JSI Tip 7265. When you open a file on a shared folder of a remote computer, network performance over a WAN link is very slow?

When you open a file on a remote computer, Windows Explorer obtains detailed information about the file, and about the remote share. This process can take a long time over a slow link.

To resolve this issue:

1. Install the latest service pack for your operating system:

2. Copy / Paste the following to a WANSpeed.reg file:

"SuppressionPolicy"=dword:00100000

[HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerSCAPI]
"Flags"=dword:00100c02

3. Merge the WANSpeed.reg file with your registry, or run regedit /s WANSpeed.reg.
