***RESOLVED*** ok i gained access to the drive i had the problems with. i looked under security in the shared drive that i was able to access and basically added the same access members to the drive i wasn't able to access. however, instead of adding them one by one and checking to see if i was able to gain access, i added all that were listed. i'm not sure if all are required for access purposes so i'm going to remove them all then add them one by one to see what one (or maybe all) are required. thanks everyone for your help.
