1.  Open the web.config file in the NetCommunity directory.
By default, this will be in C:\Program Files\Blackbaud\NetCommunity

2.  Set the timeout setting to a larger value

<authentication mode="Forms">

<forms name=".ASPXAUTH" protection="All" timeout="60"/>


note: The timeout setting is measured in minutes; so to set the "remember me" option for one hour, set this to 60. To set it for 2 hours, choose 120, etc.
