You do not want to block 135 for:

. your local LAN subnet
. your exchange server

Open it back up but permit it through the firewall in these two cases. There are other ports you should allow on your private LAN and your Exchange connection:

You may be using a different firewall, but permit these ports as described in the KB article.

You might consider a proxy server such as the Microsoft IAS server.
