I have a Windows 2008R2 36GB RAM, Intel Xeon processor server which does a couple of strange things, the first is using either 64bit or 32 bit IE8 (makes no difference) the download speed of files, or from websites, or speedtests from speedtest.net either fail as they are too slow and timeout, or are just so slow it makes things unworkable. Local network traffic performs normally. The problem only manifests itself when downloading from the internet.
The second issue is from time to time I have had a problem with the static IP when it first went into production after a few days it would not retain the IP it was given, this m,ay have been a teaming issue. So I broke the team and applied a single static IP. It appeared to be stable for a while but it decided quite randomly today to revert back to its previous IP address!!
Its running Websense email security and an EDM application, McAfee AV software.
I have changed the quad port NIC with no change, changed UTP patch cable, connected the server direct to the router, still no difference in the test results!!
Have 2 other servers similar spec but much much faster download speed, I have compared settings and changed where different, still no better.
Any ideas would be great, thanks experts.
