I have no data to back this statement up but here goes: every IT has heard of LogMeIn.
I offer an alternative: GFI MAX. http://www.gfimax.com/remote-management
On the advice of himuraken I have been using MAX to support two Windows servers, one Windows desktop and (now in beta) a Debian server. I still have a ton to learn but the initial though it that this service is pretty solid. The main IT user interface is the dashboard which is very intuitive. Similar to LogMeIn Central, the monitored devices are split up in to client groupings. A big advantage of LMI is that all the cost is in the connected server/PC fee. There is no additional cost for the dashboard functionality.
Agent install is straight forward with multiple delivery options. You do have to configure the remote control separately from the monitoring agent.
Much more to come as I dig in to this service. Certainly interested in hearing from anyone that uses this.
I am still using this service and I am really enjoying the notification system. Alerting is very easy to configure and can be applied to groups of systems that have similar needs.
The Linux agent is now in general release. Looking forward to getting more clients set up (and paying!) for this tool in 2013.
