version of SP

Hi,

How can I determine which version of service pack, that I have installed on my Microsoft Exchange Server. I want to make plans to install the next service pack available, mainly because we have been experience server related errors on the network.

Not only am I a newbie, under 3 years, but I have only been at my current location, less than a year and was not around with the set up of the server.

Thanks
Shawn Miller
