When accessing one particular file server (FS06) from a new Dell Optiplex 980 Windows 7 64 bit computer, there is a 10-12 second lag on opening \\FS06 and each folder thereafter (even if you go back to a folder you’ve already opened). Accessing other servers on our network is instantaneous. FS06 and our other servers are in the same location. The network adapter is the onboard Intel 82578DM. FS06 is Server 2003 x64.
If you disable the network connection and then enable it (on the optiplex 980 Win7-x64), browsing shares on FS06 returns to “normal”, until you restart that is, then the problem returns.
If you install XP on the 980, it works fine.
All other computer models in our enterprise access FS06 without any problems.
The Optiplex 960 Win7-x64 had this problem, but it was solved by using an older driver version. XP did not have this problem on the 960 no matter what driver version.
I have tried every driver version available from Dell and Intel with no luck.
I tried adding a PCI network card (also Intel) and I had the same problem.
The Optiplex 980 is on the latest BIOS version.
I tried disabling the "Link Layer Topology Discovery" components of the local area connection, no change.
I've tried several 980's, this seems to be a problem with this model, its network driver, or Win 7.
Has anyone else run into this problem. At this point, this is delaying our Win 7 deployment. We have an unreliable work-around: powershell scripts that disable and enable the network connection in the AM, but it doesn't always run, (scheduling powershell scripts has been fun) and if the user restarts mid day, they run into this problem again. I'd love a real solution, but i'm thinking its a driver issue and I'm waiting on Dell/Intel to fix the problem...
