Issue:
Three WinXP Pro boxes using Offline Files disconnect from all Samba shares when a user either performs a synch or accesses a file on the share with offline files enabled. About half the time, being able to reconnect for any length of time requires a reboot of the WinXP machines. Disabling the Offline Files in Windows alleviates the problem.
Background and Network Environment:
I recently completed a migration from an old Linux box running Samba 2.x to a new one running RH ES3 and Samba 3.0.7-1.3E.1. User PCs are about 10 Win98SE PCs and about 12 WinXP (with SP2) PCs. There were no problems using the Offline Files using the old Samba 2.x server.
Migrating the shares was done in 2 stages. The first stage was migrating a single share on 8 WinXP and 2 Win98 machines. Additionally, for my own PC, I also migrated my home directory, which has Offline Files enabled. All went well and there were no problems for 2 weeks. Two of the XP PCs I'm currently having trouble with were in this group, but they had no problems until the next stage of the migration.
Stage 2 was migrating the rest of the shares, which included the users home directories. The XP “My Documents” folder is redirected to a folder in the user’s Linux home directory, and Offline Files enabled.
Specifically:
Linux home directory = /SambaSharesB/%username%
Mapped Drive on XP = H: = \\F2\homes
XP “My Documents” icon redirected to H:\documents
Offline Files enabled for “My Documents”
Of the 12 XP PCs migrated, 9 work flawlessly but 3 will disconnect all shares from F2.
A user log file snippet and the contents of my smb.conf file follow.
The following log snippet (log level = 2) shows an Excel file being opened and closed several times in very rapid succession then his home share (service: dray) being authenticated and closed a few times, then all shares. New PIDs were even generated.
I found the following entry interesting:
[2005/01/10 17:31:21, 2] smbd/service.c:make_connection(752)
[homes] share not available for this user because it was not found or created at session setup time
Anyway, here are the contents:
