windows 156 error

Hi All,

We are experiencing another 156 error (they are a pain) on a Windows client backup.

When I logged into the client to check that this list writers stable for some reason I recieved the error below.

C:\>vssadmin list writers
 

'vssadmin' is not recognized as an internal or external command,
operable program or batch file.

I have attached logs  *bfis and bpcd" I have viewed them and can't find anything specific. If someone can take a look and see if they can let me know.

Here is some info

Client Server Windows 2003 SP2

Netbackup client 7.6.0.1

Thanks
