SMB issues with Win7 on 2003 R2 Domain
Hi, I am trying to track down an issue am having with Win7 when browsing and copying files to my shares hosted on a Win2k3 R2 file server. When I copy large files (over 1mb) to any root of target folders on my DFS (using DFS-R), I receive the following error: 0x8007003B An unexpected network error occurred. (was copying Wildlife.wmv file found in shared videos). However if I then go into a sub directory and try to copy the file it works. I've used wireshark to capture SMB traffic during the attempted file transfer to a root folder share: 3696 4.705854 172.16.0.1 172.16.1.103 SMB Trans2 Response, QUERY_FILE_INFO, Error: STATUS_INVALID_HANDLE 3697 4.706245 172.16.1.103 172.16.0.1 SMB Trans2 Request, QUERY_FILE_INFO, FID: 0x0000, Query File Standard Info 3698 4.706634 172.16.0.1 172.16.1.103 SMB Trans2 Response, QUERY_FILE_INFO, Error: STATUS_INVALID_HANDLE 3699 4.707221 172.16.1.103 172.16.0.1 SMB Pipe WaitNamedPipe Request 3700 4.707404 172.16.0.1 172.16.1.103 SMB Trans Response, Error: STATUS_OBJECT_NAME_NOT_FOUND 3708 5.792863 172.16.1.103 172.16.0.1 SMB NT Create AndX Request, FID: 0xc001, Path: \home\Wildlife.wmv I’ve also noticed errors with SMB on the root of a target folder on my DFS shares that results in SMB not settling, it will just keep looping UNLESS I try to copy something resulting in the error mentioned above: No. Time Source Destination Protocol Info 377 40.236911 172.16.1.103 172.16.0.1 SMB Trans2 Request, FIND_FIRST2, Pattern: \home\* 379 40.238204 172.16.0.1 172.16.1.103 SMB Trans2 Response, FIND_FIRST2, Files: . ..

I’ve tried this on a fresh install of Win7 Pro and currently running the beta of service pack 1 (from which these results are from); the server is running service pack 2. Any ideas? Michael
