Hi,

We're Planning for an Enterprise ISP and reached to point to decide about "which service on which OS".

I've talked with many people ; some bashed Linux, some bashed Windows 2000.

What I need is first of all, do you suggest a full-linux-based or full-windows2000-based or an integrated solution?

The services that I need to have on these OSs are :

AAA (Authentication, Authorization, Accounting) (+Centralized Authentication)
DNS (internal and external)
DHCP
Web Server
Mail Server
Firewall
Cache

The factors that are important for me are Availabality, Reliability and Security. as you know, Uptime for an ISP is very important.

If you suggest an integrated solution using some services on linux and some services on windows, would you please tell me which-on-which and why?

The only reasonalbe difference that I know is Linux does not need restart on most new patches. (Uptime)

Also I need "Switch Fault Tolerance" (NIC Teaming) which as far as I know, Intel NICs only support this on Windows.


Regards,
Joe.

I can answer a few of those.

Firewall-neither.  Get a hardware based firewall.  There much faster.  If you have to reboot, they are usually working in under 30sec.  No OS vulnerabilities.  Get cisco or sonicwall.
Web server.  Both, customers writing there own site may need either (front page, etc)
DNS/DHCP-for internal, if you have win2k clients, windows because of active directory, dynamic dns and registration.
External, hey what can I say, Im a microsoft guy.
Email-exchange will cost you a fortune for each mailbox.
The intel teaming works great, and I also believe its windows only
Linux does not need a reboot as much, however .net 2003 due in about 6weeks wont need to reboot much at all.  Also, IIS6 in 2003 is much improved over iis5 in 2000.  The other benefit for you may be the clustering support in 2003.
