You do not have permissions to open this file on Excel Services

在MOSS2007中，建立一个Collaboration Portal站点。

站点的Reports下有一个Sample dashboard， 打开这个dashboard在出现
Access Denied
You do not have permissions to open this file on Excel Services



出现这个情况需要把这个站点添加到Excel Service的Trusted File Locations

此功能在Shared Services Administration: SharedServices1 > Excel Services Trusted File Locations

Add Trusted File Locations

Address 输入站点的URL， Location Type选择Windows SharePoint Services， Trust Children 钩选上Children trusted。

其他内容根据需要选择和填写。默认也可以。这样就可以了。
dashboard就可以看到了。
