SMB issues with Win7 on 2003 R2 Domain

hi,
trying track down issue having win7 when browsing , copying files shares hosted on win2k3 r2 file server.

when copy large files (over 1mb) to root of target folders on dfs (using dfs-r), i receive following error: 0x8007003b unexpected network error occurred. (was copying wildlife.wmv file found in shared videos). if go sub directory , try copy file works.

i've used wireshark capture smb traffic during attempted file transfer root folder target:

3697 4.706245    172.16.1.103          172.16.0.1            smb      trans2 request, query_file_info, fid: 0x0000, query file standard info

i’ve noticed errors smb on root of target folder on dfs shares results in smb not settling, keep looping unless try copy resulting in error mentioned above:

any ideas?
