无法 激活 Office SharePoint Server 发布基础架构

我在激活 Office SharePoint Server 发布基础架构 功能的时候出现无法访问的问题。我在server的log中查看到错误信息如下，请问可能是什么问题啊？Event log message was: '未能设置计划排定作业定义。页面计划排定将不能成功。'. Exception was: 'System.Security.SecurityException: 拒绝访问。 at Microsoft.SharePoint.Administration.SPPersistedObject.Update() at Microsoft.SharePoint.Administration.SPJobDefinition.Update() at Microsoft.SharePoint.Administration.SPWorkItemJobDefinition.Update() at Microsoft.SharePoint.Publishing.Internal.RootProvisioner.<>c__DisplayClass5.<AddSchedulingJobDefinitions>b__4() at Microsoft.SharePoint.SPSecurity.CodeToRunElevatedWrapper(Object state) at Microsoft.SharePoint.SPSecurity.<>c__DisplayClass4.<RunWithElevatedPrivileges>b__2() at Microsoft.SharePoint.Utilities.SecurityContext.RunAsProcess(CodeToRunElevated secureCode) at Microsoft.SharePoint.SPSecurity.RunWithElevatedPrivileges(WaitCallback secureCode, Object param) at Microsoft.SharePoint.SPSecurity.RunWithElevatedPrivileges(CodeToRunElevated secureCode) at Microsoft.SharePoint.Publishing.Internal.RootProvisioner.AddSchedulingJobDefinitions(SPSite site) The Zone of the assembly that failed was: MyComputer' For more information, see Help and Support Center at

 

本以为是Window Sharepoint services 定时计划任务服务的问题，迫不及待的对“windows sharepoint services timer”服务进行了重启操作后，再次对office sharepoint server发布基础架构 功能进行激活，发现还是出现了同样的错误，希望各位有碰到此问题的大虾们给予答复下，谢谢了！
