Yes Sandeep,
All clients and server connect to a 1-GB network switch.
Small Business Server 2008 OS/ Dell PowerEdge 2900 64bit 24 GB RAM, OS resides on RAID 1, data resides on RAID 5.
The client in question is brand new, 64-bit Sony laptop, 8.0 GB RAM, 2.20 GHz Intel processor, and connects to the network via wired 1.0 GB/s connection speed. Runs Win 7 Pro.
I installed one other machine EXACTLY like this client on the same weekend, and it works fine, no prob. This one not as fast.
