Re: win95 + linux oplock error, even with kernel oplocks = no.

This might not be the solution, but since you are so desperate I'll give it a shot.  ;-)

We had the excact same problems in the log as yours with a small network of  our own.  
We figured the problem was with the speed and duplex of the network cards, and this again 
generated the samba error messages.  

- Our Solaris box was up with 100mhz/full duplex 

and hub'ed (100mhz hub) to a 

- NT-box with 100mhz/full duplex.   

This would seem quite nice in theory, but it seems that the hub could not handle the 
full-duplex part.  So we put both to 100Mhz/half-duplex (which really is a no no with 100Mhz 
speeds) and we had no problems with the transfer nor any error messages in the samba-log 
anymore.

Another solution might be to 'switch' the network components.  Put a switch there instead of a 
HUB.  You might then see that 100Mhz/Full Duplex would work.

Hint: if you can, never use 'auto-negotiate' on speed nor duplex in any op-sys environment.

You can check what speed and duplex you have (in solaris anyway) with this command: 
dmesg

And you can set the unix-network speed and duplex in /etc/system (dunno if its the same in 
Linux).  Search for "hme_adv_100fdx_cap" on the net and you should get some manual hits 
for it i would guess.
