Vista - exception when calling a method: object is read-only

Hello all,

What does the error below mean? not sure what why this object would be
read-only, or what that has to do with calling a method on it.

PS Z:\> $vaultServer = new-object
Symyx.Framework.Vault.VaultServer("localhost")
PS Z:\> $vaultServer.Logout()
Exception calling "Logout" with "0" argument(s): "Object is read-only."
At line:1 char:20
+ $vaultServer.Logout( <<<< )

It means that the object you obtained cannot be modified. When I've seen
this before it usually means that the object doesn't actually do what I
thought it did

As to why that is - a couple of ideas:

1) does the user account you are using have permissions to whatever the
object represents

2) I presume there is a Logout() method

3) put the object through get-member and see what it returns

4) remember psbase and the other object qualifiers - see if using them can
help

Thanks Rich,

(1) get-member returns all the properties and methods on this object, no
problema, including Login, Logout.
(2) i'm signed on to the box as an admin user. This object is simply an
object in a library that i've loaded. it doesnt do anything but call a web
service to authenticate.
(3) is there a way to get better error messages?
