Jenkins can't access mounted driver

My Jenkins server is running in Tomcat on Windows 2008 server. I have set up a NFS server on CentOS, Win2008 server can access the NFS shared folder via mount command. I tested it when running as administrator user on Windows. I mount the folder as Z driver on Windows 2008 server. But my job in Jenkins said it can't find the Z driver, I guess Jenkins web app might have not the enough permission to access Z driver. Please see the error message from Jenkins

Console output:

Building in workspace C:\.jenkins\workspace\upland-install
[upland-install] $ cmd /c call "C:\Program Files\Apache Software Foundation\Tomcat    6.0\temp\hudson4487584210513580576.bat"

C:\.jenkins\workspace\upland-install>xcopy Z:\upland_release\364 d:\tmp /S

How to fix this problem? Install Jenkins as a windows service?

Solution

A couple solutions:

You need to run your Jenkins process in the same user context that you mounted the drive in. This works, but isn't always the desired solution.
Run the job on a Jenkins slave that is started in the context of the user with the mounted drive. Not always possible if slave machines aren't available.
Use the Publish Over CIFS plugin
