Internal DNS Error

My lab is experience odd DNS errors. The internet address http://bis.ldsbc.edu (172.16.1.11 internal IP) is not resolving correctly. Some computer gets the correct webserver but others get a second server that has an internal ip address of 172.16.1.12.

The records in the internal DNS server seem correct. I am working the issue.


 

Gathering Information

I need to identify which computer had the issue with DNS. I only remember workstation 43 having an issue. I will ask students to give me feedback.

The error continues to happen. Server1 and Server2 are still being resolved to bis.ldsbc.edu.


 

Hypothesis

H1. Create an A record for bis 172.16.1.11 and the situations should be fixed.


 

Results

Still have issues after H1 was completed.
