Windows 7 mapped drive latency with slow green progress bar and red X
First and foremost: We did NOT have these issues with Windows XP, and still run over 60 XP machines that have NONE of these problems.
We are having ongoing problems with Windows 7 and mapped drive latency on our network. Our environment is as follows:
Multiple servers running Windows 2008 & 2008 R2, some VMware servers (including our file server).
Windows 7 x64 came preloaded on a brand new Lenovo thinkpad, 4gb memory. This occurs on 4 different laptops. This problem ALSO occurs in exactly the same way on an HP Compaq x64 desktop running Windows 7 32. All systems are fully patched & up to date on SP's.
Running IP 4 & 6 on all servers & Win7 machines
Connected to GB Cisco switch
We run login scripts via GPOs that map drives (with net use commands) to 3 shares on our fileserver, drives G, H and S. A fourth mapped drive to an IBM Iseries does NOT experience these issues.
In Windows Explorer, mapped drives may or may not appear with red X's, but when clicked on they hang with a spinner and the green bar at the top of Explorer begins to run. This occurs randomly, but usually not right after boot up. It can take over a minute to complete. Also, in Word, which has references to these drives in file locations, file opening and saves can be very slow as it attempts to access these shares.
This issue has delayed our roll out of Windows 7. Its unacceptably slow and cannot be used in a production environment.
We have tried every suggestion we can find on the Internet:
Turned off autotuning, indexing, thumbnails, set autodisconnect to the max (both 99999 and ffffffff). Server & clients. No luck.
Changed properties on the mapped drives to optimize for documents...no change.
Changes setting on the network cards to disable flow control, set static link speed & duplex. Network drivers have been updated. Even tried using our wireless network and disabling wired connection...no change.
All bios and hardware updates are completed...no change.
Turned on and off network discovery..no change.
Disabled SMB2 on servers & clients...no change.
Disabled firewalls, and unloaded antivirus (Trend)...no change.
Safe boot with networking & clean boot with no services other than Microsoft...no change.
There has GOT to be a solution to this problems or Windows 7 is dead in the water for us. I have 10 laptops in boxes that we can't roll out. Please post ANY ideas!!
