We seem to be getting errors in DDM saying significant certain domains are not responding, such as hotmail.com and yahoo.com. I suspect the hosting server is having DNS issues. I have always thought that Domino relies on the hosting server to resolve DNS names but wanted to confirm this before I go back to our O/S guys to ask them to look again.
Are there any troubleshooting articles or advice that you can refer me to that may assist in DNS issues?
