Windows 2003 R2, sp2
broadcom card - onboard
I have an old server, I run a copy test (robocopy) and transfer rate is 500-900 MB/min
I build a new server, plug the same network cable into the new server, and the transfer rate is about 190 MB/min.
I have checked the duplex and speed are correct
I checked the mtu is correct
there are no errors or collisions on the switch (my network guys say all looks great)
I called the vendor (dell) and validated ALL the drivers are current
I added an Intel card with current drivers, still no change
I flashed the bios, BMC,DRAC, and SATA - no change
Re-checked the old system on the same network is still working
I am at a loss, I would suspect hardware, but the additional Intel should have bypassed the bad card. I have a heavy backup cycle in 7 days, and this is urgent, any help would be wonderful
Thank you advance!
