Just found this registry hack to eliminate that annoying delay when browsing shared folders on Win98 from Win2k:
Step 1. In Windows 2000, click Start, Run, type
regedt32, and click OK.
Step 2. In the Registry Editor, navigate to the
following branch:
HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/Current
Version/Explorer/RemoteComputer/NameSpace.
Step 3. Under that branch, select the key
{D6277990-4C6A-11CF-8D87-00AA0060F5BF}. This key
instructs Windows Explorer to search for Scheduled
Tasks. If you wish, pull down the Registry menu and
click Save Key to back up this value. Name the output
file, say, Scheduled.reg, and you can easily restore
the key if necessary.
Step 4. Delete the key and close the Registry Editor.
This change takes effect immediately and doesn't
require a reboot, so you can determine how much it
speeds up the process.
