HI, I have an apache running on 2003 server for web requests, and it is also a domain controller. I have also setup DFS on this server and it seems the DFS is conifged smoothly. Howerver when i browse the DFS root, it keeps asking me password , even i used the administrator password and sure it is correct. I have no clue why this happen and i read the apache log, seems there is some entry related about this: 123.8.23.70 - - [10/Mar/2008:09:32:55 +0800] "PROPFIND /dcbackup HTTP/1.1" 405 1042 , which, the dcbackup is the root of the DFS. i have done a bit of research of "PROPFIND" and found that it is about webdav request. Actually i don't understand why is it about Webdav issue. I just want apache to server web requests, and the DFS works in our local network. Please help , i have searched quite a long time on the internet still no clue how to solve this. And now i have to ask question, many many thanks. daniel
