Symantec Mail Security for Exchange

Hi-

We are looking at installing Symantec Mail Security for Exchange into our environment, however, our environment for our Exchange server is clustered with a DAG.. We also have an Exchange server in our DR site.

I attempted to install this earlier and it kept hanging on one of the services not letting Exchange use it.  I also had a permissions issue to the server, I kept receiving the message, "the user (administrator) does not have sufficient rights to the server".  I added this user to every group that was mentioned.

What is the best way to implement the mail security for exchange in this environment?

Please let me know if you have any questions.

Thank you,
Peggy
