CMD and UNC Paths in Login Script

[David]

I am running a .cmd file as a login script on Domain Controllers.

The script works fine on 2k boxes but every time it runs on a 2k3 box, the
following error message appears:

CMD.EXE was started with the above path as the current directory.
UNC paths are not supported. Defaulting to Windows directory.


The script still runs fine, but is there any way i can get rid of this error
message?


Thanks!

Add the following to the logon script:

REG ADD "HKCU\Software\Microsoft\Command Processor" /V DisableUNCCheck /T REG_DWORD /F /D 1

The second time it runs for a user, the message will be gone.

NOTE: REG.EXE is built into Windows XP and Windows Server 2003.
It is installed on Windows 2000 from the Support Tools folder on the Windows 2000 CD-ROM.

Alternately, store the following DisUNCCK.reg file in the netlogon share of each DC:
REGEDIT4

[HKEY_CURRENT_USER\Software\Microsoft\Command Processor]
"DisableUNCCheck"=dword:00000001


In the logon script, add
regedit /s %LOGONSERVER%\NETLOGON\DisUNCCK.reg

perhaps just beginn the script with a "cls" to get rid of the message.

That's what we do, and nobody has complained yet about it.

Add the following to the logon script:

REG ADD "HKCU\Software\Microsoft\Command Processor" /V
DisableUNCCheck /T REG_DWORD /F /D 1

That's interesting Jerold. XP, W2K3 only?
It seems not to have yet made it into a Tip. At least, a search on
DisableUNCCheck
does not hit.

Cmd.exe does not support UNC names as the current directory

All versions of NT, from NT 4.0 - NT 5.2 (and beyond).
It will make the tips soon.
