Default Odd connectivity issue


I've been using Vista Business x64 for quite a while now and just
recently I added a new w2k3 server w/sp2 with Exchange 2007 sp1 to the
network. The new server is running VMWare with 2 MS VMs. The problem is
that when I start to use Outlook or connect to the server via UNC it's
unbearably slow. The ironic part is that I can connect to the VMs
without any problem whether I have VMWare using the primary LAN adapter
or not. If I am on the server I can UNC into my machine and move file
w/o any issue; it's only when my machine makes a request to the new
server. I can connect to other servers in the network w/o issue and
other servers can connect to the new machine w/o issue. Externally I can
use Outlook Anywhere and webmail. Actually, I have found that using
webmail internally is fine and really the only way that I can use email
all together. The systems are connected in the same subnet thru a nortel
3510 gigabit switch (I've tried turning off autonegotiation). If you
have any thoughts on what might be going on it would be very helpful!

Thanks!

Try turning off autotuning...

netsh int tcp set global autotuninglevel=disabled
and reboot...

This solves "most" of the problems when connecting to servers (mostly
Win2K3 R2 boxen...)
