We have 2 identical servers running 2003 Standard edition with Terminal Services. One is also acting as a Domain Controler. Both servers have a mirrored pair for each Logical Drive (C:\ on one mirror and D:\ on the other). Pagefile usage on both servers are the same, system managed on the D:\ drive with performance optimised for background services rather than Programs.
The problem we are having is the fact that the DC server is getting a drive read/write throughput of around 25 - 30 MB/s where the other server is getting throughput of about 270MB/s. This result is seen on all drives including External SCSI drives and even Pendrives. We get these readings using PerformanceTest V6.1.
We have swapped out the drives between the servers (DC drives into Terminal Server and vice versa). The problem followed the drives. So now DC drives in the Terminal Server chassis has the throughput slowdown, where the Terminal Server drives in the DC chassis are getting the high throughput.
I am attaching a HijackThis log file for a little more insight into the slow performing DC
Thank you in advance for your help on this issue.
