We are running into an issue with Sharepoint Portal Server. We are
having issues connecting to a document library when using Explorer
View. The problem appears to occur on Windows XP machines with SP2
however we have also determined it may have something to do with a
Hotfix (http://support.microsoft.com/kb/902395) applied to machines
still using XP SP1. The work around is to make a registry change to
the client and to enable WebDav in IIS.
This issue is documented at Microsoft support in the following url.
http://support.microsoft.com/?kbid=841215
We currently have two applications running one on port 80 and one
running on port 8081. These errors only occur on the application
running on 8081.
We have tried enabling WebDav as a work around but when flipping
between the two applications we are running into other issues with
WebDav enabled, plus WebDav enabled seems to be a security risk based
on further readings. One issue was a user got a blue screen error.
Upon looking at the core dump we searched and found info on the XP
WebDav redirector file called "mrxdav.sys". This led us to a couple of
KB articles. One (http://support.microsoft.com/?kbid=832143)
specifically addressed the blue screen problem. The other
(http://greenbytes.de/tech/webdav/webdav-redirector-list.html) seems to
better explain our different problems with the "Explorer View". It
seems that many of the redirector versions have issues with basic
authentication and most interesting, explicit port setting in the URL.
Have you heard of any of these issues before? Is there more info you
can give us on how to resolve it. The explorer view is used quite
often when loading content onto the site. Thanks.
