[Samba] smbclient timeout?

[Julius Junghans]

Hi,

i can see some systems with the smb kde ioslave (smb:/ in konqueror) that i 
can't connect to even with smbclient, error message is:

timeout connecting to 192.168.0.2:445
timeout connecting to 192.168.0.2:139
Error connecting to 192.168.0.2 (Die Operation wird bereits ausgeführt)  - 
free translation "operation in progress"
Connection to 192.168.0.2 failed

sometimes ofcoure througb the smb nature the browse list is outdated, but nmap 
tells me that the machine is online?

if i tell samba to be the lmb for this workgroup with:
os level = 255
preferred master = yes

i can see in wireshark that browser election takes place, and the pc in 
question releases the workgroup so that my pc is the new local master 
browser.

Any ideas?
