I just built three machines for a client that seem to have a network issue.
All machines are exactly the same specs except one, which acts as the server/workstation.
They are Intel i3-530, 2GB DDR3 (server has 4GB), 500GB HDD, Win7 Pro 32-bit, Gigabyte GA-H55M-D2H mainboard with gigabit LAN and onboard video (server has 512MB ATI)
They are networked with a LevelOne Gigabit switch.
They also have an existing HP workstation which is a Core 2 Duo with 2GB RAM running XP Pro.
They are running a program called Orion - Dealer Management Systems (www.sam.co.nz)
All the workstations have a mapped network drive to the server/workstation and the Orion program just runs an exe file on this mapped drive - i.e it is not installed at all on the workstations.
On the server/workstation and the XP Pro machine Orion runs great and switching between the modules inside the program is quick.
On the two win7 workstations Orion runs OK and most things work as expected except switching to one module (the workshop one) causes a delay of about 10-15 seconds before the screen comes up but switching back to the main menu is quick.
With task manager running there seems to be nothing going on while this delay is happening, no CPU activity or network usage.
If I copy the Orion software to either of these win7 workstations this delay is not there which is why I suspect a network issue.
Testing the network however shows that it is running great - file transfers between workstation and server transfer at around 100MB/s as they are connected at 1.0Gbps on the LAN.
The SAM / Orion guy was onsite today and he blames the computers (of cause)
Anyone have any ideas on what to try to fix this?
I have checked that the network card drivers are up to date and have gone through most of the settings, for the network cards, in Device Manager (Receive & Transmit buffers, jumbo frames etc)
Cheers
