Hello Jie-Feng This is HIGHLY discouraging. I am appalled to find out at this stage that SCE requires the same architecture as the remote SQL Server. This is not mentioned at all on the System Requirements and Supported Platforms page at: http://technet.microsoft.com/en-us/library/bb422876.aspx It is absolutely unacceptable that SCE must be run on a 64-bit platform if using a 64-bit remote SQL database. I have already purchased and installed 64-bit hardware to move several databases from an overloaded system to this new platform. I do not have the ability or resources to move SCE to a 64-bit platform to support this undocumented requirement. Because this caveat is not listed in the above supported confiuration page, I do expect this to be treated as a "bug" and a fix to be made available to the general public. If this cannot be done through this forum, please indicate how I can submit this bug through proper channels. If this is truly the case, then I will have to tell at least a half-dozen clients to consider an alternate monitoring solution. Thank you, Keith Jakobs
