Odd connectivity issue

I've been using Vista Business x64 for quite a while now and jus
recently I added a new w2k3 server w/sp2 with Exchange 2007 sp1 to th
network. The new server is running VMWare with 2 MS VMs. The problem i
that when I start to use Outlook or connect to the server via UNC it'
unbearably slow. The ironic part is that I can connect to the VM
without any problem whether I have VMWare using the primary LAN adapte
or not. If I am on the server I can UNC into my machine and move fil
w/o any issue; it's only when my machine makes a request to the ne
server. I can connect to other servers in the network w/o issue an
other servers can connect to the new machine w/o issue. Externally I ca
use Outlook Anywhere and webmail. Actually, I have found that usin
webmail internally is fine and really the only way that I can use emai
all together. The systems are connected in the same subnet thru a norte
3510 gigabit switch (I've tried turning off autonegotiation). If yo
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...)
