Window SBS 2003

Hello Everybody,

I have a Windows SBS 2003, which is primarily used as a file server. Shared folders with plain ascii text files are accessed by users to read and write through a DOS 16 bit application. Users also use the shared folder to view "images" in the DOS application.

My challenge is

(a) The Page/Sec is peaking to 100% every 10 seconds and the result is erratic performance - delays experienced by user.

(b) The disk queue also peaks to 70-100% once in 10 seconds.

The server is a Dell PowerEdge 2800 with 4 GB RAM and a Raid 5 System. Approx 30-50 users connect to the Server at a time. The primary is a PDC for the domain. All possible services are stopped on this server and DNS, WINS etc is load balanced to a secondary server.

Any help to improve the performance of the server will be sincerely appreciated. Please let me know if I can offer any more stats to diagonize this further.

Did you say it is or is not the domain controller?

SBS should not be the domain controller if possible, and ideally, though it can handle up to 75 users, it functions best for a network of less than 30 nodes
