I first sent a message about this problem 8 days ago, but have still not resolved
it. However, I now have a much clearer idea of what is happening, so can provide a
better description.
We have a SAMBA_2_2_5 PDC (using LDAP) with dozens of XP PCs as members of the
domain. This all seems to work OK as such. We also have on the same network loads
of XP PCs which are not members of the domain, but are just members of various
workgroups. Our problem is that there are times when (so it seems to me) some of
these non-domain PCs are thrashing away trying to get at the IPC$ share on one or
more of the PCs which are members of SAMBA's domain.
I have used a sniffer on the network connection of a domain member while this is
happening (this PC was sitting on the XP login window at the time). This is the
sequence of packets to/from the PC:
>From non-domain PC: SMB command 73 (Setup Account AndX)
To non-domain PC: SMB response to 73 with status code C0000016
>From non-domain PC: SMB command 73 (Setup Account AndX)
To SAMBA PDC: SMB command 2F (Write AndX)
(containing username of user logged in on non-domain PC.)
>From SAMBA PDC: SMB response to 2F with status code 0 (OK)
To SAMBA PDC: SMB command 2E (Read AndX)
(no sign of username in this packet)
>From SAMBA PDC: SMB response to 2E with status code 0 (OK)
To non-domain PC: SMB response to 73 with status code 0 (OK)
>From non-domain PC: SMB command 75 (Tree connect to \\DomainPC\IPC$)
To non-domain PC: SMB response to 75 with status code C000035C
The whole of the above continues ad infinitum. Note that the user of the non-domain
PC is logged in with a username and password which is valid on the SAMBA domain. It
seems to me that the non-domain PC is trying to connect to the IPC$ share on the
domain PC. That machine is asking the PDC to authenticate the request, which it
does. However the connection to the share is then being rejected with a code of
C000035C. Instead of accepting this rejection, the non-domain PC is immediately
trying again.
Can anyone explain this please? If so, how can I stop it? The continuous requests
for authentication are driving the PDC and LDAP into the ground! Can anyone tell me
what status code C000035C means?
We really have to get this sorted out before our students start next week!!
Any help will be very much appreciated.
Phil.
