I am trying to run Shared Folders under a different domain user according to one of user's answer for my other question How do you know who or what is locking a remote file?

runas /user:domain\user fsmgmt.msc

Even though running fsmgmt.msc by itself works fine, I am not able to run it when combining with runas. (domain\user <-- I am using a valid user name)

C:\>runas /user:domain\user fsmgmt.msc
Enter the password for domain\user:
Attempting to start fsmgmt as user "domain\user" ...
RUNAS ERROR: Unable to run - fsmgmt.msc
2: The system cannot find the file specified.

Is that intentional or am I supposed to put location of fsmgmt.msc in PATH environment variable? Questions: - How was I able to run fsmgmt.msc without updating PATH? - Is it possible to runas a different user for fsmgmt.msc?


Try running MMC instead:

runas /user:domain\user "mmc fsmgmt.msc"

Perhaps it was not in your path...


runas /user:domain\user %systemroot%\system32\fsmgmt.msc

  • It was in my env. path. And I didn't know that I could invoke a command through env. variable names... Thank you for your answer, MathewC. – Sung M. Kim Jun 10 '09 at 18:12

I am providing you the steps that worked via GUI

Please search for fsmgmt.msc in the search bar and open the file location by right clicking on it.

Then please try to Hold down the shift key and right click on the application/program or shortcut which you wish to open via different credential
