I am running Windows 7 Beta Build 7000 on my desktop, and Vista Ultimate on my laptop. I have them connected through a router in a wired home network. Both machines have static IP addresses assigned. Here's my problem: When I try to transfer a large file (1, 2 or more GB) from the laptop to my desktop, initiated from the desktop, the transfer begins. But, after a while, there is a short interruption in the transfer. I see this as a sudden drop of the transfer rate on the network monitor. The transfer then begins again from the start. Again another short interruption. After a few occurrences like this, I get an error message on my desktop saying the the file cannot be found. Hoping that someone can shed some light on this. Thank you!

Try this: go to run...type gpedit.mscselect Windows Settings under Computer Configurationselect Security Settingsselect Local Policiesselect Security Optionsgo to > Microsoft network client: Send unencrypted password to third-party SMB servers...set it to ENABLED

hi, josechu. thank you for your help. since i posted my original post, i installed windows 7 on my laptop also. this seemed to take care of the problem. nonetheless, i went ahead and followed your instructions on both machines. i was wondering if you could give me a short description of what this setting does, and the associated implications.i also did a couple of more things per suggestion from a different post as follows:1. removed MMCSS value from the DependOnService key in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Audiosrv2. disabled the Multimedia Class Scheduler service.wonder if you could tell me if this would have a beneficial/detrimental effect on my network, especially when streaming multimedia.thank you!
