求助高手！GIS server问题！

<P>我是ArcGIS的菜鸟，最近刚学习92，用ArcCatalog和ArcGIS server Manage发布地图时均提示：Unable to start one or more service(s) due t Server has no associated SOC machines or all SOC machines are at capacity. Add a SOC machine or change the capacity of the available SOC machines. <FONT color=#000000>这是什么问题呢？有哪些解决方法啊？谢谢大家啦！</FONT></P>
