Hello Juan,
Thanks for replying. Yes, I reviewed that thread prior to posting. The value of 'webdms.maxSessionTimeoutInHours' is set to the default of 240 on our site, which doesn't tally with the default timeout of 1 hour in SAS Studio. When change the Session time-out value in SAS Studio Preferences > Start Up, anything over 240 gives "This value is out of range". So I'm pretty confident the setting name is accurate.
As we onboard new server users we are now telling them to change the setting in SAS Studio, but not everyone reads our advice! It's turned out to be the biggest new-user annoyance. They like Batch Submit, but also want to go to lunch and leave an interactive session running. I've not yet suggested shorter lunch breaks
