關(guān)于Outlook 客戶端無法解析Exchange 服務(wù)器的解決方法 問題現(xiàn)象：用戶使用Outlook mapi 客戶端，在配置郵件配置文件訪問exchange 服務(wù)器的時(shí)候，出現(xiàn)無法解析服務(wù)器名的錯(cuò)

關(guān)于Outlook 客戶端無法解析Exchange 服務(wù)器的解決方法 問題現(xiàn)象：

用戶使用Outlook mapi 客戶端，在配置郵件配置文件訪問exchange 服務(wù)器的時(shí)候，出現(xiàn)無法解析服務(wù)器名的錯(cuò)誤

用戶使用Outlook 利用pop 訪問郵箱，在發(fā)送郵件的時(shí)候，出現(xiàn)無法解析收件人姓名的錯(cuò)誤

用戶使用owa http方式訪問郵箱正常

原因分析：

客戶端計(jì)算機(jī)安裝了個(gè)人防火墻軟件，關(guān)閉了客戶端的一些協(xié)議和端口，導(dǎo)致客戶端和exchange 通信出現(xiàn)問題

解決方法：

按照如下標(biāo)準(zhǔn)設(shè)置，在客戶端計(jì)算機(jī)上進(jìn)行檢查，如果出現(xiàn)和標(biāo)準(zhǔn)配置不符的情況，必須進(jìn)行更改：

1. RPC_Binding_Order

The RPC_Binding_Order entry is created when you install the Outlook client or Exchange Server. The RPC_Binding_Order entry determines the protocol sequence that is used when Outlook RPC communications are initiated.

Note The RPC_Binding_Order entry is not created in Microsoft Exchange Server 2003 or in Microsoft Exchange 2000 Server. This entry is only created in Microsoft Exchange Server 5.5 and in earlier versions of Exchange.

You can find this entry in the following registry key:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftExchangeExchange Provider

By default, the Rpc_Binding_Order entry contains the following value data: ncalrpc,ncacn_ip_tcp,ncacn_spx,ncacn_np,netbios,ncacn_vns_spp

If the setting is incorrect, please correct the value according to the default setting.

2. ClientProtocols

The ClientProtocols registry subkey is created when you install the operating system and the first network protocol. The ClientProtocols registry subkey contains entries that determine the protocols that can be used by the client operating system to connect to Exchange Server. Outlook can determine the RPC protocol to send; this registry subkey determines if the operating system supports that protocol. You can find this subkey in the following registry key on Microsoft Windows 2000 and Microsoft Windows XP:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftRpcClientProtocols

By default, the ClientProtocols subkey contains the following registry entries for TCP/IP:Name Type Data

ncacn_http REG_SZ rpcrt4.dll

ncacn_ip_tcp REG_SZ rpcrt4.dll

ncacn_np REG_SZ rpcrt4.dll

ncadg_ip_udp REG_SZ rpcrt4.dll

3. Verify the version of the DLL file

If all the registry values exist, verify the version of the RPC DLL file that is on the computer. The version of the RPC DLL file must match the version and the build number of the Windows operating system on the computer.

To determine the version and the build number of the Windows operating system on the computer, follow these steps.

1. Click Start, and then click Run.

2. In the Open box, type winver.

3. Make a note of the version and the build number.

To determine the version of the .dll file, follow these steps:1. In Windows Explorer, locate the RPC .dll file in the WindowsSystem32 folder.

2. Right-click the file, and then click Properties.

3. Click Version.

4. Note the file version.

The file version must reflect the build number of the Windows operating system on the computer.

If the version of the .dll file does not match the version and the build number of the Windows operating system on the computer, replace the .dll file with the correct version. To do this, follow these steps:

1. Locate the correct version of the .dll file.

You can find the file on the Windows CD, in Windows service packs, or on another computer that is running the same build of Windows.

2. On the computer that is experiencing the problem, locate the .dll file.

3. Change the extension of the .dll file to .bak or .old.

4. Copy the correct .dll file to the computer that is experiencing the problem.

5. Restart the computer.

6. Test Exchange Server connectivity. 問題狀態(tài)：
