Earlier tonight, I convinced myself I needed to install sp1 but when I went to the microsoft site it says sp1,sp1a-25MB express, and sp1a-125MB. I chose the big one, thinking the installer would give some choices but it gives hardly any, it just installs outright. I did choose to archive to C:\$NTServicePackUninstall$ during installation but those things can be unreliable, I might uninstall from the add/remove programs depending on what people reply. So far everything seems normal but the system info utility(msinfo32) is saying "failed" on outgoing e-mail,dhcp,and default gateway. Everything works though, I sent a test e-mail to hotmail. Thing is, what is the difference between sp1a express and sp1a ITT pro? What does it install and setup that should be turned off?
