When exploring a share served by Samba 3.0.8 from Windows 2000, explorer will frequently lock up for exactly 10 seconds. A packet capture reveals that windows tries to open a directory as a file (create andx request) with samba responding STATUS_FILE_IS_A_DIRECTORY. After a few attempts of create andx windows waits for 10 seconds and then creates a new connection to samba and everything works again for a little while and then the whole process repeats. Why is windows treating a directory as a file, when requesting information for the path samba indicates that it is a directory. Is this an explorer bug? The packet dump can be found at http://devcentre.dwl.co.uk/~dammj/lockup.dump The first erroneous request is in packet 43, the 10 second pause starts after packet 87. Andreas Damm.
