Can someone elaborate on these 2 choices\n\nI will be installing Win2k3 for use as a webserver to host multiple websites (home office-type setup). I was planning on buying the 10CAL standard edition. I take it that with the 10CAL edition, a max of ten "authenticated" users can be logged on to the server at one time. But anonymous users have no bearing on the CAL count. That right? If the 11th user attempts to logon, Win2k3 informs them about max users? What controls the timeouts that freeup the seats? Keepalive settings\n\nReading [URL]http://www.microsoft.com/resources/sam/lic_cal_win2003_server.mspx[/URL], per server sounds like the choice.
