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.

Thanks.
