Version is 7.2.4

I don't think there are any firewalls between the filers and the AD, because this is a restricted datacenter anyway. But I will check that...

Hi all

This is a bit of a quick shot in the dark; but this does look like the filer is unable to make a connection to the DC in order to make an SMB RPC call or that an existing connection is proving unusable. Are there any firewalls or NAT devices between the filer and the DC(s) it is using? It might be worth seeing in their logs if they reset a connection, especially one that was idle for a while.

Another thing which would be of interest is what release of Ontap is running on the filer.

Just some quick thoughts.

cheers Kenneth Databasement bv

If its working for everyone else I'd be asking what's different about that user. do a cifs lookup <domain><Userid> to make sure the user account is resolvable from the filer get the user to try a different PC (to see if its a problem with the connection settings in the client registry) Check the user and computer account in AD for weirdness

one of our customers is geting this error constatly:

Tue Apr 15 14:20:19 GST [abcfas01: cifs.pipe.errorMsg:error]: CIFS: Error on named pipe with ADS10: Error connecting to server, open pipe failed Tue Apr 15 14:20:19 GST [abcfas01: smbrpc.pipeCreate.fail:error]: CIFSRPC: Attempt to create pipe LSA for LsarLookupNames failed with error 0xc000005e.

Any ideas?

Thanks in advance!
