HI,

We have LYNC 2010 in our environment and pool is created with 6 frontend servers. We are configuring LYNC Mobility however after proper configuration we are getting below error

"HTTP Error500.0-InternalServerErrorModule"OCSAuthHelperModule"could notbe found"

For above error what action we need to perform without uninstalling the webcomponent role as maximum links says to unsinstall the web component and install again. All other features  fine

Do we need to follow all the same steps for lync 2010  mobility on all 6 frontend servers or it is required only on one server?

Hi,

Did you deploy Reverse Proxy for the access of Lync mobile client?

If not, you need to deploy the Reverse Proxy in DMZ zone.

If you have deploy the Reverse Proxy, please try to uninstall the web component and install again for all 6 FE Servers, and then test the issue again.

Best Regards,

is there any other troubleshooting step instead of uninstalling the webcomponent role?
