Well it could be a DNS problem. You can disable DNS host name lookups by starting mysqld with the –skip-name-resolve option in the configuration file. Read here for more details: http://dev.mysql.com/doc/refman/5.0/en/host-cache.html
It is possible to override the compatibility mode in intranet. For IIS, just add the below code to the web.config. Worked for me with IE9. <system.webServer> <httpProtocol> <customHeaders> <clear /> <add name=”X-UA-Compatible” value=”IE=edge” /> </customHeaders> </httpProtocol> </system.webServer> Equivalent for Apache: Header set X-UA-Compatible: IE=Edge And for nginx: add_header “X-UA-Compatible” “IE=Edge”; And for express.js: res.set(‘X-UA-Compatible’, ‘IE=Edge’)
