What HIS services do you have running?

[psuprogrammer]

Hi all,
I'm trying to get a feel for what HIS most users have running. I'm not too familiar with HIS server, but need to become familiar with how users typically use the HIS services.

There are 5 services on my HIS install that are running by default:
SnaBase
SnaRpcSvc
SnaMngAgent
SnaHostAcctSync
SnaDDM
Do users ever stop any of these? Or are these all pretty much needed all the time? I also have some other services that are not running by default:
TN3270
TN5250
SnaServr
SnaPrint
SharedFoldersGateway
Are these ever started manually by the user? or just somehow automatically started by HIS when needed?

Any advice would be greatly appreciated.
Thanks, Dan
