Extremely slow network file copy in Windows 7 from 2008 Std svr, but works fine in Safe Mode??
I have searched the internet and have tried just about every fix I can find and can't fix this problem. I have (3) exact IBM Lenovo Y510 notebook workstations that had fresh installs of Windows 7 Pro 32bit that are having extremely slow file transfer speeds between the workstation and the 2008 Std 32bit, SP2 server shares. Normal copy speeds appear to be 10-12mb, but these notebooks start out high, then quckly diminish to well under 1mb in less than a few seconds. However, when I boot the workstations into safe mode with network, they work just fine.
These notebooks have Broadcom NetLink BCM5906M PCI-E Fast Ethernet Controller cards on them, and have been updated with the latest drivers from broadcoms site.
Network: SonicWALL TX210W, with latest firmware
Dell PowerConnect 2824 24 port Gigabit switch
Other IBM Lenovo model notebook and other work stations work fine
It works in Safe Mode, but thought I would post netsh interface show config so noone would post that:
C:\Users\Katrina>netsh interface tcp show global
Querying active state...
TCP Global Parameters
--------------------------
Receive-Side Scaling State : disabled
Chimney Offload State : disabled
NetDMA State : enabled
Direct Cache Acess (DCA) : disabled
Receive Window Auto-Tuning Level : disabled
Add-On Congestion Control Provider : none
ECN Capability : disabled
RFC 1323 Timestamps : disabled
And I have tried everything here 1 at a time:

I'm really needing to get this fixed right? So I reactivate my Technet Plus Subscription so I can use one of my Incidents and they said afterwards it takes about 3-4 days to get it ready for use again. So, after looking back on EE again for a while, thought I would send out a request for help.
Thx so much for any input! - Billy :)

from my personal experience, it was the QoS layer in the network setup that caused the speed issues. When disabled, it was OK.
when in safe mode, there isn't a service that is being loaded...if disabling QoS won't help, not sure what it could be as I haven't had that problem on W7

Thx for the quick responses! Forgot to mention I had un-installed the AV. Will look at the QOS setting tomorrow...

I tried both disabling the QOS layer on the network card properties, and then disabling the SMB as was mentioned, and it did not work.
Any other ideas?
Thx ahead of time...

question...when the laptops are connected, are they connected to both the wired and wireless networks at the same time? or, are you testing them connected exclusively to one or the other?
try this: on your sonicwall under security services then under the first sub-tab. There is a drop-down box for security settings. Change this to optimized for performance. I've noticed double WAN speeds by doing this. Took me a lot of troubleshooting with sonicwall to find this.
What is going on is that with increased security comes the more signatures packets are verified against. By changing to performance mode it only checks high severity signatures (which is fine with us).

which security service are you referring to?

no worries...an awfully awkward situation to be in, sorry. recently, i had a situation where my laptop users were leaving the wireless enabled and docking their laptops. of course, the docking stations were connected the wired network. with the wireless and wired networks connect at the same time, file access was very slow. i updated the sonicwall firmware and that resolved it. of course, this was on a Pro 3060.
anyway, i'm a consultant as well, so i feel your pain.

As stated above, I am considering this closed w/o solution because I will not be able to try to implement any fixes due to the workaround.
Have you tried copying after disabling the real-time or on-access scanning?
