At the risk of being slapped on the wrist........ :-)
I set up a 2003 SBS a few years ago which was to be used by 4 users for file and print sharing only. Of course only having installed non-SBS O/S's at that point, I elected not to install all options. As I recall I did run the secondary part of the Installation with the desktop "continue installation" icon, however I un-selected most or all options, such as Exchange. I recently revisited this client, and now better understanding the need to install all components, and finding a few little items as a result do not function as expected, I would like to complete the proper installation. The "continue set up" desktop icon still exists. Thus my question: can I simply 'click the continue installation icon, 2-3 years later, and not anticipate any problems? This server has not had SP1, SBS SP1, etc., applied, and part of my concern is doing so without out properly completing the initial install.
Appreciate any input.
