Hi there,
first of all - I shudder reading "alfresco runs on a domain controller". I think its one of the first "best practices" mentioned by MS not to use a domain controller for other "big" stuff. If needs be, set up a secondary controller as Vm and run Alfresco Vm and Controller VM parallel on a host.

secondly - check out, if name resolution does still work during these times. Try hardcoding the server_a mapping in WINS and DNS files, provided by your DHCP server.

Thanks for the suggestion,

It is on a second domain controller , I have tried adding the hostname to DNS with still no joy.

Hi,

I'm sorry nobody could help you out, some questions are quickly answered here, others remain unanswered unfortunately
We are experiencing similar problems, sometimes Cifs works, sometimes it doesn't
I could find any solution yet and so I would appreciate any advice you want to share

Kind regards

Sorry, i havo no time to translate it, but this kind of configuration works with ubuntu 9.04

CIFS, es el protocolo SAMBA (SMB) para equipos Windows, en Alfresco se puede configurar para tener acceso todos los documentos existentes en los nodos y manejarlos como si se tratara de una carpeta local, permitiendo renombrar, cortar, pegar y todas las acciones propias del explorador de Windows pero con el repositorio de Alfresco, para poder configurarlo es necesario tener libres los puertos que utiliza samba por defecto, que son los siguientes:

-445
-137
-138
-139

*no debe estar corriendo el servicio de samba.

Para configurarlo en Alfresco se debe modificar el archivo
alfresco-globals.properties en la ruta:
{TOMCAT_HOME}/shared/classes/

Y agregar las siguientes lineas de configuración:

cifs.enabled=true
cifs.Server.Name=nombre_servidor
cifs.domain=nombre_dominio (opcional!)
cifs.hostanounce=true
cifs.broadcast=0.0.0.0 (direccion de la mascara de la red)
cifs.tcpipSMB.port=445
cifs.ipv6.enabled=false
cifs.netBIOSSMB.namePort=137
cifs.netBIOSSMB.datagramPort=138
cifs.netBIOSSMB.sessionPort=139

y no tener ninguna configuración personalizada de CIFS en el archivo:
tomcat/shared/classes/alfresco/extension/file-servers-custom.xml

*en caso de no ejecutar Alfresco con el usuario root, no se podrán utilizar estos puertos por necesitar privilegios, para esto, se pueden usar ip tables para usar los puertos 1445 1137 1138 y 1139, la configuración de ip tables es la siguiente.

iptables -t nat -A OUTPUT -d localhost -p $3 –dport $1 -j REDIRECT –to-ports $2
iptables -t nat -A PREROUTING -d $HOSTNAME -p $3 –dport $1 -j REDIRECT –to-ports $2
iptables -t nat -A OUTPUT -d $HOSTNAME -p $3 –dport $1 -j REDIRECT –to-ports $2

redirect 445 1445 tcp
redirect 139 1139 tcp
redirect 137 1137 udp
redirect 138 1138 udp

this is in Spanish

ok my problem was that as mentioned Alfresco was running very happy on a windows 2003 server, then along comes me and promote it to a domain controller well an ADC anyway. Now during the process of an AD promo it enables "file and print sharing" on the network cards. Now as mentioned I do not know anything about Alfresco and never want to know but this CIFS thing will not function very well with "file and print sharing" enabled. So I unchecked the option on both network cards and hey presto job done. It was lucky that the server we use for Alfresco does not need Windows "file and print sharing" if you only have one server then you are done for.

I do hope it helps somebody else, I am not sure how well documented this fix is, I spend 4 days trying to find a solution and couldn’t find it.

p.s. please let me know if it helps anybody

Hi bvadmin,

it did help!
although file and print sharing was turned off, during setup I followed these guidelines: http://wiki.alfresco.com/wiki/File_Server_Configuration#Vista_And_Windows_2008
and thus enabled NB-Datagram-In, NB-Name-In and NB-Session-In. After your tip I tried some different settings and now only NB-Session-In is enabled and everything worked like a charm! No more errors

Thank you very mutch for your help!

Kind regards,
Mieke

Great work, Mieke & bvadmin, did you think of updating the wiki about that ? That would be great.

Thank you very much bvadmin ,
for a long time this was a big issue for me.
Such a problem that was almost forcing me to drop alfresco, because my users were suffering this random loss of connectivity with the Alfresco CIFS share.
I've just disabled the file sharing service on the NIC. I'll post the definitive result but by now it's working perfectly.
You should update the wikipage.
thank you.
bye.
