Great information from Bob Cerelli's windows page:
"1. Remove current shortcuts in My Network Places
2. Change the registry so shared folders on remote computers are not automatically added to My Network Places when you even open a document from that shared folder
Start Regedit
Create a DWORD value:
HKEY_Current_User \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer \ NoRecentDocsNetHood to 1.
I have also seen setting the following help as well.HKEY_Current_User \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer \ UseDesktopIniCache to 1.
Download Reg file to do both
3. Increase the amount of data is buffered at one time to send to a client. On the computer with the shared directory:
Start Regedit
Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
Create a DWORD Key called SizReqBuf
Give it a value of Hex FFFF
Download Reg file"
