Mavericks 10.9.5 cannot connect to windows share on server 2008r2 via SMB or CIFS

hey anyone,

on several macs at a client all running Mavericks 10.9.5. everything was working smooth.

then all of a sudden anytime i try to connect to a specific share on server 2008r2 via SMB or CIFS.

it connects (with authentication). but the share wont open. and crashes the finder. everytime.

i can open other shares on the same server without any problems.

i've tried this on several machines all with a similar result.

all permissions on the server are correct as well as on all Macs.

anyone have any similar issues and a way to get the finder from crashing?

will updating Yosemite help? or create more problems with SMB connectivity

help
