Enabling Wildcard Domain Causes Clients to Receive Zero TTL and DNS Resolution Failures on Windows  #241

Issue Description:
When enabling wildcard domains, DNS clients on Windows intermittently receive a TTL of 0 seconds for the resolved records. This behavior causes DNS resolution failures lasting 10 to 30 seconds. Interestingly, this issue does not occur on Linux systems.



Related Issue:
A similar problem was discussed in hickory-dns issue #1849.

Proposed Solution:
The problem appears to be resolved by merging PR #1850. Although Trust-DNS v0.23.0 includes the fix from this PR, the project author does not use dns-over-openssl, which leads to build issues for zeronsd.

My Solution:

  1. Created a new forked project to merge the above PR:
    Forked repository with fix.
  2. Updated zeronsd to reference the forked Trust-DNS implementation:
    Commit in zeronsd.

Results:
After applying the fix, DNS resolution on Windows no longer encounters Failures, and clients receive valid TTL values.



Request:
Please merge PR #1850 to address this issue.
