Issues with HTTP and HTTPS after CU1 and CU2 update.

Configuration:

Server 2012 64 bit (AD, DNS, Fileservices,IIS)

Exchange 2013 with CU2

(2 users currently)

problem is when i go to www.domain.com the request returns a blank page. This started after CU1 update.www.domain.com/index.html resolves fine.

SSL cert in installed and was all running fine. I don't understand what could have gone wrong. when SSL was enabled browser returns 403.4 and rejects connection. Disabled SSL and it returns the blank page again.

Checked default docuent also, but still returns blank page.

Any help would be appriciated.
