Exactly the same problem here. Can click on save and excel 2007 takes 35 seconds to save even if I haven't made changes.
Same network as you.. 2k3 server R2 with XP Pro and Vista Business clients. Xp Machines save without problems or delays but the Vista machines all have the same slow save issue.
I have tried many possible fixes including the supposed hotfix, however the hotfix does not cover this issue. At least it did nothing for me.
1 possible fix is this one taken from another forum?
?I configed Windows Firewall with Advanced Security. Opened outbound rules allow all. Goto control Panel, swith to Classic View,click on Administrator tools,go into Local Security Policy, and there you will see firewall folder. Setup the profile your using with a new outbond rule. I had my fire wall off the whole time and still do, but this worked. I hope it works for you. Windows Vista has outbond rules in it's firewall unlike XP only having inbond. Silly me to think that when I shut off the fire wall that everything would be wide open. Aparently This has to be manualy set regardless. My transfer rate went from AVG 2.5MB to 72.3MB over Gigbit.?
Another possible fix from another forum:
?Slow Network Issues
Microsoft Windows Vista comes with a new network stack that can adjust or tune itself. On some machines rather than help file transfer speeds it actually slows it down. Many times this issue is caused by third party network drivers.
Auto tuning can also slow down network browsing of other machines on your network. If you are having local network slowness or file transfer problems try the command below to turn off autotuning.
You can turn on and off autotuning with a simple command line instruction.
Run the command at a command prompt (cmd.exe), you may need to run the cmd.exe as an administrator (right click "run as administrator"). Command Prompt by default is located under the Accessories menu folder. If you are logged in as administrator you can simple click "start" then "run" type in: cmd.exe and then run it.
To turn off AutoTuning
netsh interface tcp set global autotuninglevel=off
To turn on AutoTuning
netsh interface tcp set global autotuninglevel=off?
