I am currently upgrading my T500 laptops (2082-94U) to Windows7 and am having what I believe to be NIC driver issues. I loaded a fresh install of Win7 Enterprise x64 (tried standard and sp1) and now the data transfer rate when moving files on the network are extremely slow. They never get above 72k/s. This is happening on every 94U model that I try. I have an older T500 and also T510s which do not see the issue. I have tried the drivers (most recent and older versions) on both the Intel site as well as the Lenovo site with no luck. The transfer speed is fine if I load XP on the same systems.
Has anyone seen this and if so have you found a way to resolve? Thanks in advance for any help...

These are not on a HOMEGRPOUP but on a corporate domain. Odd thing is I have 4 models of Laptops and only one specific type of the T500 has the issue. Has to be a NIC version on that one specific model.
