Windows Server 2008 R2下部署OCS 2007 R2 CWA碰到的一些问题和解决办法

7.6. 可能遇到的错误和注意事项
不同于在windows Server 2003和windows Server 2008平台上部署OCS 2007 R2和OCS CWA R2,Windwos Server 2008 R2和OCS 2007 R2兼容性还是差了点,以下收集了些相关的问题,希望朋友们继续多多完善。
7.6.1. code: 0-1-492
现象:
当您登录到一个 Office Communicator Web Access (CWA) 的网站时出现错误消息:"无法登录,因为您的计算机时钟设置不正确或您的帐户无效。(Error code: 0-1-492)"

7.6.2. Code:0-0-18100-2-0
现象:登录CWA客户端报错0-0-18100-2-0
原因:一般是CWA或OCS证书申请的时候有问题。
我在部署CWA时遇到过,原因是CWA01的证书是在OCS01上申请的,没有在OCS01上删除,可能OCS01上的OCS服务绑定到了这个新的证书,而不使用它原来的证书了。这种
解决方案:
使用安装向导进入配置证书步骤,重新申请和绑定证书。也可以参考Kb 或OCS部署文档使用LCSCMD.exe申请,相关KB如下。
如果是像我一样在OCS01上位CWA01申请证书,记得在OCS01上删除CWA01的证书,并重新启动下OCS01上的服务。

7.6.3. CWA不能收消息
现象:
Office communicator R2 可以收到从CWA发来的消息,但是无法回复给CWA,提示错误ID:504. Office communicator之间通讯都没有问题。CWA与CWA之间不能收发消息。

原因和解决方案:
Windows Server 2008 R2下存在这个问题,试验中困扰了我比较久。安装OCS2007R2-KB967674-x64-ucmaredist.msp(UcmaRedist.msp)可以解决这个问题,另外,我还安装了KB967674所对应的补丁。在Exchange 2010的OWA和CWA客户端集成中这个问题也比较普遍。
推荐,安装OCS 2007 r2相关的所有补比较好,尤其在Windows Server 2008 R2下 。OCS补丁列表:

To allow changes to take effect immediately, stop and restart the OCS front-end services; note that doing so will disconnect any active users.
Note:  If you install OCS 2007 R2 on Windows 2008 R2, you have to download a hotfix for UcmaRedist.msi; UcmaRedist.msp from the Microsoft Office Communications Server 2007 R2 Hotfix KB 968802. If you don't, everything works except IM communication back to OWA, you would receive an Error id: 504. With UcmaRedist.msp installed, the issue is resolved. {this point added Dec 5, 2009 thanks to input from Jahad Suboh who commented on my blog to add this point of additional accuracy!}

The 501 errors (when the OWA integrated IM can send, but NOT receive) was totally because my OCS 2007 R2 was patched to KB967674, and the bits released earlier in this thread were not.  (boo!)
Patched, rebooted, and CWA/OWA works!
