Symantec Endpoint Protection MR2 to MR3 Upgrade

Not much to mention...it_just_works. THIS TIME.

Steps for upgrading:

1. Download MR3
2. Stop all SEPM services.
3. Run installer over the top of previous installation.

Interestingly, researching an Outlook error 0x800CCC0F while POP'ing email down from our mail host, I found this article about how much better MR3 will perform, even over the likes of v10.

Hopefully my test client will not experience any issues, as the SEPM surely didn't.
