This worked for me: XP Pro – Vista Home Premium slow file transfer. Read all the blogs, tried many “fixes”, then saw yours on disabling firewall. Searched and found MS Security Essentials running and disabled it. Voilá! Back to decent transfer / back-up speeds on network (300mb in 4 min. rather than 153 min.)Nothing to write home about but definitely an improvement . Having a business network, I’ve steered clear of Vista for years for this and other reasons. Moving soon to Win7 and hope for the best. Certainly won’t expect too much help from MS.

Woot, I figured out the duplex stuff, theres a lot more stuff in my ethernet config then on the XP comp. Got it to run at 5.3mbs/sec atm, and it’s going up slowly. There was one problem, my Vista computer kept going going offline at the moment I switched duplex, finally stayed online at 100/Full, so I switched the other computer to that and it seemed to work, anyone got a quick answer for this? Thanks for the help btw, I figured I should be transferring faster than I can download, when I looked it up I was surprised I was only transferring at 1/15th the speed I should be.

Also, I did the steps above, still doesn’t work.

Ok, I have Win Vista, SP1. I don’t know much about networking, but I see you guys whining that you get 3/4 MBs, I get 6 or 7 kbs tranfer rate lol. I don’t know whats up, disabled Norton/everything. There are 6 computers in the network, and I have an old switch setup, the problem I have it only with this computer, and it happens to be the only one with vista. Believe, when I say I don’t know much, I’m not kidding. It took me like 6 hours to get all the computers on the same visible network. And another 3 hours for one of them to have internet.

I don’t know what you guys mean when you say half full duplex, please elaborate on this.

seems to be the same issue with windows 7 as well. Did you guys change anything on the server-side? I think it’s odd that I can quickly connect to this one server but not another.

[...] 1 for Vista, and disabling a few unnecessary services that slow down network transfer speeds (see this guide). After all that, I now have a decent, centralised place to store all my data. The only [...]

Well, turning off switching to half duplex worked for me on my win 7 machine with Nvidia eth. adapter.

I just want to tell you that your blog is very interesting, bookmarked
