After awhile, my connections from my PC to my samba server end up with a
red "X" in them (share disappeared) if I leave my explorer window
open.
If I click on these, they "wake up" and continue to function
(and
the red X's go away). If I close my explorer window (while the red X's
are there) and reopen it , they are gone. An attempt to reestablish
these dropped connections is immediately successful.
This is obviously a connection persistence issue and I've tried setting
both keepalive= and SO_KEEPALIVE (individually, of course) to no avail.
Any ideas?
My installation is samba 2.2.8 running as a daemon (not inetd) on
Solaris 8 configured to use a WINS server and provide authentication via
a PDC (same host as WINS server). I do have an lmhosts file in the
samba /lib directory with the PDC/WINS server address in it.
My globals section;
[global]
workgroup = WORKGROUP
netbios name = SAMBASERVER
security = SERVER
encrypt passwords = Yes
password server = pdc
lanman auth = No
log level = 2
log file = /usr/local/depot/samba-2.2.8/var/%m.log
deadtime = 5
max smbd processes = 5
socket options = IPTOS_LOWDELAY TCP_NODELAY SO_KEEPALIVE
load printers = No
show add printer wizard = No
preferred master = No
local master = No
domain master = No
wins server = [IP address of WINS/PDC server]
follow symlinks = No

/It's looks like the resolution to this problem is setting the deadtime global option to 0 (at the cost of resources). Although it defaults to 5 (minutes), a stale connection is actually tossed under 1. I will continue to experiment with this and contribute further should information of value is obtained.

I have had a similar problem and found this during some searches. I havent tried it yet but will try on monday in the login scripts SYMPTOMS: You find that the network drive mapping may be disconnected after 15 minutes of inactivity and Windows Explorer may display a red "X" on the icon of the mapped drive. However, if you double-click it reconnects quickly. RESOLUTION: by default, idle connections will be dropped after 15 minutes. To modify idle time, at a command prompt using net config server /autodisconnect: minutes. For example, to set the Autodisconnect value to 30 minutes, you would run the following command line: net config server /autodisconnect:30. If you would like to turn Autodisconnect off, do net config server /autodisconnect:-1.
