WebDAV访问问题

assassor1 2011-02-16 07:45:58

Exchange2003,首先用下面的代码，自动创建用户ABC,然后用WebDAV去访问http://localhost/exchange/ABC/，出现错误：The remote server returned an error: (404) Not Found.

但是，我用IE登陆http://localhost/exchange/ABC/，并输入用户名和密码后，能看到Exchange邮箱网页，关闭IE，之后再用WebDAV去访问http://localhost/exchange/ABC/就成功了。

重新创建了几个新用户都是这样的现象。先不能用WebDAV访问，用IE登陆后再关闭，就能用WebDAV访问了。

请问大家这是什么原因？是不是我用下面的代码创建的用户ABC有某些属性不对？？大家帮忙看看，谢谢了！！！

string defaultNC = ConfigurationManager.AppSettings["defaultNC"];
string alias = "ABC";
string fullName = "ABC"
string password = "!@qaz123";
string homeMDB = ConfigurationManager.AppSettings["homeMDB"];
DirectoryEntry container, user;
CDOEXM.IMailboxStore mailbox;
//This creates the new user in the "users" container.
//Set the sAMAccountName and the password
container = new DirectoryEntry("LDAP://cn=users," + defaultNC);
user = container.Children.Add("cn=" + fullName, "user");
user.Properties["sAMAccountName"].Add(alias);
user.CommitChanges();
user.Invoke("SetPassword", new object[] { password });
//This enables the new user.
user.Properties["userAccountControl"].Value = 0x200; //ADS_UF_NORMAL_ACCOUNT
user.CommitChanges();
//Obtain the IMailboxStore interface, create the mailbox, and commit the changes.
mailbox = (IMailboxStore)user.NativeObject;
mailbox.CreateMailbox(homeMDB);
user.CommitChanges();
