup zone on the DNS.
