Hi all, I have a strange problem with windows 7 in combination with server 2008 R2. Situation. 1] I copy a bunch of files to the server (UNC of mapped driver) with W7 (32 or 64 bits professional.) 2] I want to delete the files i've just copied (same issue with modification) it is extremely slow. Only 1 file per second sometimes even slower. When I perform the same actions with Vista or XP it is extremely fast. For vista I had to switch off Remote Differential Compression. I did this also for W7 but no improvement. Delete files with the W7 machine is also fast when copied to the server from the vista or xp machine. I've tried serveral new machines with W7 but all show the same problems. Any help is welcome, with kind regards Roland

Try Fred Langa's fix @ http://windowssecrets.com/2010/10/14/01: "<big>Easy steps to a significantly faster network </big> <small> </small> To start, if you're in a homegroup, exit it. (Need info? See MS's Help page , "Leave a homegroup.") Once every PC has left the homegroup, it no longer exists. Next, to disable HomeGroup and change encryption levels, open the Control Panel, select Network and Internet, then Network and Sharing Center. Once there, in the left-hand pane choose Change advanced sharing settings. It's a two-click fix, as shown in Figure 1. Figure 1. Two quick radio-button clicks are all it takes to restore classic networking speed to Windows 7. In the Home or Work section of the dialog box, scroll down to File Sharing Connections and click the radio button for Enable file sharing for devices that use 40- or 56-bit encryption. (Note: You need this setting anyway, if you want to share files between Win7 and an XP box. More on this to come.) Next, a bit further down under HomeGroup connections, select Use user accounts and passwords to connect to other computers. Save the changes, and you're done!"

Thanks for the tip. Unfortunately this is not the solution. I am a bit further now and I have determined that the problem can be resolved by disabling the on access scanner of Norman (running on the server). The problem can be reproduced at Norman Antivirus and they are trying to solve it.

Did you ever fixed the issue ? i have exactly the same issue with a win2008 R2 x64 server with shares to win 7 x64 clients. Norman does not have a solution for me, and is still looking into the problem. Since its a few moths later now, im getting a bit scared that there is no fix.

Sorry for the late reply... I'm still having the same problems. I am in contact with Norman about the issue. They finally managed to reproduce it (at least that is what they told me). They've encountered the same problem without the antivirus installed. A temporary solution is to shut down the Norman Zanda and the Norman On Access Scanner service. Of course the server is than not protected, but in our case that is not a big problem since it receives updates etc from another machine which scans all files. SP1 -> same problem stays I've talked to an engineer (they called me instead of I called the myself) on the phone this morning and he told me that it was raised to the highest priority since more people encounter the same problem lately. I'm running everyting on a hyper-v platform with 3 virtual servers (SBS2008 and two Server 2008 R2). If i have a solution i'll post it here
