Hi, We have a Windows 2003 Server Enterprise x64 SP2 system and I am trying to navigate to a SharePoint Document library using a UNC, example: \\enhanced2.sharepoint.hp.com\teams\CSM\leaderscorner\tsmetrics\tsdometrics\americas\WeeklyScorecards The problem is, that Im being prompted for credentials. After some research it would appear the following technet article would solve the problem by enabling the use of WebDav Redirector Basic Authentication - http://technet.microsoft.com/en-us/library/cc787023(WS.10).aspx However after creating the following registry keys and values as the article describes, the problem still exists: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services \WebClient\Parameters\UseBasicAuth (DWORD) = 1 HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows \CurrentVersion\ Internet Settings\DisableBasicOverClearChannel (DWORD) = 0 The bottom line would be, that it appears that thru the Windows 2003 SP2 that WebDav Redirector Basic Authenication has been disabled not allowing the login credentials to be passed to the SharePoint (WebDav) server. Note: We another Windows 2003 Server in the same computer room where this problem does not exist, so it does not appear to be a permission issue in the SharePoint document library. Anyone run across this before and/or knows how to fix it? Thanks in advance, Mark
