I searched for the string (the message you got) and saw sites explaining what was the cause. Ignore this if you aren't technical. :) I also tried as you did, using my Windows 7, and got the same message. But, since you want to get in, I saw another link, and that worked. Then login top right. Replace the www with, or insert the prefix 'mb.' infront of the URL you stated. I got in. But you have to come back here and tell us if the web site owner mis-configured their machine/DNS mapping which lead to your error message. Deal? PS. the MBdot was in the resultant list of duckduckgo search engine. I'm a sucker at trying things. :)

Thanks cliff..... The MB. Is to access the message board directly. I have not got the same problems using google chrome. I'm on the board of directors of the association and will check with the IT guy tomorrow.
