Windows Server 2008 share not accessible to a particular user account

[DConnell Member]

I have a share on the server for the finance dept, and all of their user accounts are configured to have access to it. They're all part of the "Finance" group, which is set up as "co-owner" of the folder, and most of them can access with no problem. One account cannot access the share, with the message that it has "insufficient rights" to the folder. It's included in the Finance group, and when that didn't give the account access I added the account explicitly as co-owner.

The account in question is the "Win16" account.

You can see here the user permissions should allow Win16 access.

See anything I've missed? Or any suggestions as to what else could be preventing access? The computer in question is running Win XP Pro. (Yes, I know. I'm slowly working to get the business on 7. :) )

Check your advanced sharing

check to see if win 16 is in any sort of denied group.

Check your effective permissions for win 16.

Yeah the effective permissions is a great tool for troubleshooting - but your looking at share permissions there, what are the ntfs permissions on the folder your sharing?
