【问题描述】：
我使用启动和远程访问权限执行了 DCOMCNFG，授予我在每个节点上的本地登录权限。在 root 和远程机器上安装 OpenMPI_v1.6.1-x64。已在目标节点中指定 .exe 的路径。但是在使用 mpirun 从根节点运行 .exe 时。我收到以下错误：
D:\x64\Release>mpirun -np 2 -hostfile myhostfile.txt MPISample.exe
connecting to n1234
username:toney.mathew
password:********
Save Credential?(Y/N) n
[n1205:04420] Could not connect to namespace cimv2 on node n1234. Error code =-2147023174
--------------------------------------------------------------------------
mpirun was unable to start the specified application as it encountered an error.
More information may be available above.

更具体地说，我在两个节点中都使用 windows7-64bit 操作系统，登录的用户相同。

不适合 SO，更可能适合 superuser 或 serverfault。
