Microsoft已经提供了对应的hotfix来解决上述问题，不过需要联系Microsoft Support Services来获取hotfix。我没有在网上发现该hotfix的下载。
目前，Microsoft SQL Server 2004 Service Pack 4.0（处于测试阶段）还没有正式推出，郁闷。只好通过Query Analyzer使用SQL Script脚本来完成，如：
ALTER TABLE AppRemotingLogger ALTER COLUMN Message VARCHAR(800)
（修改数据表AppRemotingLogger的Message字段）
Updated：
根据bengxia的指点，可以从如下的URL下载到了SQL2000-KB810185-8.00.0878-ENU.exe 。下载地址为：http：//support.microsoft.com/?kbid=838166
上述hotfix修复了该bug。
