Set-up: Windows 2000 Server (PIII 800 / 1Gb ECC SDRAM) with 2 x 80Gb mirrored drives, running Terminal Services to eleven workstations running Win2000 Pro. Only two applications, both medical programs - one a clinical program currently based (I think) around MS Access and the other a appointment/billing program based on MSDE SQL. 10/100 network switch with CAT5 cabling. System has been in place for around three years and I believe there has been no defragging or changes in that time.
Network performance has been progressively getting slower and the program's help desk has said "Add more RAM" which I guess may be the answer but also appears an easy answer for them.
I guess there are a few questions here........
1/ Can RAID drives be defragged without too much difficulty/danger?
2/ If yes to 1/ then will the Windows defrag do the job initially, with a view to going to something like Diskeeper later on?
3/ Any other suggestions as to what may be making the network sluggish or on how to improve the performance?
