concurrent logouts hanging

[James Robnett]

   We have recently discovered a problem with our win95/samba setup.  
The clients are 486/66's the servers are:
sparc5         Solaris 2.5 [netlogon]	samba-1.9.17alpha4
alpha1000/233  OSF 3.2	   [homes]	samba-1.9.17alpha4

   Roving profiles and login scripts are enabled, share modes were
disabled on the netlogon server (it seemed to interfere with concurrent
logins).

   Everything appears to work fine except for one peculiar case which we
discovered while testing a new lab.  If the same user logs into 2 or more 
clients at the same time then only the one which logged in first can log out.  
The other client(s) will hang waiting for explorer to close.  Killing
explorer won't help, the machine has to reboot.

   According to the client logs on both servers the connections open 
normally and the closure of those connections is normal.

   We've tried turning off profiles, login scripts, all shares but
netlogon, toggling share modes, toggling fake oplocks, pretty much 
everything we could think of.... nothing helped.

   We added the 'max mux = 50' fix mentioned elsewhere though it's 
supposedly the default in samba-1.9.17alpha4 ... no help there either.

   We never see any problem with multiple users logging out as long as
they're different users.

   Here is the smb.conf from the netlogon server.  The [homes] server is 
unimportant since the problem occurs whether that server is running or 
not.

   Any input would be greatly appreciated, in general this isn't a serious
problem but it is annoying.
