Problemas al accesar a mi escritorio digital

Ayuda...
Este es el error que me esta arrojando el sharepoint:
An error occurred while accessing the dashboard. This
error may be caused by the proxy server settings for the
dashboard. Contact your server administrator. If you are a
server administrator, configure the proxy server settings
by using the proxycfg utility. Consult the product
documentation and the readme for more information about
configuring the proxy server settings. Important: You must
configure the proxy server settings for the dashboard even
if you are not using a proxy server. (1)
