When I copy a file from the workstation to the server (uploading from the WS) the data transfer is very slow, not more than 1MB/s
Also, when I do the same operation but downloading the files from the server, the data transfer is a little bit faster, but not more than 2MB/s
But when I transfer a file from the server to the workstation (uploading or downloading from the server) the data transfer is ok, about 10MB/s
I think this issue is also messing with the print service, because its also very slow.
Some info about the server:
- HP Proliant ML150 G6
- 100Mbps network
- Roles and services: AD-DC, DNS, AD-RMS, Exchange 2007 SP3, SQL 2008 R2, print and file server.
I've disabled the firewall, updated drivers, firmwares, BIOS. I've turned off IPv6, I've tried the following netsh commands that I found on Google.
netsh int tcp set global rss=disable netsh int tcp set global autotuninglevel=disable netsh int tcp set global chimney=disable
I've tried all those and reversed the changes because nothing worked.
I just installed the server 1 week ago, I remember that this problem was not bothering after installing AD-DC but before installing the exchange server 2K7... i dont remember after the E2k7 installation
After the E2k7 installation, I installed the AD-RMS role, thats when I realise the slowness of the system, and after installing the AD-RMS, I installed the SQL... so i guess the SQL isn't causing the problem.
I have had not the chance of test the transfer speed connecting the server and a WS directly, but I guess its gonna be the same slowness.
