First off, I'm quite new at configuring Windows Server. I was forced to set up a server for a family business. I have one computer running Server 2008 which is set up as a DC, File Server, VPN, and I think that's it. It's only used as a file server, vpn server, and a network license server. So if I left out any of the installed options, you might be able to figure it out.
Anyways.. when I start transferring files the speeds are respectable, given the server is an old computer. Transfers start at around 12-18 Megabytes per second. After a few minutes it will slowly go down until the speed is at 4-3 Megabytes per second. The amount will fluctuate a couple megs for the rest of the transfer.
I found this post, which states servers set up as both a Domain Controller and File Server will have a slow transfer rate in Server 2003. Can you guys verify that this is still true in server 2008 for me?
