"Access is Denied" Dos prompt error!

Reece · 08-04-11, 06:05 PM

I have had this problem for several months or more, in a dos shell (window) trying to run any applications such as ipconfig, chkdsk, results in "Access is Denied", can run dos commands such as "dir" etc!

I have tried restoring permissions to the system32 folder, restoration is restored but didn't fix the problem.

Any ideas on this problem?

Edit:
I have just checked the "Prevent access to 16-bit applications" policy and is "Not Configured", tried changing to Disabled but no change!

I'm using XP Pro.

Well this is weird, if I copy cmd.exe to any other folder than Windows\System32 and execute a dos window from here everything works 100%, so that is one way out

but it seems weird since ipconfig.exe and chkdsk.exe reside in the Windows\System32 folder yet they will execute within the dos window with no problems!!

Surely this has to be access rights to the System32 folder?

this might help the access denied problem for cmd.exe and ipconfig

Good thought but it is definitely not that, however I believe it is a Group Policy that is causing this issue, just that there are so many variables!

I was thinking NTFS permissions; might get around it by giving your user account more permissions for the system32 folder.

Never had such issues though, always used administrator accounts and the first thing I disable in Vista/Win7 is UAC, so not going by experience in this case.

Run rsop.msc in the run cmd and see what is enabled in the group policy.

Are you a local administrator?

I ran that and everything is "not defined", blank or not set!

Wouldn't know, I am the only user!
