Hi all, I've got a Server 2008 Foundation Edition server that's running some financial software. I have a script running a backup to a different (linux) server via WebDAV as that is the only server share that's backed-up offsite. The script was successfully mounting the webdav drive for a month or two and the backups suddenly stopped working last week. The linux server had been rebuilt, but everyone else using the webdav drive (win, lin, osx) all report zero problems after the rebuild. The original working command was net use w: http://www.XXXXX.net/webdav PASSWORD /user:vacri running that manually now just gives me an 'error 67 - network name not found'. What's confusing is that the same site with the same credentials can be successfully viewed in IE on the same machine, and the base domain can be pinged. I've also tried 'net use * \\www.XXXXX.net\webdav' and the error changes to 'error 53 - network path not found' list of things I've tried so far: net use * http://www.XXXXX.net/webdav PASSWORD /user:vacri (fails w/67) net use * http://www.XXXXX.net/ PASSWORD /user:vacri (fails w/67) net use w: http://www.XXXXX.net/ PASSWORD /user:vacri (fails w/67) net use w: "http://www.XXXXX.net/webdav" PASSWORD /user:vacri (fails w/67) net use w: http://192.168.1.10/webdav PASSWORD /user:vacri (this webdav also does not resolve in IE8) net use * \\edmund\share PASSWORD /user:vacri (works on a different computer's share) net use w: \\edmund\share PASSWORD /user:vacri (works) (all above done with administrator-enabled CMD) http://www.XXXXX.net/webdav * pings from the same command prompt * can be seen in IE8 with the above user:pass settings and tasks tried * sfc /scannow - ended with no faults found * chkdsk c: - ended with no faults found * Nothing in the Application or System logs that looks suspicious * Reverted policies that were changed around Remote Desktop timeouts (this was what I was doing the next day when I found the backups had failed) * Trying to map a new drive using the menu option in Explorer fails with the same 'Network name cannot be found' error * Changing secpol Lan Manager Authentication Level to any level has no effect * Changing registry key \HKLM\System\CurrentControlSet\Services\WebClient\Parameters\BasicAuthLevel to 0, 1 or 2 has no effect (was previously on 1, needed to do this to get webdav working in the first place) * Trying the net use command on an XP VM gives a different error (error 5, access denied) even though the same user:pass on the same machine allows access via firefox * Changing the network adaptor from 'public' network settings (high privacy) to 'work' network (allows more trusted connections) * The recent changes that have been hitting XXXXX have involved no reconfiguration issues around webdav * Network Discovery enabled, previously disabled My only way to get off-site backups is on this webdav drive and I can access it fine through IE8 - why not through the previously working method? Desperate for any hints. Or anything more solid than a hint.

Hi, please check if it worked with modify registry value "AcceptOfficeAndTahoeServers" to 1 which located at path "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters\" and capture the traffic of application nat when you perform this utility. what about reinstall TCP/IP component of this 2008 server ? Good luck.

G'day Iiyin, ta for the response, That value is currently set to 1 and has always been - the only key I've changed in that location is BasicAuthLevel. I've managed to convince the powers-that-be here to let me access the webdav drive through a samba share so I've got the functionality I need. At this point I need to move onto the next task and don't have time for figuring out what went wrong here. Thanks for your time though, cheers - v
