So i have an existing network running off a single server running windows 2003 SBS. I am about to add a file server that originally was going to run Linux.. However.... i was wondering if i set up windows 2008 if i could add it as another domain controller? I just saw this: Adding a Server Running Windows Server 2008 to a Windows Small Business Server 2003 Network which seams to say i can... the goal of the 2nd server was to only be a file server... however, if i could use it as sort of a fault tolerance for the services running on the SBS machine (dns,wins, print server, sql, login server etc) then that would be cool as well. Thank you!

We have some 30 brand new dell computers with office 2007 OEM. All the outlook clients are using pop3 hosted service (google apps). Sometimes a user will open outlook and it will ask them to create a new profile. if i look in c:\documents and settings\username\local settings\application data\microsoft\outlook after i create the profile, the original .PST is still there.. so i need to copy the Outlook.pst to Outlook1.PST and reboot outlook. why would outlook create another profile if the pst and other files needed are still there in their correct profile directory? what would cause outlook to think it needs to create another profile? this has happened 4 times in some 3 months, 3 of the times being earlier today. our office had a power outage, but to my understanding the computers were not restarted.. and once again - the profile folders were in tact, and the outlook data files were in tact. Thanks guys!
