Error : disabled command prompt !

[jbosch]

Hi,

On our windows 2003 server, Plesk is suddenly not working anymore.
The strange thing is, we never changed anything ! It just happened overnight...

When we login to plesk, (the login screen is working), we get a blank page with the following error:

"Fatal error: Execute C:\Program Files (x86)\SWsoft\Plesk\admin\bin\vzutil.exe failed:
The command prompt has been disabled by your administrator.

Press any key to continue . . .
in C:\Program Files (x86)\SWsoft\Plesk\admin\plib\common_func.php3 on line 3097"

But this is a bogus error message !
The command prompt is working fine ! We can run all scripts, bat files and exe files from the command prompt. But if we try to run some of the Plesk exe´s from the command prompt, it gives the above message.

Anybody nows a solution ?

May be you have included you server into a domain? In this case domain policy can cause such issue.

No, the server is not in a domain.

Like I said, I can do anything from the command prompt, except the Plesk executables.

It might be a problem with the PHP configuration (maybe ?)

But I'm not sure...

Easy fix!

The SYSTEM-account has lost permissions on c:\windows\system32\cmd.exe
Goto the system32 folder and reassign the rights to the SYTEM-account.

Not that easy...

System account has full rights... Still not working.
Even tried to temporarely set full right on the everyone account. Still didn't work...

Anyone else ?

That's odd... I have had the exact same problem just today on my new installed Plesk 8.1 machine. By default I have so change some stuff like:
- Reset system account credentials for cmd.exe so I can login
and
- Run the fix described in http://kb.swsoft.com/article_155_968_en.html for Horde to work

I'll check if I have archived any other solution regarding this problem.

Haven't found anything related.

Still I think it's a problem in NTFS rights.

My rights on cmd.exe
Administrators (group)- Full
INTERACTIVE (group)- Read & Execute
psaadm - Read & Execute
psaserv (group)- Read & Execute
SERVICE (group)- Read & Execute
SYSTEM (group)- Full
TelnetClients (group)- Read & Execute

My rights on vzutil.exe
Administrators (group)- Full
NETWORK SERVICE (group)- Deny all
psaadm - Read & Execute
psacln (group)- Read & Execute
psaserv (group)- Deny all
SYSTEM (group)- Full

Also check your effective rights for System on both files. It could be that some inherited rights are preventing acces, since a deny on a higher level overrules an allow.
