ERROR: Unable to connect to any of the specified MySQL hosts.

Hi all, 

I have run into an issue and not able to resolve it. 

There was a requirement to connecting to a MySQL data source. For that I unknowingly added an entry in the "ODBC Data Source Administrator" ->User DSN & System DSN 

I was totally unaware that I am breaking my SP setup (Development). Now Central Admin site and all other sites have stopped working. 

I tried repairing by re-running the config wizard but no use. Error I get is "An unexpected error has occurred." OR "Unable to connect to any of the specified MySQL hosts." 

But when I try accessing other site, its showing an error from the "machine.config" file: >

Line 284:    <siteMap>
Line 285:      <providers>
Line 286:        <add name="MySqlSiteMapProvider" type="MySql.Web.SiteMap.MySqlSiteMapProvider, MySql.Web, Version=6.9.6.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" connectionStringName="LocalMySqlServer" applicationName="/" />
Line 287:      </providers>
Line 288:    </siteMap>

Source File: C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\machine.config 

For record, I have already removed those entries from that User DSN & System DSN.Still error persists. 

If some has ANY IDEA how to resolve it... please help!
