Symptoms
Consider the following scenario:
-
You install the DNS Server role on a computer that is running Windows Server 2008 R2.
-
You configure the DNS server to connect to a public DNS server on the Internet for name resolution.
-
You do not configure any forwarders on the DNS server.
In this scenario, the DNS Server service does not resolve some external DNS names after it works for a while. Therefore, you cannot access some applications or some websites that rely on these external DNS names.
Notes
-
To resolve this issue, you have to restart the DNS Server service or clear the DNS cache.
-
This issue usually occurs if you use the DNS Cache Locking feature in Windows Server 2008 R2.
Cause
This issue occurs because the DNS Server service cannot correctly handle the situation in which the glue record is expired or removed.
