使用System.DirectoryServices更改密码时收到错误

Question

I've a web service deployed on one of the servers which internally uses System.DirectoryServices to change password using following code :

            DirectoryEntry obDirectoryEntry = GetCurrentUserDirectoryEntry();
            obDirectoryEntry.Invoke("ChangePassword", new object[] { sOldPassword, newPassword });
            obDirectoryEntry.CommitChanges();
            obDirectoryEntry.Close();

This web service is working fine when hit from a particular different domain, but fails with following error when hit from some other :

Configuration information could not be read from the domain controller, either because the machine is unavailable, or access has been denied.

What could be the reason of this? And what is the workaround?

Thanks a lot, Ishan

Answer 1

Need more info about the particular network setup, but a workaround would be to specify the DomainController that works.

In your GetCurrentUserDirectoryEntry() method, you can use the overload:

var user = new DirectoryEntry("LDAP://WorkingDomainController", ...);
