As many of you may know, WSS Explorer View can be very flakey at times.
I have made several calls to Microsoft and below is a list of fixes they suggested to resolve the issues with Explorer View.
– Install IE6 SP1, if it’s already installed, make a repair
– Remove and Install the WebFolders (c:\winnt\system32\WebFldrs.msi)
– Install MDAC 2.8 SP1
– Register this key to support a url more than 100 caracters
– Install the patch Webfldrs-KB892211-ENU.exe
