Windows Server备份2008 R2错误

我正在尝试在Server 2008 R2框中将Windows Server备份设置到不同子网上的远程服务器。正在备份的服务器位于域中，远程服务器位于专用于备份存储的工作组中。在远程服务器上有一个与备份服务器的域帐户类似的本地用户帐户。

尝试设置备份我到达凭证框，然后出现错误“Windows Server Backup无法访问远程共享文件夹。login失败：指定的帐户密码已过期”。我已经检查过帐户，它被设置为永不过期。我甚至重置了密码，以确保这是正确的。

在远程服务器上，我得到的安全日志中：

It is generated on the computer that was accessed. The subject fields indicate the account on the local system which requested the logon. This is most commonly a service such as the Server service, or a local process such as Winlogon.exe or Services.exe. The logon type field indicates the kind of logon that occurred. The most common types are 2 (interactive) and 3 (network). The New Logon fields indicate the account for whom the new logon was created, ie the account that was logged on. The network fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases. The impersonation level field indicates the extent to which a process in the logon session can impersonate. The authentication information fields provide detailed information about this specific logon request. - Logon GUID is a unique identifier that can be used to correlate this event with a KDC event. - Transited services indicate which intermediate services have participated in this logon request. - Package name indicates which sub-protocol was used among the NTLM protocols. - Key length indicates the length of the generated session key. This will be 0 if no session key was requested.

任何想法，为什么这是行不通的？
