Create Windows Shares from the Command Line using RMTSHARE.EXE

RMTSHARE.EXE from one of the Windows NT Resource kits makes quick work of creating shares.

Here's an example of creating a hidden, read-only share accessible only by the fictional AD group 'DOMAIN\AdminsSQL':
rmtshare \\SQLSERVERNAME\BACKUPS-RO$=E:\BACKUPS /GRANT "DOMAIN\AdminsSQL":r


Want write(change) access but still with a hidden share? Use this syntax:
rmtshare \\SQLSERVERNAME\BACKUPS-RW$=E:\BACKUPS /GRANT "DOMAIN\AdminsSQL":c


Remove the dollar sign from the end of the share name if you want the share to be visible.

Running RMTSHARE.EXE against a \\SERVERNAME with no parameters shows all the shares(including the hidden shares) available, like so:
C:\>rmtshare \\SQLSERVERNAME

Share name Resource Remark

-------------------------------------------------------------------------------
IPC$ Remote IPC
C$ C:\ Default share
X$ X:\ Default share
ADMIN$ C:\WINDOWS Remote Admin
BACKUPS-RO$ E:\BACKUPS Shared by remote command.
BACKUPS-RW$ E:\BACKUPS Shared by remote command.
D$ D:\ Default share
L$ L:\ Default share
E$ E:\ Default share
The command completed successfully.


Tested in Vista, Server 2003, Server 2000. Let me know if you find a version of Windows incompatible with RMTSHARE.EXE!

Vista x64, Windows Server x64

RMTSHARE.EXE works fine on 64-bit environments such as Windows 7 x64 and Windows Server 2008 x64 to create and manage shares - just run it from an elevated CMD prompt.

RMTSHARE.EXE is compatible with x64 BUT -

people get confused because the self extracting .EXE at the ftp site refuses to extract on x64. You can either extract the contents on a non x64 machine, or use a tool like 7zip to extract the contents.

Thanks for the clarification. 7-Zip is a great tool for creating/extracting compressed archives. I use it on my Win 7 64-bit desktop.

lol, I was just about to give up on this (failed extraction), when fortunately I read the comments!!!
Thanks!

Hey guys as a heads up on windows 7 sp1 x64 and windows server 2008 r2 Sp1 x64 it does not work (displaying an error stating it is compatible only in a 32bit environment) this is using the one linked in this article.

RMTSHARE.EXE (not to be confused with its installer file RMTSHAR.EXE with [notice the lack of an 'E'] ) works running Win 7 x64 sp1 against Windows Server 2008R2.

I've run RMTSHARE.EXE against multiple servers, including an oddball - a Celerra CIFs server on our EMC CX4-120 SAN. The spaces in the syntax of share names can be confusing, though.

what's wrong with the good old

net share sharename=FolderName

Hello,

I've got a problem with RMTSHARE.EXE on XP SP3

Example : RMTSHARE.EXE\\%computername%\d=d:\

The command failed: -1073741819

RMTSHARE can Add and remove user in share proprieties. Net share can't do that on XP ( /GRANT no exist)

By the way, the link for download RMTSHARE.EXE isn't good.

"ftp://ftp.microsoft.com/bussys/winnt/winnt-public/reskit/nt40/i386/RMTSHAR.EXE"

RMTSHAR.EXE = PKSFX (R) FAST! Self Extract Utility Version 2.04g 02-01-93

although I have run rmtshare many times before, I seem to be having issues with it now. When running from W2K8R2 x64 with elevated command prompt, I can delete shares and change share permissions, but when I try to create a share it crashes. Has some new patch been issued to cause this?
