We have a small Windows XP Workgroup. System "A" tried to connect to System "B". When asked, System "A" provided a username and password to log into System "B" and use it's shared drives, and checked the "Save my password" checkbox.
PROBLEM: The Username and Password given only had READ permissions on System "B", so System "A" can't write anything to System "B". This was an error -- System "A" should have used a different set of credentials that would allow read/write access to "B".
Now, how do we UNDO the read-only credentials and force System "A" to use different read/write credentials.
Why this happened: The read-only credentials are cached somewhere, so everytime System "A" tries to access System "B", those cached credentials get used. Is there any way to force Windows XP to once again ask for credentials, so that Read/Write credentials can be used?
