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:

How to Obtain the Latest Windows XP Service Pack.

How to Obtain the Latest Windows 2000 Service Pack.

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

REGEDIT4

\[HKEY_CLASSES_ROOT\*\shellex\PropertySheetHandlers\\{3EA48300-8CF6-101B-84FB-666CCB9BCD32\}\]
"SuppressionPolicy"=dword:00100000

\[HKEY_CLASSES_ROOT\*\shellex\PropertySheetHandlers\\{883373C3-BF89-11D1-BE35-080036B11A03\}\]
"SuppressionPolicy"=dword:00100000

\[HKEY_CLASSES_ROOT\*\shellex\PropertySheetHandlers\CryptoSignMenu\]
"SuppressionPolicy"=dword:00100000

\[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\SCAPI\]
"Flags"=dword:00100c02

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

4. Shutdown and restart your computer.
