I have a question. I just recently upgraded to win7, my girlfriend runs win vista and my old laptop has winXP. Guess which can copy files from my Duo fastest.... yes.,..you guested right, it is the old XP laptop. I am not saying that the ReadyNAS is not compatible with win7, because online is lot's of people who cannot run copying from NAS (any kind) with win7. I am just wondering if you guys had a chance to test win7 yet, or just play around with it, I am copying file 5MB for 30 minutes (if I am lucky and the OS won't hang), with XP....flawless...I am keeping asking myself these questions over and over again. Why they release OS with this, should I say bug? Win Vista on my girlfriend laptop is same all pain, cannot copy nothing from NAS, I wanted to install Office 2007 last night, and guess what, I had to restart me PC, because it just froze, I could not copy the files to my desktop. On the other hand, the laptop with XP on, starst copying and after 15-20 minutes is over. It is frustrating, I know you not Microsoft support, like I wrote in beginning, would like to know if you had chance to play around with win7 copy, and if yes, what is the NAS file copy performance.

There is no issue with win 7 and NAs boxes other than most NAS use older samba (LM)I use three different NAS boxes with our win 7 boxes without any issues at all.My "Media server" is a nas box which I stream FULL HD movies off of.

Really? What build is your copy of win7? Thanx Petr.

I have run the beta's and now run win 7 pro all using NAS boxes on the network.

Thank you, I start thinking that it might be my router....which is not in the hardware compatibility list. http://www.microsoft.com/windows/compatibility/windows-7/en-us/Default.aspx?type=Hardware

I just went thru this, a customer had purchased a new laptop and linksys router, the laptop sitting right next the router would buffer Hulu every 3 ~ 4 mins.a 4.7 gig movie took over an hour to copy, there was firmware update but it did no good, I disabled IP6 on laptop rebooted and all is good now.

I am sorry, what is exactly IP6? And how do I disable that? Thank you

Thank you, I will do that and test the speed.

If that does'nt work try taking a look and changing the following Hold Windows logo key and strike the "R" keytypesecpol.msc into the run dialog box Expand "Local Policies" and select "Security Options"Locate "Network Security: LAN Manager Authentication Level" in the list anddouble click Change the setting to "Send LM & NTLM - use NTLMv2 session if negotiated" Network Security: Minimum session security for NTLM SSP Based (including secure RPC) Clients Change the setting from "require 128 bit" to unchecked (No Minimum) Click OKSee if that helps

Just wondering if you have included office 2010 in the picture? I never had any issues until office 2010. It's strange, if I go to save to the NAS system from Word, Excel, etc. The other machines that connect to it see the file as garbage. usually some type of .tmp file is all they get. Any ideas?
