Very slow network connection to 64 bit server

I am running Windows Vista on my laptop and use it to remotely administer the servers. I have recently got a new server installed which is running on Windows Server 2003 64 bit. At that time I checked that the remote desktop connection to this 64 bit server was very slow as to be unusable, (the connections to the 32 bit servers was fine), but even browsing the shares or transfering simple files is very slow too. Applications using data stores on the new server are unusable as well. All XP workstations and the 2003 32 bit servers can connect, share and transfer files normally with the 64 bit server. I think that it is a Vista problem, can anybody gimme some ideas? Thanks

You can try to go to Start >> Programs\Accessories and then right click on Command Prompt, select "Run as Administrator" to open a command prompt. After that type in the below text:

• Reset WINSOCK entries to installation defaults: netsh winsock reset catalog
• Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log
• Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log
• Reboot the machine.

I have exactly the same problems which are mentioned i wanted to know you found a solution for this problem ? Please inform me. Thank you very much in advance.

Here is what you need to do if you have the same issue:

- Run a command prompt (cmd.exe) as an Administrator
- Type: netsh interface tcp set global autotuninglevel=disabled
