Hi,
Not that I love Microsoft or anything, I feel I should write on a couple of points the True Texan made.
Windows NT (and 2000 and XP) were also built from the groubd up to be multitasking operating systems. In fact they were modelled on an operating system called VMS which in my opinion is still the best OS around.
I think what the TT meant to say was that Unix was built to be a MULTIUSER system. WinNT wasn't really although it doesn't do a bad job.
Yes, the True Texan is right about Microsoft's vulnerability to attacks. Although I dont believe that its much to do with the software - rather than the desire for people to kick Microsoft.
One thing about using the Internet Information Server is its integration. You dont get anything like as strong integration with thge other web servers. Many will "do the job", but not as well as the fully integrated Microsoft products.
Thats what Microsoft are really good at - integration.
re: Stability. Windows2000 is pretty stable now. Mostly stability problems are to do with configurations whether you're on Unix or Windows and a skilled administrator will be able to keep either running close to 24x7.
Unfortunately a lot of people bag Microsoft because they simply dont understand these configuration issues and they just want it to work without having to do any themselves!
Your boss has made his choice and its a fair one.
Cheers,
Tim.
