I have a server I recently upgraded from 2003 64bit to 2008 64 bit
Its a barebone system with
Intel P35/G33/G31 Chipset
Phoenix Technologies Bios
Intel Core Duo E6750 Processor
4GB RAM
Single Gigabit NIC – Generic Marvel Yukon 88E8056 Based Ethernet Controller
I upgraded because I wanted to have better experience on 2008, to use the
Virtualisation and also because I share the server on a KMV with two other
machines and now use a wide screen display and there was no VGA driver that
worked with 2003 64 bit to support it (there was a Vista 64bit one and that
works fine)
I’m running AD on it as well as SQL Server 2005. Its primarily for testing
etc but I run real services from it so its in a semi live environment so we
can do real tests!
I did a clean install of 2008 Enterprise 64 bit and installed the core
drivers – actually only the VGA was needed as 2008 recognised everything
else. I ran all the MS upgrades and patches and added the roles of AD and
migrated the domain. (I used a second PC to temporarily transfer the AD roles
to then moved them back to the 2008 server. That all worked fine. I added DNS
and DHCP and configured all and it all worked. Everything seemed fine but I
didn’t really notice or test network speeds. I then added HyperV and noticed
after setting up a Virtual machine, that the DHCP didn’t work. I discovered
that HyperV can not use the same NIC as DHCP so I temporarily turned off the
DHCP. (I will add a second NIC once the other issues are resolved)
Apart from that all seemed fine. Then I discovered really slow network
transfers from the Server to the XP Workstations. I have no Vista PCs to test
on as we are all retaining XP so it needs to work with XP. From XP to Server
is fine. They are only on 100mbs so the throughput matches that. But file
transfers from the 2008 Server to the XP machines is very slow. Like slightly
under 10mbs. Or 30secs for a single 25MB file vs 3 secs the other way.
I have not added any AV tot he server yet. I hate Symantec Endpoint. Its
bloated rubbish and screwed up my 2003 server previously. Will probably put
Symantec Corporate on when all is sorted but behind great gateway AV so not a
huge problem at this stage. Nothing much else installed except core MS stuff
inc SQL 2005 and IIS 7 roles.
I tried killing none crucial services, reinstalling NIC drivers, disabling
the firewall. I removed the Virtual Lan from Hyper-V so its currently
offline. No change.
I read that Vista had issues that were fixed in SP1 but 2008 should have
those fixes already applied. I haven’t yet messed with the NIC driver
settings as there are a bunch and I really have no idea where to start there
but realistically I shouldn’t have to change them – or should I? I’ve run out
of things to try – still inbound is fast, outbound is slow. I had three IPs
on the NIC but tried removing all but one. I unchecked IP6 from the NIC
Bindings. No Change. Simple Gigabit switch. No Firewalls on internal subnet,
2008 Firewall disabled, no virtual LANs, no DHCP – only AD and DNS. Its
really really frustrating. I’m pretty clued up on this stuff and have played
with 2008 a fair bit now but this one has me temporarily stymied.
Any clues would really help. Nothing on Google searches has revealed
anything that helps. Would really appreciate some input here. Many thanks
