Resolved Command Shell Not Recognizing Commands

XP Pro SP3

I have a couple of minor issues which I am trying to resolve which are on another post, but when trying to work through the suggestions kind people have offered there I need to use use the CMD function in the Command Shell but can't get it to work (it used to in the past).
The message I get when entering a command eg. 'IPConfig', 'Ping' or any others as far as I can see is;
''IPConfig' is not recognized as an internal or external command, operable program or batch file'.
Searching for possible reasons for this (Google etc) most people reckon it is likely to be a 'Path' problem or corruption but I need a bit of help in checking and, if necessary, correcting this.
If I go to 'System Properties>Advanced>Environment Variables' and look at the Path in the System Variables I see;
C:\WINDOWS\System32;C\WINDOWS;..
If I highlight this to Edit it I get the Variable Value shown as;
%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\wbem

Is this all as should be ?. If it is then what else is the possible cause of the commands not being recognized ?.
Would greatly appreciate some help.

 

I get:-
Path = %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\wbem

 

Yes Arie I am sole 'Owner/Administrater.
So sorry to be a 'pain' but how do I create a new account ? Do you mean User Account, if you do then I think I can do that.

 

You're a star Arie, changed the Path to the value you said it should be and all seems to be well with the Command Shell now, didn't need to create a new user account. Thank you so much. I can get back to original problem and my thread about IPSec Services now.
I wonder what caused the Path to become corrupted, the Command Shell used to be working ok.
