Permission issues with 10.5 AD clients on win2003 server

We have recently migrated all our OS X (10.4.11 and 10.5) local accounts over to AD accounts, with permissions controlled by user account and security groups in AD. With all the 10.4.11 accounts we have not had any issues with permissions to folders on the 2003 shared drives, when I update any of the users to 10.5, the have some issues accessing only some of the folders on the server and cannot color code a folder or file as well. As soon as I log that same user account into a 10.4.11 machine, i have no issues accessing the same folder or color coding the folders/folders? Some background info: - No OD/OS X Server involved - No AD account changes in past yr, as far a as security groups and permissions - I have had server team push down permissions from top folder down to all below - all accounts are AD account - NO LOCAL accounts - all 2003 shared drive mounted via SMB - server team will not activate or load any other protocols on servers - No problem using AD accounts to change passwords - time on all machine in question are up to date with servers Any help would be GREATLY APPRECIATED, we have designers who color code folder as to status of production and this is seriously hampering their production. If more info is needed please ask - thanks in advance for any assistance
