如果在Windows.NETServer上安装的SQLServer2000中运行链接服务器查询，可能会返回下列错误（即使MSDTC正在该服务器上运行）：
症状如果在Windows.NETServer上安装的SQLServer2000中运行链接服务器查询，可能会返回下列错误（即使MSDTC正在该服务器上运行）：Server：Msg8501，Level16，State3，Line3 MSDTConserver'servername'isunavailable.在SQLServer错误日志中，您会发现由运行该查询的spid引发的下列错误：ResourceManagerCreationFailed：ResultCode=0x8004d01c原因这是设计使然。如果在"本地系统"帐户下运行"分布式事务处理协调器服务"就会发生此错误。解决方案最近为了提高RPC安全性对DTC所做的更改要求MSDTC作为"NTAuthority\NetworkService"运行。这是。NETServer的默认选项。在WindowsNT和Windows2000中，默认情况下MSDTC服务是在"本地系统"帐户下运行的。
警告："注册表编辑器"使用不当可造成严重问题，这些问题可能需要重新安装操作系统。Microsoft不保证能够解决因为"注册表编辑器"使用不当而产生的问题。使用"注册表编辑器"需要您自担风险。
若要将MSDTC服务帐户从"本地系统"更改为"NTAuthority\NetworkService"，请执行下列步骤：1.运行regedt32，浏览至HKEY_LOCAL_MACHINE\Software\Microsoft\MSDTC.添加一个DWORD值TurnOffRpcSecurity，值数据为1.2.打开命令提示，运行"netstopmsdtc"，然后运行"netstartmsdtc".3.转至"组件服务管理工具".
a.浏览至"启动管理工具".
b.选择"组件服务".
c.展开"组件服务"树，然后展开"我的电脑".
d.右键单击"我的电脑"，然后选择"属性".
e.在MSDTC选项卡中，确保选中了下列选项：网络DTC访问网络管理网络事务XA事务另外，"DTC登录帐户"一定要设置为"NTAuthority\NetworkService".
f.单击"确定".这样将会提示您"MSDTC将会停止并重新启动。所有的依赖服务将被停止。请按'是'继续".单击"是"继续。
g.单击"确定"关闭"我的电脑"属性窗口。
4.再次运行regedt32，浏览至HKEY_LOCAL_MACHINE\Software\Microsoft\MSDTC，然后删除TurnOffRpcSecurity项。现在您的MSDTC服务应该在"NTAuthority\NetworkService"帐户下运行了，并且不会再出现该错误。
更多信息当"MSDTC安全性"配置下的"网络DTC访问"禁用时，如果运行链接服务器查询则会返回下列错误：Server：Msg7391，Level16，State1，Line2TheoperationcouldnotbeperformedbecausetheOLEDBprovider'SQLOLEDB'
wasunabletobeginadistributedtransaction.[OLE/DBproviderreturnedmessage：Newtransactioncannotenlistinthespecifiedtransactioncoordinator.]
跟踪标记7300打开时：Server：Msg7391，Level16，State1，Line2TheoperationcouldnotbeperformedbecausetheOLEDBprovider'SQLOLEDB'
wasunabletobeginadistributedtransaction.[OLE/DBproviderreturnedmessage：Newtransactioncannotenlistinthespecifiedtransactioncoordinator.]OLEDBerrortrace[OLE/DBProvider'SQLOLEDB'ITransactionJoin：：JoinTransactionreturned0x8004d00a].
MSDTC服务一定要按照上面"解决方案"一节中的说明进行设置，才能防止此错误。
再现现象的步骤
1.转至"启动管理工具服务".
2.右键单击"分布式事务处理协调器"服务，转至"登录"选项卡，选择"登录身份"下的"本地系统"帐户。
3.停止然后重新启动该服务。
4.从查询分析器，运行下列脚本：execsp_addlinkedserverremote1execsp_setnetnameremote1，
