can't access shared folder from Windows 7 client

[guest]

I created a couple of new folders and enabled sharing. This worked as expected from an XP client PC: opening up \\whsserver\newshare worked fine. Yet when I try to do the same thing from my Windows 7 PC, I get a "network error: Windows cannot access \\whsserver\newshare. You do not have permission to access \\whsserver\newshare.Contact your network administrator to request access."

The Windows 7 client can access the default shared folders like Music, Photos, etc, but not the newly created folders.

Ironically, the WHS server was set up using the Windows 7 PC.

Update: I deleted the old credentials for the server at Control Panel\All Control Panel Items\Credential Manager. Logged out and back in. The shares are now accessible.

Windows caches permissions when you first access the server's shares, so if you create a new share, you normally have to log off and back on to your workstation for the updated credentials to apply. Deleting the old credentials in Credentials Manager works, but really isn't needed.
