Error HRESULT E_FAIL has been returned from a call to a COM component

I dont know what is going on with this "Error HRESULT E_FAIL has been returned from a call to a COM component.". Do you guys know what happened? My wcf service was running fine, but today I got this error. I searched on google but no answers could be found.

Thanks in advance

Might be related to this: Some sharepoint-blog

That is - change to

    <configuration>
        <system.web>
            <identity impersonate="true" />
        </system.web>
    </configuration>

in web.config might work. Inverstigate the other possible consequences of this though.

These are generic vs controls, anything/everything in my page is giving the same error. Even with a brand new site created in vs

E_FAIL is a generic unknown error. There is no more specific information.

Rather than searching for E_FAIL, I'd search for support more specific to some of the COM components you are using, specifically which one actually returned this error if you can find it out.
