Error in creating path while requesting for new file system share for the second time

I have raised a request for new share creation. Process step which involves "Create path" , i am able to create path for the first time but when i raise request to create  anew share under same "sharedRootPath" i use to get below error related to access denied.

\LOCALJOBSERVER2 - VI.JobService.JobComponents.FileComponent - 8fbee977-b080-4811-8060-75a862b05e95: Errors occurred
Creating path \\\C$\CustomShareRoot\NFS3
[System.UnauthorizedAccessException] Access to the path '\\\C$\CustomShareRoot\NFS3' is denied.
at VI.JobService.ProcessorThread._ExecuteJob(Job job, JobResult result)
at System.IO.Directory.InternalCreateDirectoryHelper(String path, Boolean checkHost)
at System.IO.Directory.InternalCreateDirectory(String fullPath, String path, Object dirSecurityObj, Boolean checkHost)
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)

My query is if i am able to access the path C$\CustomShareRoot once and able to create  a new share under this root folder then why sytem is showing error when the request is raised again to create a new share under same root path: C$\CustomShareRoot.

Is there any property which is missing which is leading to single use of custom root path. Kindly suggest.
