I have a Dell PowerEdge T110, Windows Server 2008 R2, Intel Xeon X3440 2.5 GHz 8 MB Cache, 16 GB 1333MHz,PERC S100, RAID1, 2 x 250GB 7.2K RPM SATA
We're running Quickbooks V12 and have up to 7 users connect to it using Remote Desktop. When there's one or two users connected to the server, it consistently hangs in Quickbooks, Word, Adobe Acrobat and pretty much everywhere. Physical memory usage doesn't seem to be a problem as it runs around 40% usage. I've scanned it for malware, viruses and rootkits but not a trace anywhere. I installed Defraggler because it has this little hard drive benchmark utility that I like to use to gauge the performance of a hard drive. It was running random read tests at 1.5 Mb/s which seemed a little slow to me. After a full defragment, it was running at 2.5 Mb/s, which still seems like it should be faster. I'm not sure what else to try or how to diagnose this issue. Please let me know if I've left out any information that might help. Do you have any suggestions or recommendations?
