First off a little background on our network. I've inherited this network for Department, and it was poorly managed (found software with keygen etc- which I have removed) and not upgrade we currently have 4 windows 2000 Server (1 at each building)
I don't know if these issues have been happening at our other locations I assume it has. (as I'm not physically there much) but I'm located in the building with our primary DC.
We can get to websites and browse just fine. but on windows 7 clients you can't download any files (say even a 6mb file will take 6hrs + and we have a pretty good fiber connection). To get it to work on windows 7 clients I have to run this fix via the command line
"netsh interface tcp set global autotuninglevel=disabled"
after doing that they can download files fine. However It just doesn't seem 100% "right" to me if that makes since. sometimes finding a web page will take a while, not actually loading the page which is fast but it seems like there is some dns issues somewhere but I'm not sure how to pin point it.
and a big issue for us is with mobile devices - Our Ipads, android tablets, iphones, android phones, sony ereaders etc.
They can all load a webpage just fine (just like my win7 clients did) but they can't download anything such as an application update.
I've tried it with both a wireless AP only plugged into our Layer 2 switches and with a SOHO wifi router just to see and they both have the same result.
I'm not sure if the problem lies with in our Windows 2000 server or a configuration problem with our Cisco Router. I can't look into the configuration on the Cisco router as it's owned/managed by our ISP and they don't like us to touch.
This issue has stumped me. Any help would be appreciated.
Thanks
