IE/Explorer apps hang midstream

[EdB]

Windows 2000 Server, SP4, fully patched (via automatic updates & Safe
Mode)

Suddenly, various IE/Explorer apps will not completely load; they
startup but hang in mid-load.
EX:
1) Start | Search | Files or Folders -- the Search screen loads, but
the hourglass remains, and the cursor does not appear/I cannot click
in any fields to type
2) Starting IE -- the browser loads, but then hangs upon "Web site
found..."
3) Windows Explorer - loads and the directory tree appears in the
left-hand pane; but when I try to expand or double-click into a
directory, it does nothing

All of these work fine in Safe Mode. I also did a full virus scan in
Safe Mode and real mode, but there is nothing. I also run SpyBot and
Ad-aware and removed the few tracking cookies it found.

I updated the video and network drivers; I also downloaded and
installed the latest IE6 from Microsoft (via Firefox, which installed
and works fine). Checked the Run... registry entries and found nothing
that shouldn't be there.

Suggestions? Am I heading for a re-install of the server?

Thanks,

FIXED!

It was the APC PowerChute software referred to in a similar thread:

You haven't by any chance PowerChute 6.x UPS software (APC) installed
on the computer?

If so, upgrade it to v7 or uninstall it and see if that helps.

PowerChute 6.x cases a lot of issues, much more than what is described
here:

PowerChute Business Edition - Customers Using 6.x Must Upgrade to 7.x
due to Java Runtime Environment expiration

This is how you can disable the PowerChute service if you are unable to
uninstall it:

Start Regedit.exe

Locate the key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\APCPBESERVER
Set the "Start" value to 4 (means disabled)
