-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi!
One of our users upgraded her Windows client from Windows XP 32 Bit to windows XP 64 bit and can not connect to any samba server in the network since, with one exception: there is one server, running samba-3.0.20b, which works. With other servers, running various samba versions up to samba-3.0.23c, the Windows client can not connect anymore (there are about 10 samba servers in the network) Windows just says "can not access" and "the request is not supported" (this is a rough translation, the original messages are in german) In the samba logfiles I see the following error (example logs from server "CDROMSRV" at aaa.bbb.ccc.27): [...] [2007/02/02 15:00:32, 3] smbd/sesssetup.c:reply_sesssetup_and_X_spnego(660) Doing spnego session setup [2007/02/02 15:00:32, 3] smbd/sesssetup.c:reply_sesssetup_and_X_spnego(691) NativeOS=[Windows XP 3790 Service Pack 1] NativeLanMan=[] PrimaryDomain=[Windows XP 5.2] [2007/02/02 15:00:32, 3] smbd/sesssetup.c:reply_spnego_negotiate(551) Got OID 1 3 6 1 4 1 311 2 2 10 [2007/02/02 15:00:32, 3] smbd/sesssetup.c:reply_spnego_negotiate(554) Got secblob of size 40 [2007/02/02 15:00:32, 3] libsmb/ntlmssp.c:debug_ntlmssp_flags(63) Got NTLMSSP neg_flags=0xe2088297 [2007/02/02 15:00:32, 3] lib/util_sock.c:open_socket_out(874) Connecting to aaa.bbb.ccc.1 at port 445 [2007/02/02 15:00:32, 3] auth/auth_server.c:server_cryptkey(75) connected to password server SRVL12 [2007/02/02 15:00:32, 3] auth/auth_server.c:server_cryptkey(100) got session [2007/02/02 15:00:32, 3] auth/auth_server.c:server_cryptkey(133) password server OK [2007/02/02 15:00:32, 3] auth/auth_server.c:auth_get_challenge_server(183) using password server validation [2007/02/02 15:00:32, 3] smbd/process.c:timeout_processing(1359) timeout_processing: End of file from client (client has disconnected).

Also all other (about 100) windows clients (running WinXP and Win2K, all 32 Bit) do not show any problems with any samba server. The one server which still works with the 64Bit WinXP works also as password server for the other samba servers (using "security=server" in a workgroup environment) This is at least suspect, because it seems to show a pattern: samba servers which are using the password server do not work with the new client, the samba server acting as password server does work. But I can not explain the difference and this setup works for all other clients since more than one year now without problems. The only change was the upgrade to 64 bit windows on this one client machine. Any ideas anyone? - - andreas - -- Andreas Haumer | mailto:[EMAIL PROTECTED] *x Software + Systeme | http://www.xss.co.at/ Karmarschgasse 51/2/20 | Tel: +43-1-6060114-0 A-1100 Vienna, Austria | Fax: +43-1-6060114-71 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFFyguSxJmyeGcXPhERAuHuAKC0+ldDyN9GnRIaEaaWmp3oTXe2sQCgpdHh Vumg9rdGPU8fY5kRfBQRyAA= =BMqz -----END PGP SIGNATURE----- -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/listinfo/samba
